Zoeller 53-0002 N53 Mighty-Mate Non-Automatic Submersible Pu

Pump works great and is very dependable.

Compact and more than powerful enough for my sump requirements replacing my failed Big-Box 1/2 HP unit. Reliable big name manufacturer with good warranty. Additional draw for this model is that it's built with no internal float switch: Previous other manufacturer units I've owned have internal float switches which failed before the pumps failed, requiring me to install external sump controller switches (not expensive) which made trouble shooting much easier. Why gamble and pay extra for an internal switch if you might end up replacing it with an external switch later? Solid unit, easy install and good advice from manufacturer's help phone line when necessary. It's worked flawlessly for a few months, which obviously doesn't yet tell me anything about long term reliability. But it seems like a more powerful and better built unit than the last two, which each lasted about 10 years.

If you want a set and forget type sump pump, the Zoeller 53 series is arguably the best option, ASSUMING THAT YOU GET THE CORRECT CONFIGURATION. There are endless reviews of 53 series pumps with built in vertical float switches failing prematurely because the built-in float switch failed. There are almost no reviews indicating that any other part of the pump failed prematurely. So by far the better option would be to get the non-automatic version of this pump and equip it with a tethered piggyback type float switch, making it automatic, but also eliminating the primary cause of this pump’s failure—the built-in float switch. Less is more with sump pumps—rugged simplicity rules. Tethered piggyback float switches have decades long track records for reliable function. Built-in vertical float switches much less so. If a piggyback float switch fails you can still use the pump in an emergency by plugging it directly into an outlet. And you can easily replace a defective external float switch without touching the pump. If for some reason you don’t like tethered float switches, you can still use a non-built-in piggyback vertical float switch that mounts to the sump’s discharge pipe rather than being built into the pump itself. This also would be a better option than a pump with a built-in float switch. The one con? Zoeller makes a heavier duty version of the 53 series pump called the 63 series that has a cast iron impeller, a cast iron base, a lighted plug and a longer warranty. But they ONLY make the 63 series with a built in float switch. I wonder at times if Zoeller promotes its pumps with built-in floats because the pumps fail faster and that way Zoeller sells more pumps. Be that as it may, the 53 series pumps with a Zoeller or a PumpSpy tethered float switch is the best current solution for a reliable and long lasting 1/3 hp sump pump.

VERY HEAVY DUTY PUMP WORKS BETTER THAN MY OLD 1/2 HP

Works great
