UP15-10SU7P TLC, Comfort Hot Water Recirculation Pump, 3/4" NPT, 115 V

Stopped by the water heater section of my local hardware store. Picked up: 3/4-inch Dielectric Heat Trap Nipple, SharkBite 18-in 3/4 -in Push-to-connect Inlet x 3/4 -in FIP Outlet Braided stainless steel Water heater connector, yellow plumbers tape, pipe dope, cost less than $50, took 30 minutes to install at the water heater, took another 30 minutes to install valve under the kitchen sink. Used an extension cord for power source. Wish I would have done this as soon as we moved in 14 years ago.

I used this pump in a dedicated hot water loop, with an isolatin valve and fill/drain valve on the supply side and also diaelectric unions on both sides of the pump for easy repair. The discharge side after the union has an isolation valve then a spring loaded check valve just before the actual connection to the cold water line feeding my indirect hot water tank. This pump performed exactly as I expected it to, I now have hot water instantly at all sinks in the loop. I have fine tuned the run times on the pump using the built in clock on the pump. Would recommend this pump and Supply House to anyone who wants to save water. It was delivered to my house in 2 days. Thank you Supply House.

Easy install, I recommend these to all my clients with long hot water delivery times

Hot water is available within seconds now.

This pump works great, is super easy to install and lasts a long time. My first one lasted over ten years. Having hard water here in the Phoenix area finally bogged down the impeller. I actually took it apart and cleaned it up and it ran just fine but I decided on a new one anyway.

I'm very happy with the pump. The price was great, and the shipping was very fast - next day delivery.

Easy install

It replaced another Grundfos pump which had reached the end of its useful life. Love having virtually instant hot water, could never go back to the way it was before.

Product is great. Only disappointment is that I had already ran a dedicated return line and called Supply House to get exactly what I needed. They recommended this one, although I really didn't need the under sink cold water return parts. I would think I paid quite a bit extra for an unnecissary part. Thought calling ahead to explain and ask for best part might have saved me from wasting money. 🤔

Furthest sink (now using the bridge valve) used to wait about 2 minutes for warm water; that went down to 1-2 *seconds* (no exaggeration). Pump is *very* quiet. Mine is on the same circuit as my garage door opener, with no overload problems. The idea here is to create a continuous draw of hot water, but that's sent back via cold lines instead of lost down the drain (via a valve bridging the two). Note that it provides quick access to *warm* water, not instant hot. That's almost always want you want anyway -- not cold, and not scalding hot. The cold line is warmed a little as well, but I never require actual cold water. Another benefit to this is that both hot & cold pipes are very unlikely to freeze -- they always have at least warm water through them. Components are simple, and installation was very easy. Inlet is std 3/4" FIP swivel, and outlet is std 3/4" MIP. The remote hot-cold bridge valve needed adapters in my case, and they were included. The control timer is mechanical, so not "smart", but then no worries about electrical spikes / surges / brown-outs damaging it. Timer is like a security timer -- manual on, manual off, auto. Don't need to run the pump to use the water heater; when it's off, water still goes through like it's not even there. Pump uses 110v, and has a 10 ft cord. No special installation; just plug it into a std outlet. A lot cheaper than an under-sink tankless system I'd been considering, and the whole house benefits (esp in winter).
