Superior Pump 91016 Thermoplastic Oil-free Utility Pump, 1/6 HP, Black

Excellent simple design works every time I use it for the last few years. I've used it to pump water out of our rain collection system and to cycle vinegar through my water heater and works phenomenally well.

Nice pump for flushing on demand hot water heater (Rinnai model). Worked perfectly for circulating 4 gallons of 5% vinegar through the water heater for an hour.

Purchased this Superior Pump utility pump to empty out our kiddie pool, was tired of standing on the edge of the pool to drain. Pump works great and I liked that it came with a garden hose adapter. Pump is quiet, easy to use and made draining the pool so much faster, great pump.

I bought this pump to flush/descale my tankless water heater. It works as intended.

Pump had a lot a pressure at first, After a few weeks, the pressure dropped even being inside a 5 gal. bucket with filter material. The water is still clear. I'll take it apart and check the filter material, but I think it's that the pump is gradually getting weaker.

I use this pump to flush my tankless gas water heater. It is perfect hp. Just sit in a 5 gallon bucket with hoses going from pump to heater and from heater to bucket for recirc. Perfect flow to remove the scale. Strong housing and cord protection

Used 1 time so far for my tankless hot water heater ( flush ). Worked well no issues.

So far I am very pleased with this unit. I plugged it in the first time today on my flat roof and it worked fine. Pretty quiet, but you can hear it running. If I had it to do over again I would have bought the model with the slightly bigger motor.
