Zoeller 53-0001 sump pump accessories Reviews & Ratings

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!

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.....

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.

This pump is mostly good. It pumps well, at the rated speed, and is quiet. My main complaint is that the float activation distance is almost 1" short of the specified distance. This is in water, and brand new. I think maybe the specification is based on the motion of the float in air, but in water it behaves a bit differently. The other thing I noticed was that water leaks out the gasket area and fairly high velocity, enough to erode or disturb the smaller rocks nearby. This is along about 1/4 of the perimeter, and I'm not referring to the purposely drilled hole. But I would buy it again, it is a good price.

I brought this pump because of the the 2 that I have in my basement drain tile sump are Zoeller. I have a 1/3 primary and 1/2 backup Zoeller sump pumps for my "TripleSafe Complete Sump Pump System". These pumps are not the cheapest but they are the best that I have experienced.

It's great.

It is working great so far. Only issue was that it must have been dropped during its shipment because the bar protecting the float was severely bent. Luckily I noticed it right away before I stuck it in the hole, and bent it back as best as I could with the bar off. It didn't seem to break the casing when dropped, but it could have.

Very happy with this product and Sump Pumps Direct.

Amazingly durable and low cost.

Well satisfied, my second pump, 1st lasted 13 years. I replaced the first because it was 13 years. Wanting to be safe.

Easy to install, super quiet and worth the small investment when it comes to piece of mind. My old unit was 16 years old and noisy, and you shipped my new pump in one day! The YouTube install video by a plumber for this model made the install very logical and quick. Everyone who is replacing theirs should buy this model for their residential application.

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.

They last 20+ Years.

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

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.

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

It works as I expected.

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.

Work horse. Fast shipping, Works Great.

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.

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.

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

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.

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.

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.

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

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!

Great product, exceptional value.

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

My first Zoeller M53 - 1/3 HP lasted 23 years. The pump is still functioning however, the switch finally malfunctioned and stayed in the on position. The pump is such a high quality and durable product I just purchased another one. I'm confident the new pump is of the same high quality. It is a very durable and reliable product. Guess what!! It is also nice and quiet.

P.S. I also ordered a new switch for the old pump and now I have a backup pump, which I'll probably never use. LOL

Easy installation. Definitely worth the purchase price. Great value!!

So far so good. I received it within 2 days replaced the same model that was 22 years old. If it lasts the same, we will be happy.

Have had other pumps bought at box stores that didnt last a year or 2. My last Zoeller lasted 12 years..

This sucker is well made, dependable and a terrific value. I've had other sump pumps, then I've had the Zoeller M53. This is the one we count on, so we can sleep at night...no worries.

I have two pumps in the basement. 1-Rigid, 1 Zoeller. I have replaced the Rigid pump once under warranty in the first three years, then again at about the 6th year. My other pump finally quit (Installed in 2004) when I pulled it out I noticed it was a Zoeller- about 13.5 years with out a single problem! I'm definitely buying Zoeller from now on.

Installed and tested...So far so good...Waiting for spring rains.

I had one of these installed in my basement 9 years ago. I finally got restful sleep on rainy nights after that. Finally had to get a new one, and got the same model. Works great and built to last. Highly recommend this pump for anyone needing one.

30 inches of rain in the past 5 weeks in N. Calif. and still raining - Saved us several times this winter.

Very well made and the name brand has a reputation that speaks volumes.

Super.

Super quality sales staff. I have set the pump up as a back up..So it has not been used except by a 10 minute test. The staff was awesome shipping fast related info awesome.

My first Zoeller pump lasted about 12 years. It was working perfect (even though it looked like a pile of rust) but the switch was sticky so I replaced it with a Wayne and kept it as a backup. The Wayne lasted about 8 years and froze up. I pulled out my pile of rust Zoeller and it worked perfect for me until I got my new Zoeller installed. I'm still keeping the old "pile of rust" Zoeller as my backup. I use it in a sump to drain my flooded back yard in heavy rains. I'm not knocking any other brands, but I don't think you can beat a Zoeller for dependability and durability.

We have three sumps each with a 1/3 HP Zoeller M53. After 7 years, the switches on two of them began sticking. I replaced the pumps and check valves (I was highly advised to do so). Being exact replacements, the change overs each took 20 minutes. I received great advice from Bob at Sump Pumps Direct.

Only had it for a month, working great.

Very happy with this. It is a very quiet machine and easy to install.

I have always had good luck with Zoeller pumps.

I was a little hesitant to order online, I am one who likes to touch what I purchase. All the feedback was positive, so I gave it a shot. It arrived quickly and in good shape. I was worried that being so heavy it would tear through the box, it didn't. Well packaged. I also purchased the check valve. My current pump did not have a check valve and I'm glad I installed one this time. Extremely quiet, the first heavy rain my wife called me at work and said it wasn't working. I asked her if there was water around the lid, she said no and I said it is working, just quite. I confirmed when I arrived home that is did a great job removing the water and that it was very quiet during operation.

Great price. My system wanted $300.00 for the pump plus service call. Saved me a bunch. Thanks.

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.

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 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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Much higher quality and better priced than what the big box stores have on their shelves. Compact and easy to install. Follow the instructions.

Pump lasts years even in commercial use. Bought and used over 20 of these over the last 5 years.

I've had the pump and basin installed for about two weeks and so far I am very pleased. Have not had a really hard rain, but when tested, it really pumped out the water with about a 9 foot lift. Thought the basin and top were a little expensive, but they are of good quality and should last forever. So, maybe I should consider them an investment!!

The Zoeller M53D is a great sump pump. I replaced my 6-year old M53D before it had a chance to fail. My choice, since I know it probably would have lasted many more years. However, the shipping packaging is inadequate for the wieght of the pump. Single layer cardboard box had some holes worn in it when it arrived. No damage and I blame Zoeller not SPD for this, but SPD should consider an overpack.

AS advertised this pump works great. I'm very satisfied not only withe the pump but the support I received from the company. Great product. I also bought the basin and check valve.

I use Zoeller pumps for all of my sump pump needs. They work very well. Have yet to have one falter.

This was a replacement for the Zoeller M53 pump. Great pump, and your service was as advertised. You definitely will be used again.
