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

Is working. Thank you

Easy, straight forward installation.......it is as quiet as described...NO LEAKS (I used tape and plumbers putty).Must buy Sensor Valve for it too work, which I did

100% junk. Can't handle heat

First, the instructions are not easily understood by a non-plumber. Second, there was discolored hot water that came out the first couple of times it was used. Third, a few days later some black flakes came out of all our hot water taps. Not a lot but disconcerting to see. I had to clean the flow restrictors on our sinks as they were full of junk. After a week the discoloration and black flakes have stopped.

Todo Ok

Update:I use this pump to circulate water through 500ft of 1/2” poly pipe in a homemade solar water heater and even with the pool water 3’ above the pump inlet it has never performed satisfactorily but this year I put this pump on 500ft of 3/4” poly pipe and it is working like a champ. Not sure why it quit pumping in prior review but after inspecting the impeller it is working fine. It’s all cast iron design means it does rust and I take some care when it goes into storage for the windows. As in all these cheaper pumps you must orient them to keep the electric stuff above the pump. The fittings are for garden hose thread but brass adapters are included to convert to 3/4” pipe thread. I think these adapters are NPS rather than NPT but with enough thread sealant they are working for me.Original review:Used about 4 hrs per day for 6 months as circulation pump for solar heater for above ground pool. Never ran dry as about 3ft head on the suction side. Its output has dropped to nearly zero and net head is about 1 ft now so basically useless after only 6 months. Additionally:- input and output threads not well made. Took Teflon tape and extra rubber washers to get tight seal.- impeller mysteriously jammed one time. No debris that I could find. There is a removable plug to grant access to impeller and screwdriver slot on impeller to aid unjamming.- per the directions it is fussy about orientation when operating.- impeller is plastic.

Great value. Used to replace a failed hot water recirculating pump. Has been installed for a couple of months now and works perfectly with quiet operation.

Easy to install work as promised just added a 3/4 inch union for installation and a smart plug tu turn on/off (WiFi)
