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 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.

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.

Not sure but, I think the threads at the top and bottom of this pump are a metric version of an English 'hose thread'. I bought an English ANSI hose coupling with a 3/4 NPT on its other side to replace the (Metric?) hose fitting that came with this disaster. It has what appears to be, a Metric internal hose thread on one side and an external metric 'straight' pipe thread on the other. I didn't trust it at all... Anyhow, after plumbing the recirculating pump to my hot water heater and before turning the water on, I felt pretty good about the integrity of my 'handy-work'. Well, that feeling quickly faded as soon as I flipped the water back on. It leaked horribly right at the pump bodies hose fittings. I may have tried again the following day if not for the uneasiness I received when reading the directions that came with the pump saying, 'Once a week I must slightly loosen the Pump Head Screw and release any air trapped in the pump body.' And oh-yeah, 'I must place a pan under the pump to collect the escaping water!' (Lol "Not Today..."). I had a Grundfos Comfort 10-16 recirculating pump hooked up that worked great. I live in SC and for the first time the temperature dropped down to 7 degs! My water pipes froze and that burned up my Grundfos pump. I originally paid $250.00 for the pump but found them to be over 400 bucs now! So, I tried to take the cheap way out with this Chinese made pump and just as I suspected, it was a miserable mistake... I guess I'm gonna bite the bullet $$$ and replace my burn-out pump with the German made pump I had.

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 $.

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.

Works as intended, exceeds expectations. Was easy for me to install. I bought it to circulate water in my chicken water system to help prevent frozen water when the temperature drops below freezing. I like the 2 different speed options. We recently had near zero temperatures and the pump kept working, no problems whatsoever. I would buy again if needed in other situations, great value for the money.

Put this on my hot tub and it goes out after 2 months
