3/4" NPT 110V Hot Water 3-Speed Circulation Pump Circulator Pump

Installed on a vertical cpvc return line next to the water heater. Was uneasy about the weight being supported only by the cpvc, so added a support arm to an adjacent shelf to hold the weight of the pump. Plugged it in and waited a few minutes -- no hot water at the far sink -- then remembered that I needed to bleed the air out of the pump... Voila!! HOT water!! Did have a little trouble tightening the bleed screw enough to stop a drip, but did succeed. Runs so quiet that I have to touch it, (or the pipe) to feel a slight vibration. Plan to add a mechanical plug-in timer, so it won't have to run 24/7. Hoping it will last for years.

This pump seems to work just fine. Took a minute to prime, but reading the instructions may have helped. I use this daily to circulate cutting fluid in my plasma table, with no issues. It does have three speeds, and plugs into a standard 120v outlet.

Pump froze up in under 3 years. Lightly used during that time. Granted it’s a cheap pump. I got what I paid for.

After being blown away at the current prices for a grunfos or taco, these have worked fine for a couple of years now. Maybe it's because I bought a spare...

Too loud. Always hot, afraid it’s going to burn all the time, but it doesn’t

As a master plumber this is a good one. Much cheaper than the brand name ones.

Pump works great! Unfortunately the hose fittings are much larger than what is described in the listing on Amazon, causing me to have to got to the local home improvement store for the correct size. 3 stars as a result!

Cost was less than comparable units. Fittings were included. It's working well.
