  5 Questions
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.

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.

Great Pump At A Great Price!
I've installed many of these pumps through the years and they are ALWAYS reliable and perform as expected. I paired this non automatic Zoeller pump with an electronic switch to ensure the pump will last for a very long time.

Great Customer Service
We ordered the N53 and paired with electronic level guard sump pump switch. I like the idea of a well-tested electronic switch to engage the pump rather that having to worry about a mechanical lever failing. I'm by no means a handyman, but the install was simple. I needed to go to HD to buy a 1.5" male adapter, and some PVC cement, but that was it. I initially wanted to buy a 1/2hp pump, but since we don't have a huge amount of water in the drain even during bad rains, and because we only... more

"First pump was damaged in transit. Sump Pumps Direct was very easy to work with through email and phone. They scheduled a pickup of the first pump (and subsequent delivery of a second pump) ASAP. I expect this pump to last a long time, but I have no reservations about ordering from them again when the time comes."

Great Pump
This is a good pump without the built on switch like the M53. The pump will last for years but the M53 switch will not last over 2 years. I bought a separate switch to use on the N53

Well Worth The Cost
Although I purchased the Zoeller model N53 and the Level /Guard sump pump switch, It took me about one month to find the time to install it. I've installed both and tested them. The pump and electronic switch tested great. My wife was shocked that the whole operation was so quiet. I also purchased the quiet check valve and that is also very quiet. The product arrived in good shape and on time. It's too bad that I've been so busy that I had to delay installation. I trust the system will... more

Gold Standard Of Sump Pumps
I have a very active sump. Runs about every 15 seconds. I have iron ochre. This is the only pump (combined with an external electronic switch) that lasts more than a year. The last one i got about 8 years out of it. In my previous house where the pump ran about 2-3 times a day, these would last 15 years before failing.
Pros: Quiet, Durable, Reliable, I'd Buy It Again
Cons: Expensive

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
