VEVOR Hot Water Recirculating Pump, 100W Water Circulation Pump With Timer, Auto Start/Close Ultra-silent Stainless Steel Head, for Electric Water Heater System/Facuet/Showerhead Circulation

Muy útil y cumple la expectativa

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.

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.

The threads on the pump are not normal 3/4" MPT so you need to use the unions then size back up to 3/4" if you need it. Other than that, I have never had a problem with this brand of products. Second note, the impeller plurge screw gasket is fragile. The screw slot is also shallow and easy to strip

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.

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.

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

After reading many of the reviews saying that the pipe ends were British Standard.Pipe in lieu of NPT, I decided to use the fittings the pump came with and solder 1/2" type L copper pipe into the fitting, it was a loose fit but not extreme. I had to tin the pipe first because of the loose fit. The flux would not pull solder into the joint by itself. After tinning the pipe and adding flux, was able to pull in solder. You see in the photo the installed pump. I have not started the pump yet. Need to complete the install at the sink. Just wanted everyone to know that if your somewhat of a DYI you have another option of install by soldering. I already had the extra pipe, tools and supplies to do the soldering. Just needed to purchase two copper bushings and a coupling for about $12 at the local big box home improvement store.Next weekend will be the bypass install and hopefully pump controls. I'll keep updating this with the finished.
