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...

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.

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. Update: Well, I did find a way to fix the threads and the pump itself has been installed for over 6 months with no problems. It does seem to be a fairly good quality machine. Pressure is good. No serious vibration or noise....

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.

I am a contractor so from my prospective it was easy to install. Overall I give it a 5 but individually quality is 3.5, price is a 10 and installing a 4, - also I bought 2 the other one is for my cnc plasma table fluid filtration system. I needed to get a 3/4” union for the pump to water heater but that’s normal with most pumps. For the low price of $35 the quality is great. It does have flaws its not perfect but if you are on a budget thes is i great pump and wow save you on waisted water and gas to heat it. I installed it on my water heater witch is the preferred installation. I used an inexpensive valve at the fertherest bathroom sink. But I recommend buying the stainless steal valve. Installation including the bypass valve tool 20 minutes I already had electric at the water heater. My only concern is it says it’s automatic on off but so far it on all the time. So I’m going to install a dusk to dawn Timmie and if it continues to run all day I’ll add ap pressure sensor switch or it may be the plastic bypass valve not shutting off if so an other reason to go with the better SS valve. But the pump is worth the $.

Perfecto

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

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.
