VEVORHot 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

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 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.

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.

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

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.

If you need a low powered pump that’s quiet this is a good choice. This is not a powerful pump, but works well. Don’t know about longevity yet. The auto on feature does a good job cutting pump on when water flows.There is confusion about the threads. These are straight threads meant to be used with a washer seal, unlike tapered npt threads that seal when the threads tighten.3/4 female iron pipe fittings FIP will screw on the pump with no problems. They seal with a rubber washer.

The first one of these I bought did not work and provided me with a shock. I then purchased another one, thinking that the first one not working was a fluke, I have purchased this brand of product before and had good luck with it.The second pump test out okay prior to installing in the water system. I could hear it running before installing it, but it did not run when installed. I removed the pump and tested it again and it was fine.I reinstalled it and it would not run when installed.This one is going back and I have ordered another brand.I believe these pumps are for boosting water pressure down the line. Not meant for circulation of water that is under pressure from the household system.If it would have run under pressure, I would have kept the second one in place.

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