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

Works well and so far so good

This pump is a great product.It worked perfectly with my new Rheem hot water heater.

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.

These are NOT 3/4" pipe fitting thread. I have no clue what size is there because I was never able to find anything other than a 15/16" gas line flare fitting that would thread on. If you were hoping to put pump flanges on these or even thread up valve on to the end of these pumps then you are out of luck.

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!

I used 500 ft of black irrigation hose on the ground and put this pump in the loop to and from my pool. I also installed a christmas light timer so that it ran only during the sunlight hours. It made the discharge water almost too hot to touch. It works great for the price!

The pump arrived with cardboard packaging not covering the pump. Packaging was floating around loose inside the plastic shipping bag and the pump was scratched in several places through the red paint. That said, the pump works well so far but it's only been hooked up for a week. This is my 2nd response. I've just received my second pump because I wanted to have a spare. The first pump is working perfectly. It's runs 12 hours a day. If it should ever fail, in the future, I'll just install the spare.

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...
