Q: I just replaced my float for a Zoeller BN53-C...I noticed the wire on the float and the pump is brittle and deteriorating even when I strip the wire back 12 or more inches, is this common problem?. Can pump be rewired, and is there a rewire kit or do I need to buy a new pump? I want the same Zoeller pump but I do not need a new float as I just replaced the old float switch. Also, the new float is not kicking on, and my alarm is going off for high water. I followed the directions. Should I shorten its tether length? Currently it is at 4.5 inches from stack to float. I have a few more technical questions too can you contact me? Hope to hear from you TUESDAY 7/5. Phone:440-214-2047
by Paul Mihacevich from Ohio on July 04, 2016

A: Paul,

I would highly suggest reaching out to Zoeller directly. You can reach them at (800) 928-7867.

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 have a small catch basin aside my house with underground drain line that runs to the street. Drain line collapsed under sidewalk and with heave rain, catch basin backs up, overflows and I get water in my house. Thinking of putting this pump in the catch basin with a line out to pitched front lawn so when water reaches a certain level in backed up basin it will turn on and pump water out. Does that sound like a fit for this pump?
by Gary B from New York on June 06, 2013

A: If your catch basin is at least 18" wide by 24" deep, you might consider the Zoeller model M53 1/3HP Sump Pump or the 1/2HP model M98. The N53 model is a NON-AUTOMATIC pump and would not activate without the help of some type of float switch. The M53 & M98 both include a vertical float switch to activate and deactivate the pump. As long as you can filter debris like leaves and twigs from getting into the pump, you should be fine.
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: 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.

Zoeller N53
Pump shipped very quickly. Ordered some other parts from another site...weight 8oz took a week and a half. Received pump in 2-3days...made connections...plugged it in and its been working great. Pump has been good for far...looks like. Very solid pump...would give it 5 stars but I've only had it a month.. I'm confident though... will buy from this site again if needed.

Great pumps from Zoeller. I have 3. The first one lasted approx. 16 years in a sump basket.

Piece Of Mind
I have two sump pump pits in a sub basement. The pit bottoms are 13' below grade. After the last few storms, April/May 2013 it was time to replace my 10 plus year old pumps (different brand). I was starting to have problems with the float switches. I have help many friends that flooded after these heavy rains. Zoeller does make a quality pump. For control switch I use the "levelguard". No second thoughts about this setup. Levelguard has been proven to work more than 1.5 million on/off... more

Works Great!
I have had my new Zoeller N53 and LevelGuard switch installed for about a month now. I got them both installed one day before the huge spring rains hit, and I'm glad I did. I was replacing an older unit with an integrated diaphragm switch that was failing after 5 years. The new setup works great, and we got through the deluge with no water in the basement. The LevelGuard works perfectly as advertised, and the Zoeller pump is quiet and effective. Its solid cast iron frame also gives me... more

Zoeller Model 53 Sump Pumps
After extensive research, I determined the Zoeller 53 series to be the best sump pump available today.
Mine have always performed flawlessly in the worst of rain storms and beyond.

Off To A Good Start
Installed the N53 to replace a 4 year old RIGID pump. The float switch on that pump had failed and flooded our basement. The pump itself was all rusted out so I decided just to replace everything.

The N53 was delivered timely and the installation was smooth. The N53 is a good quality pump -- seemingly more rugged than the RIGID I replaced.

I installed it with a LevelGuard solid state pump switch and the pair work perfectly together. I feel good about using a solid state switch -- the... more

Zoeller Pumps Are The Best...
Bought this N53 sump pump to replace a similar (possibly the same model, could not read the model number of the old pump) Zoeller 1/3HP sump pump which lasted for 19 years. During that time, every Spring, the pump worked hard, turning on every couple of minutes and keeping our basement dry. It's a workhorse.There was no way I was going with a different brand. New pump is working great...

Most Reliable Residential Pump Ever
I just replaced my Zoeller pump that I installed back in 1997. It was still working, but the power wire was pretty brittle and I was concerned about its. Hope the new one last another 17 years.

Cast Iron Rocks
The previous pump had some kind of alloy housing. In two years, galvanic action had removed all the zinc from the housing and it ended up with a fist size hole in the side.

The Zoeller is mostly cast iron which galvanically is more neutral than zinc alloy. It might show a bit a slight bit of surface rust, but I am sure I will never see it rot like the one it replaced.
Pros: Quiet, Price, Durable, Reliable
Cons: Bad Instructions, Packaging

"Only one minor issue. The box is not study enough to ship the heavy pump. I've bought two of these from Sump Pumps Direct, and in both cases the box looks like shredded wheat when it arrives. I guess the self destruction works because the pumps survived just fine, but it is a bit worrisome when a new product arrives in a underwhelming package."

Pump Received Was Damaged
My plumber opened the box to install the N53 and LevelGuard switch only to find that 1) the pump handle had fallen off the pump because it had somehow spread, and 2) the power cord was severed almost all the way through. We tightened the handle to the pump using a C clamp. The cord cut about a foot from the pump, so the plumber offered to re-wire it after removing the cover, which added a half hour of time to his labor charge. I didn't want to have to have him come back a different time and... more

Great Pump And Easy To Order
Thank you to all who did reviews prior to me, it made me much more educated on making the right choice. The Zoeller N53(no switch) with the Level Guard is the way to go. Easy to install and runs perfectly as well as super quiet. So far 3 people have taken pictures and will be moving to this combo.
Pros: Quiet, Durable, Price, Easy To Use
