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

The media could not be loaded. 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.

The best sump pump money could buy! I've used it since 2010. Now it's 2025 and it's still running great. I'm buying another one as a backup.

Zoeller is the top of the line go to unit for sump pump installations. The heavy build and reliable operation is second to none. I would not put anything else in my sump pit, which is critical to keeping water out of my basement. Runs quiet, plenty of power without using too much electric and i know i can rely on this for many years to come.

This is the third Zoeller that I have purchased in 30 years. The other two are still running. This was replacing the second sump in the house.These are very well made pumps that aren't fancy, but they work. And for me that is the most important quality a sump pump can have.

This thing seems like a beast so far. My basement flooded a few months ago so I replaced my old sump pump with this and I've had zero problems since, even with worse weather and several flooding events. It's not the cheapest, but you get what you pay for, and this thing certainly does the job well. Easy to install, functions well, and has an excellent flow rate.

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.

Replaced a cheap and non practical pump with this one and boy is it powerful!Worth the extra $

This was an older purchase.The pump is great,never had a problem and is well made.
