Q: Jim,

I currently have a 1/3HP pedestal pump discharging through a 1-1/4" pipe. My pit is 15" across by 24" deep. When it rains, my pit fills up very quickly and the pump goes every 2-3 minutes. I want to replace it and was looking at this pump because my existing one is old and noisy. My concern is that it will be going off even more often if I change to a submersible style pump because it sits lower in the pit. Will that be the case? I don't want it to have to run more often then it does now.

by Karl D from New Jersey on October 01, 2014

A: Thank you for your interest in Sump Pumps Direct. One of the advantages to pedestal pumps is that you have the ability to adjust the float switch to allow the pump to evacuate more water out of your pit per cycle, thereby reducing the number of cycles per hour. Introducing a submersible pump like the Zoeller model M53, should give you a quieter pump but it may very well cycle more frequently than your current 1/3HP pedestal. One option you could look at to overcome this, would be to install the non-automatic version MODEL N53. You could then install a separate electronic switch like the Pro Series Ultimate Sensor Digital Pump Controller System, model USC3 or the HydroCheck Electronic Hi-Lo Pump Switch, model HC6000. These "piggyback" style switches will give you the ability to fine-tune the ON/OFF levels for your pump operation.

Q: My Zoller pump has a threaded female connector on the body. What am I expected to put between the pump body and the bottom clamp of this check valve?
by BN from California on September 17, 2014

A: Typical installations will include the discharge PVC Sch40 pipe screwed into the pump discharge port and extending approximately 2-3 feet above the sump basin cover. At this point, you could attach the check valve and then complete your discharge configuration. This method would allow for an easier access point for you to service your pump.
by Jim, Product Expert
Q: I plan to replace a non working Zoeller M53 in a recently purchased house with a new Zoeller M53. Two questions: 1) the current set up uses 1 inch PVC discharge pipes - up about 8 feet and then horizontal for another 15 feet until exiting the house. Is the 1 inch pipe OK, or is it necessary to change to 1 1/2 inch pipes? 2) what is the recommended location for the new check valve? I was planning to go about half way up the vertical pipe. Thanks, Jim
by Gene from Missouri on August 24, 2014

A: Thank you for your interest in Sump Pumps Direct. The discharge on the Zoeller M53 is 1-1/2" and as such, you should resort to that same size piping to achieve optimum performance and pumping capacity. If you must reduce the piping, I don't recommend that you go any smaller than 1-1/4". Reducing it further will only create more backpressure on the pump which will reduce the pump life, not to mention the reduction in pumping capacity that you would realize.
The check valve placement can be anywhere from the discharge port of the pump to about 2-3 feet above the sump basin cover. The latter is my suggestion as it also allows for a good place to gain access to your system for service.
If you have additional questions, please let me know.

Q: I am thinking of buying the Zoeller M53 - 1/3 HP Cast Iron Submersible Sump Pump w/ Vertical Float Switch.
But I was wondering does this need more than a 15 amp outlet, due to start up amps?

by Bill from Maryland on March 01, 2014

A: All sump & sewage pumps need to be wired according to national electrical codes and all applicable local codes and ordinances. When in doubt, you should contact a licensed electrician in your area.
Pumps are not to be installed in locations classified as hazardous in accordance with National Electrical Code, ANSI/NFPA 70.

Q: Installing an underground sump pump to drain water coming under the house. Was thinking about ordering the following kit, but I am not sure if the basin is the correct one for a sump pump or if we should switch it to something bigger.
Zoeller 1050001 13 HP M53 Remote SinkDrain Pump System w Vertical Float Switch

Thank you,
Nestor Ho

by Nestor H from Texas on October 21, 2013

A: Thank you for your interest in Sump Pumps Direct. It really depends on how you plan on getting the water into the sump basin. If you are doing a typical basement INSTALLATION, I would advise something more like the Zoeller model M53 or M98, depending on your water table. I would then suggest installing a standard SUMP BASIN and COVER. You can then tie this in to a french drain or you can drill holes in the basin to allow the water to seep through and into the basin for discharge by the pump. If you are looking to install this system outdoors or in a crawl space, the Liberty 1/3 HP Cast Iron Crawl Space Sump Pump Kit, model CSP-257 might be a better choice.
And don't forget the CHECK VALVE.

Q: I have a Zoeller sub pump 1198 horizontal install, I would like to buy another pump,where this one is quite old. What is the model # I should buy. There is no info on tag that is attached the plug wire. I want to say this pump is at least 30 years old. I have never replaced it. Could you please tell me what I would need to purchase. I don not have any owners manuel on product all I could find was 1198 horizontal Install on pump. Can you please assist me.

Thanks,
Rebekah

by Rebekah T from Massachusetts on June 14, 2013

A: Zoeller basically builds 2 models, the 1/3HP model M53 and the 1/2HP model M98. The 1198 number most likely refers to the date code. If you cannot locate the model number in the same area as the date code, the 1/3HP model is about 10" tall and the 1/2HP model is about 12" tall. I would also suggest replacing your CHECK VALVE as well.

Q: I have a M53-D Zoeller pump that is about 10yrs old.I was told by my home builder that it was rated to pump vertical up to 10ft.is this true?I have miss placed my owners manual and now the switch is bad so that the pump runs constant till it over heats,is that do to pumping vertical for 10yrs out of my basement for a washer?By the way it has been a great pump and will never own anything but a Zoeller for the rest of my time.Thank you.
by Darrell A from Virginia on April 20, 2013

A: The Zoeller M53 is and has been a great pump for many years! It is designed to handle a maximum of 15 feet of vertical lift. I have heard of this pumps lasting for 10, 15, 20 and even up to 30 years. Chances are that the switch has failed and needs to be replaced, which is a common occurrence. We do offer the Replacement Mechanical Switch for M53 and the Zoeller Complete Cover Assembly & Switch Kit For M53 Sump Pump. Please note however that the switch requires installation by you or a certified plumber/contractor and ALL SALES ARE FINAL - NO RETURNS ALLOWED ON THIS PRODUCT.
by Jim, Product Expert
Q: Should the switch compartment of the M53 remain above the waterline or be watertight, because when i opened to determine if i should replace the switch a lot of water came out. All the terminals are corroded so it's been running like this for some time. I'd prefer to bypass the switch altogether but not if the compartment can't be sealed properly.
by Steve from Wisconsin on April 20, 2013

A: There is a rubber gasket between the switch housing and pump housing that form a water-tight seal to protect the switch connections. If water has seeped into the switch housing, this would certainly compromise the performance and safety of the pump and I would highly recommend replacing the pump. Under normal operating conditions, it is NOT uncommon for the pump and switch housing to be completely submerged.
by Jim, Product Expert
Q: Jim what is the difference between a m53 and a m57 zoeller pump
by Garver from Illinois on February 11, 2013

A: The M53 has a cast iron switch case, motor and pump housing with an engineered thermoplastic base and an engineered, glass filled, plastic impeller with metal insert where as the M57 is all cast iron construction including the impeller. Other than that, both pumps are the same.
by Jim, Product Expert
Q: What does min. sump basin size mean?
by John D from Massachusetts on February 02, 2013

A: The minimum sump basin size relates to the minimum size of your sump basin or pit, that a specific pump will safely operate in. Any pump needs a certain amount of space due to "on/off" levels, cooling factors and cycling that the pump is designed for. Most pumps will require a standard size basin of 18" wide by 24" deep but some will also operate in smaller basins. You want to pay very close attention to these requirements as they will insure a longer pump life.
by Jim, Product Expert
Q: I have a Zoeller M53 1/3 hp sump pump. It is at least 7 years old. I think older. It has been running well, but now it will not come on. the float is free and clear, but will not kick on unless i just tap the arm. The the pump works fine. I have cleaned the pump, well and float. Do I have to replace the pump?
by Stephen from Delaware on February 01, 2013

A: The normal life of a sump pump is about 7-10 years, though I have heard of some going 10-20 years and more. Zoeller pumps are known to last but are also known for some switch problems. Please note that all manufacturers do recommend that you inspect your pump and basin every 3-6 months to insure that they are working properly. That being said, you can make the call on weather you would like to replace the pump or the SWITCH. If you decide to replace the switch, please be advised it would require installation by you and ALL SALES ARE FINAL AND THERE ARE NO RETURNS ALLOWED ON THIS PRODUCT.
by Jim, Product Expert
Q: Is any maintenance required on the M53 pump? I see there are two white plugs on the pump and I'm wondering if oil needs to checked or added periodically or any other type of maintenance is needed.
by Jim M from Nebraska on December 22, 2012

A: The only maintenance that is required is what all manufacturers recommend. And that is to inspect your pump, float switch and sump basin every 4-6 months to insure that they are operating properly and there is no debris in your basin that could impede the pump or float switch operation. Oil should NOT need to be added at any time unless the pump develops a leak which is pretty rare. If that should happen, it's usually easier to have it serviced at a local authorized Zoeller service center or replace the pump.
by Jim, Product Expert
Q: What locations in Anchorge sells your product. I think only only one model m53 can be ordered through Sears.
by Ef from Alaska on December 11, 2012

A: Unfortunately, I would not have the answer to that question. We are an online retail store that sells and ships many different brands of pumps all over the United States. We are based in Bolingbrook, Illinois and only operate out of this single location. You might try looking at our listing of manufacturer contact PHONE NUMBERS to find the manufacturer of the pump that you are interested in and then calling them for assistance on finding a local dealer.
by Jim, Product Expert
Q: I am getting a portable generator and want to include my zoeller m53-d pump to be one of the items supported by the generator. What kind of draw (startup and normal operation) should I include in my calculations for sizing the generator. Note, in hurricane Irene my pump was going off every minute.
by John B from New Jersey on November 04, 2012

A: While the Zoeller pumps are one of the better pumps out there, they are not very efficient. The M53 runs at 9.6 amps and requires 25.9 amps to start. When using the formula of amps X volts = watts, you would need a minimum 1152 running watts and 3108 starting watts to operate your pump. When using generators, you should never load them up any more that 80% of their capacity at any time, so you might consider a generator with about a 4000 watt starting watt capacity.
by Jim, Product Expert
Q: I purchased a home with a zoeller sump pump already installed in the basement. Is there any way for me to tell whether it is a 1/3 or 1/2 hp model? I need to buy a generator, so I'm trying to determine what size. Thanks
by Mich from Tennessee on November 03, 2012

A: There is usually a brass tag mounted on the top side of the pump between the the power cord relief and the float switch arm that will give you the model number and date code in addition to the voltage and amps. If that is not visible, you can measure the height of the pump. The 1/3HP model is just over 10 inches tall and the 1/2HP model is just over 12 inches tall.
by Jim, Product Expert
Q: I would like to know how many watts a 1/3 or 1/2 hp sump pump has, because i was think of buying a portable generator in case the power goes off.
by Tom B. from New York on September 03, 2012

A: That really depends on the pump. Some are more efficient than others. For example, the 1/3HP Basement Watchdog model BW1033 has a running amp rating of 3.5 and a starting amp rating of 7. When you figure the watts by the formula of amps times volts equals watts ( A X V = W), you get 420 running watts and 840 starting watts. But when you look at the Zoeller 1/3HP model M53, that pump has a running amp rating of 9.6 and a starting amp rating of 29.6 or 1152 running watts and 3552 starting watts.
by Jim, Product Expert
Q: What kind of warranty do you have on your pumps?
by John from Pennsylvania on July 03, 2012

A: Pump warranties vary from 1 year to 5 years depending on the pump and the manufacturer. That being said, all pumps should last a good 5-7 years or more providing they are installed properly.
by Jim, Product Expert
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.

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: 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.

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.

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.

Direct Replacement
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... more

Beware Of Ice Blockage
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... more

William,
7 to 8 yeas of pump life is actually pretty good for pumps these days. Ice Blockage can be contributed to how the discharge is set up on the exterior of the home. No matter what pump you're using, if the discharge is not set up correctly when it exits the home, ice blockage can occur. Sump pump are not designed to pass large pieces of sediment.

Pump installation instructions were clear. Pump works as expected. Appears to be a quality item. Time will tell.

A Flush,beats A Full House
Needed a new sump pump, to keep the basement from flooding twice in one month oopps, what to do hhhhmm. Buy a new sump pump, that actually works and has a reputable reputation, so I followed the advise of my septic guy, get a Zoeller, have one in the other crock, worked good until ballast contact switch went out, called Zoeller, told the tech what was going on, he diagnosed the problem over the phone, sent me a new switch at no charge, cant beat that.. so now you have a customer for life.... more

I had trouble with water backing up through sump pumps. They did not work well at all. My new pumps from Sump Pumps Direct fixed that problem.

Thanks guys for my two Zoeller M53-1/3HP cast iron sump pumps w/vertical float switch. The other pumps I had have been replaced twice in ten years and were going out again. Your pumps came highly recommended by an insurance man and a plummer friend.

High Quallity, Long Term Reliability ?
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... more
Pros: High Quality, I'd Buy It Again, Easy To Use

3 Of These In 10 Years
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.
Pros: Easy To Use, Quiet
Cons: Expensive, Low Quality, Durability

Gene,
You may consider the N53 (Non-Automatic M53) with a LevelGuard Switch. You don't have to worry about the durability with the built-in switch. The LevelGuard switch is about as durable as you can get.

Quality Sump Pump
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.
Pros: High Quality, Durable, Price, Reliable
Cons: A Little Noisy, Pulsates At Times When Off

Best Experience!
Sump Pumps Direct was a pleasure to do business with. They were knowledgeable, efficient, and filled my order quickly. They confirmed the order and shipped my pumps within 24 hours.

A day later, I received my pumps. Shipping was free (even though each of the two pumps weigh about 15 lbs). Great experience.
