Zoeller M53 Mighty-mate Submersible Sump Pump, 1/3 Hp

I had on at my old house that was installed by the previous owner. It was quiet and worked great. I Bought my current home in 2019. They had a sump pump from Lowes that worked but it was the loudest thing ever and it ran all the time. I got tired and purchased this May 2020. Almost 6 years later it is still running like a champ. It operates quietly and when it runs its only a few seconds and back off. This thing runs a 1/3 of the time of the one I replaced. If / when this one fails, I will replace it with this same unit. Again, the review is being written almost 6 years after I purchased it.

Real easy to install. Cord is plenty long enough. Works great. Always use a check valve..

I recently installed the Zoeller M53 Mighty‑Mate Submersible Sump Pump in my basement sump pit, and it’s been doing a great job keeping water levels down. The cast-iron body feels rugged and high quality, and the automatic float switch reliably kicks the pump on when water rises. The pump moves water efficiently and quietly — I barely notice it running even during heavy storms. What I like most is the build quality and the peace of mind: stainless-steel hardware, corrosion-resistant finish, and a design tested for longevity — it feels like something you install once and forget about for years. If you want a no-nonsense, durable sump pump that handles everyday water intrusion without fuss, this one hits the mark.

I have had a zoeller pump in my crawl for almost 20 years with no problems. My spouse was replacing his Lowe's pump every year in his rental. It could have something to do with the disintegrated check valve, but nevertheless, every year the pump would go out. This time the crawlspace filled up. So, I bought this pump, and the zoeller check valve which is amazingly built to last, and drilled a ton of holes in a five gallon bucket, bought cheap plastic hoses from Menards and connected them so that they would reach to the sewer ditch in front of our house (about 200ft). I put this pump in the bucket and lowered into the crawlspace and it pumped the entire thing out in less than a day. It required some supervision to make sure the float didn't get stuck, and I had to hold the float up when the water was getting low and not rushing into the bucket as fast, but it worked beautifully. You will burn a pump up if you leave it running without water flow so you must watch it. It is quiet in comparison to the last ones, and doesn't vibrate the whole house. It's extremely powerful as well. We have gutters that drain into our sump pit so our pump works a little more than others. This thing is amazing. It's only been a few months, but the quality was immediately noticable. DO NOT BUY HOME IMPROVEMENT STORE PUMPS OR CHECK VALVES. I reviewed the zoeller check valve as well and it's such great quality. I'll never buy another brand. Instead of rubber insides, it contains a large, metal flap. This pump is less than I paid for the Lowe's pump last year. Do yourself a favor and get zoeller products.

I have hade several of these sump pumps. My home has two sumps so I need two pumps. The pumps themselves are very good quality. They last at least 5 years. HOWEVER, I have had issues with the switches that are part of the pump. They tend to fail before the pump motor. In my case, the switch failed stuck in the ON position. So I bought an external switch such as a float switch or an electronic one (electronic ones are MUCH easier to adjust). Plugging the pump into the external switch extends its life by several years. You may be able to get this pump without a built in switch and save some money and avoid the switch failure. Note the switch failure happened to BOTH my pumps.

The pump arrived when promised and works well. Because it was part of an AC/DC combo set, there was some finagling that had to be done to get the piping correct. We ended up having to install a new flow control valve to make the system work.

I replaced mine after eight years because we were having a lot of water, but It still ran fine

Amazing!! I ordered this pump on Wednesday afternoon, and it was delivered by UPS on Thursday afternoon... WOW!!

Se descompuso a los 6 mese de uso y no puedo hacer valida la garantía en México porque el producto es de importación

So far, so good. This was a DIY project by a non-plumber, and I’m really happy with how it turned out. I’ve already run 6 test cycles perfectly. It’s quiet, fits perfectly in my 12x12” sump pit, and the float seems to be working great. Highly recommend.

Tres Bonne qualité facile a installer

Supper easy to install. Built like a tank. Pumps a huge volume of water very quickly. Have had it now through three heavy storms and it does its job really well. It is also much quiter than my last sump. To the point I went down and made sure it was working. My old one you could definitely hear it downstairs turning on. This on is much quieter.

The most recent one purchased contains a light incorporated in the (plug in) which help to know if the electricity is on.
