VEVOR Hot Water Recirculating Pump, 93W 110V Water Circulator Pump, Automatic Start Circulating Pump NPT 3/4" w/Brass Fittings, Stainless Steel Head, 3 Speed Control for Electric Water Heater System

I bought this pump to keep water moving to my garage/Shop area as I used an insulated Boiler Hose to send cold water to my shop in the winter months.. I like having running water in my shop for all sorts of needs but I have many issues of freezing the insulated pipe so I needed to find a way to keep the water moving when not in use. I created a loop/Circle of the two 3.4" inch water lines and just recirculate the water until needed. I added a Tee to the line in my shop to attach a water/garden hose to and so far it has worked out quite well. I haven't gotten around to burying the insulated water hose which created this issue so this was my only hope until I can get around to doing it all the correct way! There never seems to be enough time in a day to get things done when the weather is nicer outside. I've already had a week of Sub Zero weather in northern MN during the night with no issue yet. Seems like a good pump. I have ran it on the highest speed of three to make sure the water keeps moving... Its gamble of course...

Perfecto

Product title has been revised since I bought it. Threads on the inlet and outlet are a 3/4-inch British Standard Pipe Parallel (BSPP) thread. Nice brass adaptors state 1/2 NPT, but they don't fit NPT or FIP threads. Previous product description and product instructions do not list a pipe thread type or size, nor is it stamped on the product. Nothing threaded in the US will fit this metric size. We never got it turned on as it leaks without pressure. Useless waste of money, and you pay return shipping to China. JUNK.

Works as described but a little loud

Good works quitely
