Zoeller 53-0002 N53 Mighty-Mate Non-Automatic Submersible Pump, 115V

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.

Pump works great and is very dependable.

This pump is QUIET and solid! If you've been using those light weight .5 HP pumps you get for about $80 at a local box store and have had to replace them every 3-4 years make sure to really check out your setup!Our pumps kept dying, either the switches, motors or, in the case of the last one, the casing. Yeah, the casing! From corrosion, and repetitive hits from the startup torque. It was a FloTec FPOS3250A that had already had its switch break and replaced. It was only 3.5 years old.This new unit doesn't display any external evidence of torque; like exit pipe jarring or shaking. And it is dead quiet! With previous pumps you could hear the hum, then the 'sucking' as it got to the bottom. It was so loud you could hear it from the basement to the main part of the house, with doors closed, when nothing else was going on. I can't even tell the Zoeller has cycled, standing right next to it, without watching the water level.We have a 24" deep sump and this Zoeller unit is being paired with a piggyback floating switch, and after a bit of adjusting it turns on right at the top of the sump pit (1" below the intake and 2" below the Watchdog Water Alarm) and turns off right where you'd get water streaming out of the pump vent hole (~ 3"), for ~ 20" removeable water. Compare that to the 7.5" of travel from the 'plunger' style float. The .5 HP FloTec emptied its water in ~8 seconds and the .33 HP Zoeller now uses ~46 seconds.It seems the main culprit of our pumps dying is 'short cycling', during the wet season the pump would cycle on every few minutes. We haven't had a good test for the Zoeller yet, but timing using a fully open faucet took ~9 minutes. So, 9m + 46s (~6 starts per hour) versus 2m + 10s (~27 starts per hour). I can't blame FloTec for me not doing the math earlier.Originally I was going to replace this with the updated version of the last one (like the ones before; because ~$80 is way less than $140) but decided to go for it and if this unit lasts 4-5 times longer it will have been well worth it!

Works great

My local hardware stores only had low-quality pumps that cost more than this one (they are big stores too!). Zoeller's a good brand, so happy to get it here for cheaper. Just picking this up you can feel the quality. Almost all cast-iron, weighs around 30 pounds. Make sure you drill the weep hole low in the basin, since this pump is really powerful. Easy to install, works like a pump should.DO NOT get the automatic version of this or any other sump pump. You do NOT want an integrated switch system. When the switches fail (and they do, often), you need to be able to pin point the problem quickly and replace the necessary part. Get an electronic piggy-back switch that this pump can plug into. They are more expensive (about $80) but last over 10 years as opposed to 2. You don't want a switch going out on you during a rainstorm.
