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.

Excellent pump. Replaced an identical one that lasted 20 plus years.

This was the exact same model sump pump installed in my house nine years ago. Very easy to swap them out. And it’s running great.

I bought this in December of 2014 for my basement. I m writing this review after 10 years of use. This pump is still working perfectly. Don't look anywhere else, if you want a quality sump pump.

Bought a new house. Inspector flagged the sump pump as having a faulty float valve and generally looking tired. Sure enough, less than 6 months in the house and the old pump seized and popped a breaker.When my inspector flagged this issue back in the fall, he recommended a Zoeller for a replacement. So I jumped on Amazon and grabbed this one. My inspector has seen hundreds of properties, and he has lots of experience. When he recommends a brand, I almost always go with his suggestion. Based on the review for this item, sounds like everyone agrees that Zoeller is quality.For what it's worth, I replaced an Everbilt, which is not much cheaper, but definitely seems like a much lower quality.Thankfully, I was able to use all of the existing parts. It took some effort to clean up the PVC threads from the old sump, and then I added some pipe dope for good measure.Per the instructions, I added a 3/16 hole to prevent air lock issues. MY PIECE OF ADVICE - drill the hole pretty close to the threading, and angle it downward. My first hole (which I patched) was inside my crock, but not angled down enough and too high. The first time the pump ran, it shot water everywhere as the pressurized stream from the air hole hit the side of the crock and splattered. Patched the hole, pulled the pump, and drilled a fresh, lower, and better angled hole. Still a little splatter, but it's fine with the sump lid on.My only complaint - the item arrived having previously been opened, but, as far as I can tell, unused. I'm guess this was an Amazon return that Amazon decided was good enough to sell new again. It looks like someone got this item, opened the box, determined, for whatever reason, they didn't want it, and then sent it back. That being the case, I was comfortable with keeping and installing what I received. Happy to not create unnecessary costs with a replacement request. (Good for ole planet earth too).Anyways, 5 out of 5. Can't speak to longevity from personal experience, but very pleased so far!

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.

This pump was installed 4/29/2013. And is still running as I write this. Never a problem, not even a switch. Most will say average life of a sump is 8-10 years. Well, I guess 12 and still running is great. I bought another exact model. It's on stand by for installation. Gonna see how long the original will last yet be ready to replace.

great unit got the job done
