Zoeller 53-0001 sump pump accessories Reviews & Ratings

As soon as I opened the box, the quality improvement over my old pump was obvious. Then, once I installed the Zoeller and observed its operation, was even more pleased.

Bought as a spare left on a shelf in basement for when needed got it out last week and the pump does not shut off.

This beast works fast! I may have gone overkill because despite the fact I get a lot of water in my crawl space in a heavy rain, this pump doesn’t stay on long, it pumps the water out very quickly!!

Does the work I needed to do. Have had similar pumps in the past.

I looked for a pump at a lot of stores but all made in China. Not for me.

We are new home owners and 6 months in our sump pump failed. Horrible inspector missed a lot of stuff he should have at least told us it was old. I had a plumber out and quoted me $1200 to put in sump and back up sump. He wanted over double for the sump alone.

It took my boyfriend about 20 minutes to switch out the old one and the Zoeller works great. I did do research into good quality brands and watched some YouTube videos of real plumbers recommending this brand. We are going to add a battery in the near future. We don’t loose power much here but just in case. Very happy so far.

Customer service was wonderful. I forgot to add on a check valve, they ordered it right away and waived the shipping. Both arrived very fast! 5 stars for Sump Pumps Direct. Thank You!!!

After 14 years of continuous service, I had to replace a Zoeller M53 because the float switch mechanism had failed. It might have been repaired, but after 14 years of 24/7 use, I figured it was time for a replacement. After checking around, I got another M53. It was too affordable to take a chance on a different pump that might not be as reliable. Super easy to install, too. It's heavy, but in my application it is permanently in place. If I had to move it around a lot, I would probably want something lighter. But, I'll trade off weight for another 14 years.

The only sump pump to buy its made out of cast iron and its proudly made in the USA.

The pump is the most popular pump. But the switch started sleeping after 56 year service from my experience of two such pumps at two houses. I hope Zoeller has improved quality of the switch. This time, I bought a new pump with a switch kit. I will replace the switch of the sleeping pump as a spare.

Much quieter than my previous pump. Runs more often because of the short throw of the float switch.

Easy installation, smooth reliable operation so far. Concerned about switch problem mentioned on other
reviews, ordered extra switch just in case.

My pump is an exact duplicate of the pump the builder installed. I purchased this pump as a backup pump and haven’t needed to use it. Current pump works perfect.

They last 20+ Years.

I worked wholesale in plumbing/electrical for 23 years. I knew when buying this pump it is the best available to do my job. Glad to have the advantage of knowing products when I need them.

My old one was still running after 7 years. Put a new one in and now the old is the back up. New one is even quieter than the old one. Excellent performance and reliability.

Got my new pump and it seemed to work well for about two months. Out of nowhere, it stopped working and my basement flooded. It did start back up after wiggling it. But no idea why or how it just stopped. Very frustrated this would happen out of nowhere with a brand new pump. Basement floor flooded.....

It works as I expected.

I have two of the Zoeller M53 sump pumps in my basement and during the Spring/Summer months, they can run a lot! I need good quality pumps here, and the Zoeller M53 hasn't let me down yet!

Our Zoeller Cast Iron Submersible Sump Pump lasted years with daily use. I recommend this pump because of its durability and reliability. It has handled all of our sump needs.

This replaces another M53 pump that ran faithfully every spring for the last 26 years. Its switch finally gave out even though the pump was still working. I hope this one lasts at least half as long. They need to package these more carefully for shipment though. The box it comes in does not protect it from scuffing to the powder coat.

I have to say this sump pump takes a beating whenever we have a winter thaw and in the spring. This sump pump cycles every 15 seconds during the that time. No sump pump that I've owned has been able to compare with this M-53. I did change out the switch this year after owning it for 5 years...no biggie there. All the other ones (Wayne) and ( pentair) burned out after 2 years. Zoeller m-53 rocks!

I bought and installed this pump in a sump pit to keep my garage from flooding in the heavy Florida summer thunder storms. I installed the Zoeller check valve as well and followed the directions carefully. However, it is just not moving water according to the specs. The discharge pipe heads 90 degrees just above the check valve and runs 30 feet on basically level ground.

Its raining heavy now and the sump pit is completely submerged in water and there is a tiny flow coming out the discharge end of the system. This thing should be pumping out at least 20 gal/min according to the specs but it is doing about 1 gallon every 3 minutes . . . less flow than my sink faucet! I was careful to clean the pit of debris and there is a grate to catch anything big so I dont know what the problem is, but I'm very disappointed.

Two days delivery as promised. It is the same model that came with house and was easy to replace and install. Cut PVC, reconnect PVC coupling in 30 mins. Its been a month now since I replaced it and it is good now. Will update later date.

Worked fine so far. Too early to comment on reliability / durability.

It was very easy to replace what the waterproofing company installed many years ago. I figured if they use it it must be a reputable product. Saved on a service call and an escalated value over retail. No brainer

Unit has only been installed for a few weeks. Hopeful it will perform well and for a long period but too early to tell.

While the unit seem rugged, it was not packed well - zero packing. A big hole in the side of the carton where the unit obviously pushed/crushed its way out.

Seems well constructed and Zoeller generally has a good rep,

The instructions were very minimal and not suitable for a DYI person like myself. They may be good for an experienced installer (who probably does not need them) but for an non-pro they should be enlarged - the cost would be so little to double the size.

Unit operates the same as the very old pump it replaced, so I scored it at 3 since is was as good but not better than the old one.

We have a high water table and actually have 2 of these in the basement. I just bought 2 new ones as 1 of them quit working. This is the pump I always buy. No problems. They eventually wear out like anything mechanical and when they do I just order another Zoeller. I ordered them online and they arrived the next day!

I installed two new pumps with check valve and pump bases. Great package, easy assembly.

I like the fact that Zoeller fully tests the product before its shipped. I replaced an existing Zoeller M53 that was still working but about 10 yrs old. The only thing I don't like is the float is not adjustable. I would prefer being able to pump more water on each cycle to prevent short cycling where the pump is running every few minutes as it was during our recent heavy snowmelt and rain. In retrospect I probably should have gotten a non-automatic pump with a adjustable float.

Great product, exceptional value.

Great pump easy to install.

Zoeller makes some of the best pumps in the market!!! Only sump and grinder pumps I use!!! Hands down that work and work flawlessly!!

Love this little pump. The best part is you plug it in and leave it when you know the rain is coming

Easy to use and install, works great.

I can't believe people still buy these. This technology is terribly old, the pump draws so much power, yet moves such a sad amount of water - 2000 GPH at a 9AMP Draw (25 starting amps). Good luck trying to use a backup generator if your power is out for a long time, you'll need a 3000 Watt generator just for the pump. The float gets stuck and won't turn on, or the switch fails over time, the thing runs indefinitely. I had this pump in my basement and along came a bad storm, good thing I had a backup pump, there would have been a flood.

Fast shipping, got it installed just in the nick of time. 5.70 inches of rain over 2 days and it handled just fine.

Actually I bought this to replace a M53, but I spent 3 hrs cleaning the crud off of the old one which was up to 1/4" thick in some spots and was impeding the float switch from working. After seeing it looked like new and now worked again I lowered it back into the hole and hooked it back up. Hope it works for another 6 years, if not I got a brand new backup on the shelf. Actually up here in NY, Liberty pumps are the big seller as they are a local company but from what I see of the Zoeller the construction is far superior and I'm 76 yrs old and I've changed a lot of sump pumps??

Tough and very reliable.

Quiet and works like a charm.

I just installed The pump last week just in time for our 5 ft. Snow fall melt on Lake Erie and it is working great. One thing I like, the pump is very quiet, almost hear nothing standing by it in the basement. Seems to be very well constructed, I kind of checked it over. Hopefully it lasts a long time.

I bought this sump pump before my old one stopped working. It had a been a number of years since I purchased my last pump and I wanted some peace of mind. We have had a number of storms where this pump has been in constant use and it has worked as planned. It is a good quality pump.

Very pleased with product and even more pleased with Zoeller's responsiveness and commitment to servicing customer's needs.

Purchased this pump from a local supplier. 1st float switch failed after two years, returned to the dealer, they said they stopped carrying the pump due to the float switch issue. They did have a replacement switch. 2nd switch failed in less than two years. I purchased a replacement from sumppumpsdirect.com.

Easy to set up. Works every time. Don't have to worry when the rain comes. Just gives me a piece of mine when I am gone from the house. Its heavy but it's make so it will last a long time.

I replaced a 20 year old M53 with the same unit. The switch finally gave out after 20 years of being run on average of once a day. Not bad!

Great sump pump!!

It is a solid product. No problem so far after using it for two months. Hope it will last for years.

Excellent pump. It is hard to find a good quality product now days. This is it. I install it about 45 days ago. Works well, can't hardly hear it run. Nice and quiet. Wish I would have bought it 20 years ago.

I have two sump pump pits in my house. I replaced a 16 year old Zoeller with the M53 and this year the other 19 year old Zoeller went out. You can't go wrong with a Zoeller. I suspect in both cases it was the switch that went out and not the pump itself. I like to have a spare on hand just in case and may buy a switch repair kit, test it, and throw it on a shelf for a rainy day. Excellent pump and the M53 will work in most applications. Very heavy duty and the poly resin base does not hinder its durability in my application. Buy with confidence.

Fast delivery, easy install. Works fine. Only gripe, the power cords were shorter than the pumps I replaced, a few more inches on these would have made instal a breeze as the take out pumps had dedicated power outlets. Like the handle on the top.

This M53 replaced my old M53 that lasted 10+ years.

I have installed dozens of these in customers houses over the years. Most of them are still working today. Some have needed replacement but only due to corrosive water entering the sump.

On second Zoeller sump pump and had trouble with both. First stopped working and flooded basement and now have another one that float switch keeps sticking and pump wont shut off.

Did a lot of research and we chose your product works great in crawl space.

Will always buy Zoeller.

Excellent. Strong, efficient and easy to install.

This product was exactly what I was looking for and works perfectly!

It works!

Pump is very reliable and low maintenance.

Easy to install and worked great.

Love this pump. Wouldn't buy any other brand, A true work horse.

My house was built in 2001, with a Zoeller model 53 installed. I have had no problems with this pump since then. I had heard somewhere that it was a good idea to replace sump pumps every 10 years, so I pulled of the sump cover and stuck my head in with a trouble light. I noticed that the switch housing looked pretty rusty. I decided to go ahead and replace the pump before I had a problem. I knew that Zoeller pumps were made in Louisville and I decided to stick with them. I initially planned to buy this pump from one of the big box home improvement retailers. When I learned that both now only carried imports in their stores, I went to the internet and found this on-line seller. Yeah!

I did some research, and after looking on most reviews for brands I decided to give Zoeller a shot. Could not be happier with the performance of this american beauty. It's quiet, powerful, and well built. Also, because I saved about $5k doing it myself.
Buy american amigos!

I bought this model 2 years ago. It was recommended and installed by a plumber. It died. It can not be repaired. The plumber said that Zoeller will only give a one year warranty. Since the installation, I have become a widow. I do not have extra money to be having a sump pump installed every 2 years. This is not a good product and it stinks that Zoeller will not pay for a brand new one. A product should last more than 2 years.

The pump impeller housing, half of which is made of plastic, leaked on first use. I removed pump and tightened screws, but it still leaked. I contacted Zoeller and was told by the tech. support guy, after consulting his supervisor, that it "shouldn't be a problem." I thought my pump was for the purpose of removing water, not spraying it back into the sump basin.

We have 4 sump pumps in our basement and have been using these. They do a good job when they are working but always die after 2 years give or take. They should last longer for the money. I would gladly pay more for a pump that lasts longer

We've lived for years with a cheap sump pump. Very unreliable, and noisy. When it stopped working consistently, we purchased the Zoeller M-53. Though more expensive than what we had before, it's much more what a REAL sump pump should be - heavy, substantial, and quiet.

I am very happy with my M53 pump. I bought it because the float valve was getting a little balky on my old M53 after 17 years. Thought I would give my old pump a proper retirement and get a new one. SPD was great on the phone and my new pump was delivered within 24 hours (no express stuff. just regular shipping). The how to install it video on the SPD site was great and I installed it myself with no problems.

Thanks SPD

Used cheap Flotec stand up sump pump for 20 years previously. Noisy and needing float ball adjustments constantly, but reliable. Replaced with Zoeller's 53 model, with plumber's recommendation. Very quite and reliable but definitely not durable. I just put in my 3rd one in 10 tears, float switch apparently a week spot. I will revisit this review after seeing how long #3 lasts.

Had to throw away the M53 today. Probably would have lasted longer than the 7-8 years of very little usage. But, three times I found the float stuck in the "on" position. Once was due to ice in the exit pipe outdoors. But the water in the hole was already very warm, meaning that the pump had been running for possibly days without stopping. Still worked, though. Next, I had a new water heater installed, and the installer elected (on his own) to drain the old tank into my sump hole. So, the next time I had a lot of rain, the sump hole filled, and the pump was "on". I reached down into the hole, swished the water around, and also disassembled some of the piping. I found "rocks" of old-water-heater deposits/sediment had clogged the pump. Freed it up, and it worked. The third time float got stuck in "on" position, it was stuck for no obvious extraneous reason. Just old and lacking smooth functioning. Still worked. Then, last week, it failed altogether. Not a bad pump. Pretty average, I would say. But if it had not been for the ice blockage and the water heater "rocks", I think it would still be functional. Beware. Am now seeking a pump with DC backup and an alarm to tell me if a failure is occuring. Could save me a flood and save my next pump from over-running. My basis of comparison is the pump in my house as a kid. Pump was still working when house was sold after 15-years of usage. Pump ran probably about 50 to 100 cycles per year. Exit pipe was below ground, so ice was less likely.

I already have two Zoeller pumps in two different sumps in my basement and I'm very happy with them. They are going on 4 years old and I bought a 3rd one for backup just in case.

Glad I found PED/SPD!
In the past, I could find the Zoeller M53 pump at some hardware store, but lately, it's been harder to find.

I have consistently been using Zoeller M53 pumps since our house was built 35 years ago. They provide dependable service for many many years.

This new sump pump is my backup. I always keep a replacement pump (plus the PVC pipe, fittings, and glue) on the shelf for that day, years from now, when my current pump starts to misbehave.

Product came quickly, good support from the website, exactly as advertised. The ups delivery guy and I both took pictures before I opened the box, expecting damage.

One leg of the pump was bent a bit, but everything worked. Why this company is unclear on the concept of putting some packing material inside after shipping pumps around for years is a mystery to me.

I will buy from them again, but I will talk to someone at the company to ensure they pack things correctly.

Had to return pump due to damage. Shipping container was a very flimsy cardboard box and arrived with six puncture holes in it. Powder coating was knocked off at ten places down to the bare metal. Can't believe anyone would ship a 22 pound cast iron pump in such an inadequate container.

My sump pump was 17 years old, still working but I installed the M53 Zoeller. Very happy with it so far, it worked fine with the 8 inches of rain in two days last month. Happy to buy things still "Made in the USA. I have purchased a second M53 for the second sump.

I believe the Zoeller pumps are very well made. I have a situation where the pump turns off and on very frequently. The pump switch has failed on two different occasions. It locks in the on position so the pump does not shut off. The second time, the pump was still under warranty, Zoeller replaced the pump, no questions asked. I'm concerned that this has happened twice, but I think the frequency the pump goes on and off has a lot to do with the failure over time. I would still buy another Zoeller pump.

Fast efficient shipping and tech help. Zoeller pumps are the best. Last long and very reliable.

Must use because of shallow pit.

So far, so good. Very quiet as well.

This is the first time I have used your pump....so far its good. During my worst rain storms since installing (Aug 2015), the pump had to start every 10-15 seconds after shutting off, so it gets heavily exercised. My experience with other previous pumps is that the switch has been its weakest link. So I think it would be great if you could design an "on/off" counter to register how many times it starts. If you have any statistics on the "expected lifetime" of your switch, then that could give me some idea when to replace the switch before it fails.....preventative maintenance.

I worked for a coal mine for 25 years and in all of our sumps we used Zoeller Sump Pumps in our conveyor pits. They gave us minimal problems for the 25 years. So when I needed a sump pump for my house, I wouldn't trust any other pump than Zoeller.

I own 4 Zoeller sump pumps: 2 in my basement, one for my pool, and one for my son to pump water out of his duck blind. Won't use anything but Zoeller.

Have not used it yet. Only tested it. Seems to be a very good pump. Only heard good things from local and others from this pump, only thing I don't understand is box says put vent hole in pipe but the pump already has one. AND plumbers say of pump has one then don't need one on pipe. Then others say yes do. So little confusing. But I believe this pump will be very good.

This pump is working great. It replaced a less than 2 year old plastic pump that was clogged up with sediment. We have had ridiculous amounts of rain since putting the pump in and it has not had any problems.

This was a perfect replacement for previous Zoeller M53. Did not have to alter anything. Hope to get another 5 years out of this one.

Put in another top brand and it lasted a couple of months. It was apparent from the start that the Zoeller was of much better quality. Works great so far. Time will tell.

Our Zoeller pump is just now having switch issues after 15 years of hard sump work. We are replacing the switch for $30 and will keep on trucking. This is definitely the best pump around, in my opinion.

Installed myself in under 2 hours... Buy a check valve too. It's been operating for 1 month. Drains the sump well very fast. Construction feels very high quality.

Pump came very quickly. Excellent quality with long durability. Excellent value for the money. Would buy again in a heartbeat.

I replaced my previous sump pump of 11 years. It had worked well, and I wanted to make sure I replaced it with a pump that would be as reliable and long-lasting.

I read the write-up on the Zoeller M53, saw that it appeared to be a very good product, and was happy with the price.

It arrived within three days, and immediately on opening the box I was impressed with how sturdy and well made the pump appeared to be.

After installing the pump the first thing I noticed was how quiet it was when running. I work out of my basement, about 15 feet away from where the pump is, and I can barely hear it.

It has been less than a month since I installed the pump, but we have had several rain storms since then and the pump has been working well. I am very pleased with the purchase.

Great speedy Service. Many Thanks.

I bought the M53 as part of the Zoeller ProPak system with battery backup. Had it professionally installed in October 2012 and it worked great through hurricane Sandy. It rained today and about 4-5 inches of water went into the basement sump but not enough to active the pump. I decided to test the pump, activated the motor via the float switch and it wouldn't pump out the water. The motor just continued to run. You got to be kidding me! I used my shop vac to suck all the water out and checked for obstructions but found none. Hopefully the guy that installed in (if he ever returns my phone calls) can get a replacement unit. However, how can I have any faith in this pump now? My previous 1/2 HP pump was going on 10 years of faithful service but I wanted a pump with emergency backup.

It is a very rugged high performing pump. I do have one problem. My sump almost always has water. It is the water table. My house is right off of the beach and across from a salt water inlet. High tides push the water table up. When I installed the pump at high tide the pump cycled on and off every 10 minutes. Is there a method to adjust the float? or change the cycle point? or do I need a different model with a higher range of motion?? Love the heaviness and performance but had to put the old pump with the float on a tether back in.

This pump compares to a current Zoeller I am using and is very many years old. This pump was unused for at least the last 3 years and during an emergency I took it out and it has endured throughout much rigorous use and is still working well. I recently installed the new Zoeller pump so it is still to soon to evaluate its performance and longevity but during preliminary testing it seemed to work very well.

I am a Building Contractor of 50 years and have enormous expertise with sump pumps, I have seen new pumps fail within months and other pumps last more than 10 years without failure. Zoeller is a fine quality pump and I expect it to work very well for a long time to come.

I am a little old lady. My recently installed sump pump failed after only two years! It was installed by my contractor.
I called my son who repairs and installs elevator to ask for assistance to see why my pump was not working.

He said the pump"s base was broken and probably had been since installation as it was a made in China pump with a plastic base.
He asked me to research a new one and gave me specifications. It must be cast iron,it must be made in the USA etc.

I found the Zoeller on your website, it had all the requirements my son asked for. I ordered it, it came within two days and my son installed it immediately.

He loved the quality of the pump and talked about it
for awhile. He was delighted with the weight (heavy)
and quality of the pump. I could only get this happy over a piece of chocolate!!

I was so impressed with finding an American made piece of equipment that my son was so impressed with that I was prompted to write and thank your company.

Thank you for carrying a quality product and making it so easy to order.

Thank you all and a Happy New Year.

He asked me to research a new one and gave me specifications. It must be cast iron,it must be made in the USA etc.

Zoeller is the only pump I'll use. Long lasting, solidly built. The shortest service life I ever got on an M53 was 6 1/2 years, and that was being used as an effluent ejection pump in the septic. (The impeller shaft bearing failed). The one that is in the laundry crock has been in service since 1992 and still going strong. Great products at a fair price.

So I bought this after extensive research as a replacement for my 1/3 Hp Rigid Stainless steel unit.

Worked great but the float setup in my small sump causes it to cycle rather rapidly - it ejects the water so quickly it shuts off after about 15 seconds. The problem comes when my sump is re-filling quickly. The pump will cycle on and off every few minutes. Contacts burnt and stuck on after a year of use,- SumpPumpsDirect covered it under the warranty.

I purchased this pump to replace one that was in a sink pump that was used for 8 years. It was the exact replacement pump and it worked perfectly. I ordered it on a Sunday night and it was delivered on Wednesday via Fed and I installed it on Thursday. I could not ask for better service.

After deciding to put a bathroom in the basement of a house we recently bought, I found out there were no drains! So the contractor decided to go with a sump for the shower & vanity, and the washing machine could be tied in with it. It previously drained through a pipe in the floor.

The first pump was a cheap thing from a big box store that didn't make it a year, so I decided to look online for a quality pump to replace it, and hopefully I have. Construction and other features of it are good, and its made in the U.S.!

Just what I was looking for. Good design and heavy duty. Less than I expected to pay. Arrived in good shape in a timely manor. It has been installed for a while now and has been working well. I'll be saving this site in my favorites.

May basement had a sump pump that died causing 12k in damage. I went on this website and the quality, price no tax and free shipping second to none. I was impressed of the quality of the pump, easy to install as well. Actually thinking of getting a second one as a back up. Hope it last.

I bought two of these pumps to replace the 1/3 hp Bubba pumps that failed in less than two years and flooded my basement. The Zoeller pumps are high quality and are much quieter that the pumps they replaced. My plumber said this is the only brand they use and have never had to replace one for warranty issues. The Zoeller check valves are also high quality. I have no regrets and plan to buy these pumps again in the future.
