Great pump and superior customer service

The media could not be loaded. I originally ordered the 15-9S pump, thinking I needed the volume for my water heater recirculation system. 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 Amazon. 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!

This product cost me a lot of money! NOT NPT

So I ordered this product based on the description. It was to replace an old one from a different brand. Well, my plumber came out and when it came time to put it in, it would not fit! This pump does not have three-quarter inch national pipe thread! It has three-quarter inch British standard pipe thread. National pipe thread is tapered, and BSP is a straight thread. Tapered threads are self-sealing and do not need or accommodate a washer. The fact that these come with sealing washers are a dead giveaway. BSP coincidentally is 18 thread per inch just like three-quarter inch NPT, but that’s the only commonality. Again, NPT is tapered and has a 60° thread cut angle with flat tops and valleys. BSP is 55° with rounded tops and valleys. Why does that matter? Because even if BSP was tapered, it would never seal! When I wrote the company about this, they told me I was wrong. When I insisted and found on THEIR website (buried deep in the manufacturers description) that it was in fact BSP, they didn’t even apologize to me. The expense of having a plumber come out twice is much more than the cost of this pump!It's even in the Q&A section, but hidden if you don't click on the question!

Hot water circulation pump

Much quitter than I thought I had to add a knight light to know if’s on, very pleased. Added a temperature controller 105 off to 95 on.

Patience is a virtue

I’ll be honest with you, if this had a normal NPT fitting this would be a much shorter review. However, given that this pump has a short BSP fitting it made getting a leak free fit very difficult. I ended up needing to purchase multiple additional fittings (BSP to NPT adapter, 3/4x3/4 female NPT & 3/4 NPT to push connect braided) to make it work. Make sure you are careful and use plenty of teflon tape and/or pipe dope. Ensure all rubber gaskets are not over tightened. And if you have enough patience, you can eventually make this work without a leak. Once I finally got a leak-free fit, the pump itself works great. I have the pump connected to a WiFi plug and set it to turn on for 5 min every half hour. It is very quiet and seems sturdy. Time will tell, but after I got through the process of getting a good fit it seems to be a good value.

Quiet and effective.

I needed an undersink hot water recirculation pump, not for instant hot water, but for freeze protection of some inaccessible water lines. The pump had to be "dumb" so an external temperature control switch could control it and circulate hot water back down the cold water line as needed. The pump is quiet, plenty powerful, and the price was right.The only two issues I ran into:1. One of the two units I ordered was missing the accessories, but a quick return solved that. (With proper return comments so it doesn't get shipped back out to someone else.....)2. I didn't realize there wasn't a backflow check valve in the pump. Adding an external one fixed that. Not the products fault.

Pump installation is challenging

First this is a well made pump. All metal in the actual pump housing. It should not fail if you read the instructions and take care of it.However, trying to find a way to mount if you are not using metal pipe is a real serious challenge. If you are thinking of using PEX or copper, it will not work. The pump housing lacks any form of a flange fitting to even create your own mounting. It is clearly is design only for use with cast iron pipe and that is getting to be very rare these days. Using PEX or copper will not provide enough mechanical (structural) support for the pump. In the long run, the vibrations from the pump may cause any solder joints to fail.Still looking for a great way to install it. I do like the pump but still, they could have casted a mounting flange in the pump housing!
