VEVOR Hot Water Recirculating Pump, 93W, 110V Water Circulator Pump, Circulation Pump, 3/4″ G Thread to 1/2″ NPT Brass Adapter, 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...

I added radiators to extension room and hot water flow was weak and room cold. I connected this recirculating pump and it works fantastic. I had concerns with possible leaks since I used shark bites to connect most of the copper pipes, no leaks after a month. My oil furnace also heats my household water, so the recirculator turns on when that occurs. I was told to simply wire the recirculator to the circulator motor wire. I plan to just turn off in the spring once heat is no longer needed in the extension room. Having it run more actually keeps the hot water moving and saves on heating oil as it continues to keep the water flowing until it is completely cooled. The motor heats up to 135 degrees, which seemed concerning, but drops back down to the 80's after the furnace shuts off so it is just the hot water running through it that causes the heat not some motor issue. It has just 2 prongs; so easy to plug into a cheap timer if I only want to heat the extension room during my work hours. I will wait to see what my electric bill looks like before doing so. It did give off a light burning smell at first, that subsided in a few hours; likely the excess plumbing material from the solder job on the 2 parts that shark bites did not have a size for (I guess a European 3/4" fitting is slightly smaller). I will buy another to have for future use since the price is amazing. My Heating company came out for the annual furnace inspection/ cleaning and looked at my project, gave the thumbs up and said that he would have billed me $700 for the same thing.

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.

This arrived with broken plastic on the electronics cover. While I was waiting to return it, I found a cheaper pump and ordered it to replace this one. I have had other Vevor products and have been impressed with them as a good value, and I have no reason to assume this one would be any different. -1 star for inadequate shipping protection.

I’ve been running one of these for over a year now without issue. I love having hot water almost instantly at the tap. It’s worth the energy consumption to waste less water (and time) waiting for hot water to arrive at the tap. It was a lot of work running an extra hot water return line, but so worth it.

Very good product, met my expectations

got one year out of it running through a water coil in a stoker for circulation. the wiring could be better

This pump was a direct replacement to a hot tub circulation pump that cost between $175 to $250 to replace. It needed basic pvc and brass pieces to complete and it slid right into my tub perfectly. I run it on the lowest speed. Speed 3 is pretty decent output, but for a 4 man tub, speed one is sufficient. Still better output for heater and ozinator bubbler than the old one. $31.00 vs. $200 and up? No contest. Great components and runs absolutely silent. I had to add a ground wire terminal to the body by using existing screw on motor body cover, but it is double bonded, and double grounded.

Funciona correctamente. Tal como se pública. No hace ruido. Buena compra.

Muy buena porque sirve para lo q se requiere, solo q llego una de las tuercas defectuosas

Muy útil con el regulador de tiempo

Seems to work ok but the bypass valve gets noisy every now and then for a couple of minutes then stops. Annoying.

Works but you need to prime it. Once you fill up the intake and out with water and blow out the air, it will start and work like a charm. But it needs priming!
