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

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.

Works great

Excellent sump pump. Reasonable price for the unit. Quieter than my past pump.

i have purchased two of these, the first one lasted 12 years, which is great , i have now had the second one for two years and works great . zoeller is considered buy many professionals as the best sump pump you can get. yes they do cost more, but as the saying goes, you get what you pay for. i would recomend having a professional installing it. or someone that knows what they are doing, if they are installed wrong they will not work right .

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.

Not much to say about this one. I've owned 4 Zoeller pumps and will never buy another brand. These things simply work, they're super reliable, and product support was fantastic on the 1 occassion I needed to contact them about an out of warranty pump. They are worth the money!

Bought a new house which came complete with some drainage issues and a sump well. This make and model of pump had been placed in it but at some point someone had attempted a repair on it and it was now ungrounded and happily electrifying all the water any time it ran. Unfortunately the repair attempt had made the old one pretty much unfixable, which is a shame because I understand from reviews and recommendations that this is a solid workhorse. Given that, and the fact that all the plumbing was already made for it, I ordered this replacement and never looked back. It's generally quiet enough that I have to check outside to make sure it's running. Seems like we haven't even come close to exercising the capacity and the flow rate is more than ideal. Now I can feel confident that we're not going to get flooded out, and at the same time not worry about being electrocuted too.

Tres Bonne qualité facile a installer

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

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.

Full retail package, took 5 minutes to install out of the box and moves more water, faster and quieter than my 1/2HP pump. Bombproof design. Highly recommend this version over the builder version.
