Forewarned being forearmed, I ordered the BSP (or G) to NPT 3/4" adapters, as I needed 3/4" feed out of the water heater, so I didn't want to use the 3/4" to 1/2" adapters that came with the pump. With the adapters, I had no leaks and no problems, certainly none of the problems that some have reported. I used minimal teflon tape (4 wraps or so), and the rubber gaskets that came with the fittings with no issues. The problem I did run into was the pump was more than I needed. It is rated at 120W at 30L/min, and I felt like the 15-9S was noisy. I could hear it through my garage wall, although my wife could not. With a circulation system that is fully insulated from the water heater through the house and back, all I needed was a trickle, so I decided the 15-6S with the stainless pump and multiple speeds was what I needed. I contacted the ZeroPone customer service and asked if there was a chance I could exchange the 15-9S for the smaller one I wanted, even though I was 4 months from the purchase date. (The extenuating circumstance was I was building a house and it was over 3 months before I could actually run the pump.) Not only did they agree to send me a 15-6S pump, they gave it to me with no return of the 15-9S necessary! It took me a while to get to installing the new pump, but it is whisper quiet and supplies more than enough hot water through the house, now at 40W instead of 120W. As another reviewer noted, there is no off switch, so I installed the pump on a smart plug and I have Alexa turn it on in the morning and off late at night. At 60 feet from the tank, it takes under 8 seconds to get hot water at my guest bathroom sink, and the shower is virtually instantly hot. I wish I could give it 4.5 stars and not 5 (Their customer service deserves 10!) only because the headline description clearly states NPT threads when it is not. Lower in the post of the pump, however, in the Q&A drop-down sections, it clearly states it is BSP threads, but you have to go looking for that information. I highly recommend this pump and this company, with the caveat of needing the correct adapters, also available on desertcart. The adapters can clearly be seen in my photos. The short video is only to give a sense of how quiet this pump is: I cannot hear it at all, although the water movement or my check valves cause a little noise. For the great comfort this little pump gives, at the purchase price and cost to run it, I'll put up with a tiny bit of noise! Review: Seems good. 6 months no issuesIf it makes it 2 years without issues I'll be satisfied. - Worked for me out of the box. It's surprisingly super quiet, was not expecting that. It's installed in the garage and I can barely hear it, if i cant hear it at all, standing next to it. Very very faint hum. Plugged it into a wifi smart outlet thing for control. Comes on between 6am and 10am, and 7pm and 11pm. Instant hot water in the whole house during that time. Seems pretty durable, no issues yet. Been about 6 months or so, on the same schedule. ## Features - 【Premium Material】- The recirculating pump uses heavy-duty stainless steel pump head, aluminum pump housing and PP impeller, featuring high resistance to stain, water, corrosion, leakage.
