VEVOR Hot Water Recirculating Pump, 10 GPM, Instant Circulation Circulator Pump System, 3-Speed Control, 0.13 HP, 110-120V, NPT 3/4 in to NPT 1/2 in Adapter, Stainless Steel Head, for Water Heaters

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.

Maybe it's a serviceable pump. I don't have any way of telling yet. It comes with, what appears to be 3/4" NPT input and output threads and includes 2 high quality brass 3/4 to 1/2 adapters. Unfortunately, on one side of the pump, the threads are cut so poorly into the casting that the coupler won't attach (and neither will anything else I've tried). It appears they were either cut out of round or simply not deep enough. Since I can't return it I'm going to try fixing the thread with a dremel. If that works, I'll review the pump itself and perhaps switch to 2 stars. As-is, it's not usable.

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.

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.

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.

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

I purchased the RS15-6SB variant Feb 26, 2023 and it's almost Dec 2024 now. This pump has worked satisfactorily for ~10 months & is still going strong. In my application it recirculates domestic hot water between oil boiler, wood boiler and solar systems tanks / exchangers. It sees DHW ranging in temperature from ~100°F to ~150°F at 30-50 PSI. I'm planning to purchase another, possibly the S15-9SR which can be set to switch on/off automatically. As seen in my three photos, my pump came with adaptor fittings to sweat 1/2" copper pipe. For the price and considering the other pumps available for this purpose, you can't expect more. To say the least I'm satisfied with this Vevor product. If it was rebranded, it could probably be sold for twice as much.
