Top of the line pump. Our plumber has installed dozens without problems. They last for years. They run pretty quite. The pump rate at full open is above 15 gpm, enough for any washing machine and sink together.

Works perfect and is nearly silent. Only issue I had during install was the vent I bought from lowes only allowed air in and not out. For this pump to work the air must be pushed out the vent to allow the water to flow into it. A couple drill holes on top of the vent fixed that. Otherwise the pump is flawless.

I used this pump under a utility sink, plumbed into an existing drain outlet, and it is working great. Plumbing couldn't have been easier and in fact I hadn't done any plumbing previously, but it went great, no leaks, and works well. The only point I'd make is that this unit requires venting and based on the suction at the vent, I tend to agree with the instructions that a "cheater vent" or Air Admittance Valve wont work. This means that if you don't have a conventional vent solution, you will have an open vent - which may or may not be an issue. For me, our washer drains into the utility sink and when the pump gets enough water, it pushes the water up and out into a grey drain outside. Sometimes though, the water that sits in the pump can get a smell to it and you can, at times, smell it from the vent when the pump kicks on. This doesn't happen that often, and if you were to rinse with clean water after the washer drained, it would never be a problem. Its not really an issue for us, certainly not enough to worry about it, but something to consider based on your application and installation location.

Works great so far, regulated flow down with a ball valve , this was amazon warehouse deal returned item, looks new box was retaped no fittings were ever screwed into it, huge money savings over" new "one

This is a really good pump. We built an addition on our house for my sick parents and it included a kitchen. The builder was not able to tie in to the existing plumbing without adding this pump. I would pull the pump every 6-8 months and pressure wash the inside to remove the buildup that, if I did not clean it, would cause the float to stick. Had the first unit 10 years and just replaced it with the same unit. I kept the original as it did not have a problem but I felt it was time for replacement. Liberty makes good stuff!
