Q: I installed the Zoeller M53 with the recommended 1 1/2" Zoeller check valve. I mounted the check valve about 5' above the base of the pump, about 2 1/2' above the check valve the pipe makes a 90 degree turn. All is operating well - Leading up to a question, I think I am getting some water hammer. The pump starts smooth but when it switches off it rattles the pipes. Any suggestions? I installed according to directions. by Steve from North Carolina on May 14, 2012
A: You might try to brace and/or pad any area of the discharge pipe that may be coming in direct contact with any walls, ceilings or joists to try to reduce the vibration that is being caused by the sudden reversal of the water flow once that pump switches off and that check valve slams shut. Sometimes you will need to install a check valve with a spring-loaded rubber flapper like the PeakFlow model PFQCCV15 Clear Quiet Check Valve 1-1/2" or the Basement Watchdog Klunkless Check Valve. These check valves should help reduce the "thumping" sound if they don't eliminate it all together. by Jim, Product Expert
Q: live 1 bloock from river i get water from that and ground water. i have 1 zollerm53 if it stops iam done. i want 2sump pumps 1 higher tha other. for safty by Bill from New Jersey on April 28, 2012
A: You are describing a fairly common application. A lot of homeowners will install 2 sump pumps in their sump basin for this type of situation. The main pump will be set to activate at about 12 inches of water and the secondary pump will be set to activate at about 14-16 inches of water in the event the main pump cannot handle the amount of water coming in. Please note however, that you will also need protection in the event of a power outage. In that case, your best defense is a higher output BATTERY BACKUP SYSTEM or a small STANDBY GENERATOR. by Jim, Product Expert
Q: I have a Zoeller M53 in a basement sump 24 in. deep. the pump rests on the bottom and the float activates Approx. every hour for maybe 5 seconds max. Can i raise the pump in the sump 6 inches or so and therefore pump more water per cycle. Thereby cycling only maybe only every two hours. If I raise it 6 in. the water table would still be approx. 8 in. below underside of concrete floor when the float activates. This pump is approx 7 years old, seems to work fine , do I need to consider replacing and with what. Located in NW Ohio and water table is fairly high. by David O from Ohio on January 23, 2012
A: The switch on the Zoeller M53 has about a 4 1/4" differential so by raising your pump in your basin, you will effect the level at which the pump will activate, however you will NOT effect how much water is pumped out. Your only option would be to either replace the pump with a different type of switch, possibly a tether or electronic switch or by rigging the switch on your M53 to stay on and then add another "piggyback" style switch. The Pro Series model USC3, the Superior model 92005 or the StromPro model ING-2-10-1B switches would all give you the capability of adjusting the actual runtime of your pump. by Jim, Product Expert
Q: I am torn between which Zoeller pump would be best for my application. My basement is 104' and currently takes in approximately 3" of water when there is a hard rain. The water is only on one side of the basement and never comes up on the other. Would you recommend a 1/3 hp or 1/2? by Joe from New Jersey on January 15, 2012
A: Without knowing more specifics like the water table, area of the country you live in, actual square footage of your basement, etc., it really is difficult to answer. I can tell you that most average sized homes in an average water table area can usually get away with a 1/3HP or 1/2HP pump. Beware of over-sizing the pump as it could cause the pump to cycle too frequently thereby reducing the life of the pump. You don't want to just install a 3/4HP or 1HP pump just for the sake of it. by Jim, Product Expert
Q: Is the Zoeller m53 availiable with a longer cord? by Chris Allphin from California on January 09, 2012
A: Unfortunately not however, the N53 non-automatic model does come with a 15 foot power cord. You would just need to purchase the float switch of your choice separately. by Jim, Product Expert
Q: can i buy a new switch for m53 by Anonymous on November 14, 2011
A: Yes, you can, but you need to purchase it direct from Zoeller. You can reach them at (800) 928-7867. by Jim, Product Expert
Q: I purchased a super-sump 1/3 hp Zoellar cast iron pump last July. I would like to buy a generator to run that sump pump plus my icebox which takes 6.5 amps/115 volts. What size generator would I need to run both of these during a storm? Thank you. by Kathy Morocco from Virginia on July 31, 2011
A: The starting amps for the M53 are 25.9. You would really need to know the starting amp rating for your ice box to get an accurate number to size your generator. The 6.5 amps you mention are the running amps. The compressors on the icebox always require more amperage or power to start because of the extra torque needed. Once you can obtain that number, multiply it by the voltage (120), add 3108 (the starting watts for the M53 pump) and add 20% to the total. That would tell you exactly what size generator you would need to run both appliances at the same time. Amps times volts give you watts. I can ASSUME that the icebox would be in the neighborhood of 32 amps. At that rate, together with the sump pump running at the same time, I would estimate that you would need between a 6000 and 7000 watt rated generator. If you can get away with switching between the two appliances, you could go with a 4000-5000 watt rated generator. by Jim, Product Expert
Q: wanting to buy a battery backup system for the M 53 . Should I buy the 507 or 510? by Bill Knight from Illinois on April 30, 2011
A: That answer would be based on how much water you feel you would need to pump during a power outage. The 507 will pump 900 GPH at 10 feet and the 510 will pump 1320 GPH at 10 feet. We do carry other brands that will also be compatible with your pump and are capable of pumping more if you feel you need it. by Jim, Product Expert
Q: Hi there, I'm planning on using this pump and a Jackel sump basin ( or something like that) to move water from a "lake" in my diveway, about 50' horizontally to a flower bed. How far will this pump move the water? No head, actually probably a foot or two lower. I'll be using 1.25" PVC terminating in some sort of perforated drain pipe... HELP!! by Jeff Bell from North Carolina on February 11, 2011
A: A better selection might be one of THESE as it would be better suited to the application. You might also check out this TRANSFER PUMP if you prefer an electric alternative. by Jim, Product Expert
Q: Can you raise the vertical float switch to accommodate a higher water level in the sump pump pit on this Zoeller submersible sump pump, if so, how? by Daniel from Illinois on February 07, 2011
A: These Zoeller submersible sump pumps have a factory set pumping range and are unable to be adjusted to accommodate a higher water level. by Jim, Product Expert
Q: My pump keeps running, is it the switch or the pump? by Dennis Lainson from Iowa on February 05, 2011
A: In most cases, if your pump keeps running, it is most likely a switch problem. by Jim, Product Expert
Q: I have a Zoeller submersible sump pump don't no the model but it has a 9 foot cord, is it a m53? I found it running with no water in the pit,unplugged it and moved the float up and down a few times and plugged it back in, and it is working okay now. The pump is about 6 years old, should i replace it or is there something else i can do. Sort of worried it might fail and flood the basement. by Gary Smith from Ohio on January 23, 2011
A: The M53 is the most popular 1/3 HP Zoeller pump, so it would probably be safe to say that's the model.
Normally a pump should last 7-10 year, but to be on the safe side, it's usually best to replace a pump after it reaches the 5-7 year mark. by Jim, Product Expert
Q: the pump is not turning off. Is the switch stuck? Can it be replaced? I gave it a good rap, but to no avail. The zoeller M53 unit is approximately 3 years old. by Bill Howard from Georgia on January 15, 2011
A: Hello Bill, It's possible there is some debris in the switch mechanism that may be causing the switch to fail. You might want to give Zoeller Tech Support a call at (800) 928-7867. Those pumps do carry a 1 year warranty. by Jim, Product Expert
Q: Would this pump be suitable for a 12' x 12' basement? by Cody Dix from Ohio on January 10, 2011
A: The interior dimensions of a basement aren't a major factor in sizing a sump pump correctly.
Monitoring your current pump during normal operation and during a storm can give you a better idea of what size pump you would need. by Jim, Product Expert
Q: What is a Vertical Float Switch? by Jon from Illinois on December 29, 2010
A: A vertical float switch is a ball that floats above the water. As the water level rises so does the float which, at some point, it will trigger the switch to turn the pump on. This float has limited movement up and down and side to side, giving it less freedom of movement and less of a chance to get stuck as a tethered float would. by Jim, Product Expert
Tired of having to run to the Orange Giant to replace the store brand sump pump you purchased? If so, you need to read on.
The M53 is well known among plumbers as the sump pump of choice for the average homeowner. Zoeller is known for their quality and dependability and this pump is a big reason for that reputation.
With a Cast Iron Switch Case, Motor & Pump Housing the pump is built to last and can pump out 2680GPH at 5 Feet. The unit has a clog free design that can pass 1/2" diameter solids.
The M53 comes with a one year warranty and a great reputation that will put your mind at ease and makes our "Better" recommendation.

Water Alarm Worth Every Penny
I had some water issues and resolved them all with rain gutter cleaning, grading and sump pump replacement. As a precaution I purchased three competitor water alarms from another website. They worked but were almost inaudible unless in the same room. I tried the Basement Watchdog and was extremely impressed! Very loud, almost as loud as a smoke detector. I have several of these around the home and have purchased several for friends. Highly, highly recommended and no I don't have stock in this company!
My primary sump pump is the Zoeller 53. I've had it two years, no problems, it's built like a tank, quiet and powerful. Highly recommended. One tip I'll share. When I bought the Zoeller at the plumbing supply house I asked about replacing the check valve. The salesman/technician asked if I was having any issues with the current one and I said no, he said why replace it. Got home and commenced installation of my new Zoeller 53 and the check valve split from rot. Had to run out and get a new one. I recommend replace your valve when you replace your pump, cheap insurance and gives peace of mind.
My next objective is a backup.

Back Yard Pump
My pump has only seen 1 storm of duty but performed well. I need it to be able to eat up some oak eaves that get into the sump.
It did this very well. The case is heavy cast iron and seems very well made. The float switch is what got me to consider this unit. It seems like it should give me several years of service.

Nothing Like It
My original Zoeller pump ran for 14 years with out any problems, until the switch fried up. So for 14 years of great performance I figured I wouldn't push it and just replace the switch. Ordered the new one and it was here in know time and installed in 10 minutes and I pray I don't have to worry about it for another 14 years. Great item and you can count on it.

Good Product But Service Was Even Better!
Ordered a new zoeller m53 sump pump and basement watchdog klunkless check valve. First valve had crack in housing which I didn't notice until after installation. So I emailed service and they sent me a new one free of charge which I received the next day, and didn't even have to return ship the bad one. That is what I call customer service!!!
Will order another one from sump pumps direct , when my secondary pump dies. But this valve is awesome, it makes absolutely no noise when pump shuts down, not like the old type that sounded like an intruder busting down my front door every few minutes! Pump Is quiet and powerful, look forward to many years of service!

Surpassed All Expectations
My basement has two sumps...one for groundwater and one for greywater from the utility sink/floor drain. Well, the latter hasn't had a working float in months, and so between wash loads I had to manually plug/unplug the pump to drain the sump pit. Well, I think after a while of having too much standing water in there, it caused a smell, and my wife had enough. I browsed around online, found your website, and then noticed that you're local! I drove down to the showroom after work, told your guy what I wanted, and within a few minutes I was on the road. Just a tip: you should really have sections of 1-1/2 pipe, male fittings and pipe primer/cement available for sale. I would have paid a premium to buy that stuff and not have to make a separate trip to the hardware store.
Anyway, got the gear home, followed the simple instructions, and had the new pump in and running within an hour. The old pump was a WAYNE, and I'm not sure how old it was. Pretty sure the check valve was last replaced in 1988... The new pump is MUCH quieter...can't even hear it run over the sound of the washing machine. And the valve shuts without the bang we had grown so accustomed to. I couldn't be happier with the whole experience.
Thanks again!

One Good One Bad
I had a Zoeller sump pump for nineteen years until the switch went wouldn't shut off. I figured 19 years was very good so I bought another. It lasted about eighteen months and then the switch stopped shutting off just like the first one plus there is major leak in the main seal between the pump blades and the motor. Is it worth getting either of them fixed? Should I switch brands? Or, is third time a charm?
SPD Responds: Replacing/Repairing sump pump parts has become a lot less common over the last 10 years. Pumps aren't made like they use to be and seem to have a much shorter life span. You might want to consider the "N53" because it requires a stand alone switch. The pump will typically outlast the switch and you can you a switch that suits your application.

Great Pump
My Zoeller M53 has been in my house for 17 years, I have lived here for 12 years, and still running fine.
I checked the sump the other day and it was full of water. But since it has a gravity drain also there was no flooding.
I pulled the pump out and it was warm due to a nail jammed in the impeller. The thermal overload feature saved the motor.
I removed the nail, cleaned out the sump and found 13 more nails and other junk, put the pump back in and it runs fine.
I will order another M53 cast iron pump as a backup since it is made right here in USA and a fantastic product.

Switch Failed After 18 Months!
We installed a Triple Safe Sump including two Zoeller pumps and a battery back up. After only 18 months the SWITCH on the primary pump failed. It clicks on and off, but the pump remains running. The repair person says they have not had good luck replacing Zoeller switches, but he would replace the entire pump if I wanted. My Sta-rite pumps always lasted 7-9 years and I never had a switch problem. If Zoeller is supposed to be the best why isn't their warranty more than one year?

Zoeller sump pumps are by far the best sump pumps Ive ever owned! Proudly Made in the USA! The M98s that I own are very reliable even after 2 years of daily use at my home, now the new 3rd one I just got (M53) is working daily also as my new 6 tier wine barrel waterfall pump, it has no problem keeping the water flow just right to make my water fall the talk of the block! Thanks Sump Pump Direct!

Zoeller M53
We were going 2 call a plumber but my husband spoke with his brother andn he said it would be easy...yea right. So we ordered the same model we had so that there wouldn't be any changes in the plumbing and it was as easy as 1, 2, 3. It was so simple a I could have done it. So listen up ladies if u have a Zoeller M53 save some money do-it-yourself.

Zoeller M53
Wow, incredibly fast shipping! Placed online order on Sunday night, and pump arrived around 12:00p Tuesday. Quick ship was a big deal for me as spring storms were in the forecast and this M53 was replacing a broken pump. After reviewing the quality and price of units sold at the local Orange Box, the M53 at $149 shipped was easily my best bet.
Little concerning that the unit arrived with one foot cutting clear through part of the manual, and the bottom of the box. Exact shipping issue is noted in another Zoeller pump review on this site. Anyway, I didn't see any obvious damage to the housing, float, electrical, etc., so I went ahead with installation.
Replaced a Zoeller Water Ridd'r that was part of my homes initial construction 10 years ago. Had to cut and glue a few pieces of pipe for the installation, but that was kind of expected.
Really like the 7.5" on point of this unit as opposed to 11.5" of pump I replaced. On point makes a big difference for me, as my drain tile pipe is located near the bottom of my sump pit. Now I never have standing water over the top of my drain tile pipe in the pit like with old pump.
Pump that was replaced weighed approximately 11 pounds, as opposed to the tank like 23 pounds of the M53. After testing my installation, with no changes to discharge pipe outside the house, I noted a significant new hole in the lawn where the water is being pumped. Guess that shows this new M53 unit is really doing the job!

Zoeller M53
We just refinished our basement and our current pump was 5 years old, so I thought it best to replace the old one, even though it was working OK.
My understanding is that sump pumps have a 5 to 7 year life span. I didn't want to regret trying to save a few bucks.
I had a great experience with Sump Pumps Direct and could not have asked for better service. I have already recommended SPD to two others and would personally buy there again.

I recently purchased a Zoeller M53 sump pump and Jackel basin and cover. I could not be more pleased with the quality and operation of both. The pump is heavy duty and looks like it will last for ever.

SPD Responds: For Zoeller Service Centers, please contact them directly @ (800) 928-7867
I am pleased with my new Zoeller M53 which replaced my previous m-53 and I hope it lasts longer than the original. The original m-53 was 4 years old and still pumps well but the switch only works intermittently. When it sticks the float came up but would not trip the switch. I would have to shake the pump lightly and it would pump. I would like to get the old pump switch repaired and use it for a spare if you could tell me where I could get it fixed. I like the construction of the Zoeller pumps and decided to give it another try.

I timed this purchase well- just 5 days after I installed the unit New Jersey had a severe rain storm...but my cellar was dry.
The construction of the pump is heavy duty and I expect years of service from this unit.
