Near instant got water

Added this to my new hot water heater and wow what a difference. Hot water within seconds. No more waiting for hot water. It was very easy to install on a new hot water heater. I could see a little difficulty with an existing water heater but not to bad. Very good price too.

Works somewhat

I purchased this system in an effort to have instant hot water at the kitchen sink without the use of an existing five gallon electric hot water tank. I wanted to eliminate the worry of a tank leaking on the hardwood floor. The system will keep hot water at the first two sinks inside the house. I'm very pleased by the results for those two sinks. However, the main purpose for the purchase was to eliminate the electric tank under the kitchen sink and it doesn't look as if that is going to happen. I've had the system for three weeks and even changed out the thermostatic controlled valve under the sink and still don't have hot water at the kitchen sink. I still have to wait for the hot water to reach the kitchen sink. Therefore, when the dishwasher is used I have to stand at the kitchen sink and run the hot water until it warms up enough for the dishes to be cleaned. It seem to me if Grundfos simply provided an adjustable thermostatically controlled valve the customer could dial in the temperature they wanted at the last sink therefore creating a perfect system. I hope Grundfos reads this and fixed the problem. If I only had hot water at the kitchen sink I would be a happy camper.

Hot water at the sink within 5 seconds!

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.

Great product and SUPPLIER.

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.

This is my second purchase of this Grundfos Pump

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.

Great product, tried and tested.

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.

Trusted brand, works well

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. 🤔

Amazing. Where has this been all my life?

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).

Hi George, thanks for writing in. Yes, this can be used with a tankless water heater if you have a recirculation line plumbed into your system.

Yes, the Comfort Hot Water Recirculation pump may be used with multiple thermal by-pass valves. This set-up would be required when the home has a branched hot water line.

You should confirm with the manufacturer of your tankless heater, as some manufacturers void or cut your warranty in half is used w a recirculator pump.

Q: I have a 6 unit apt bldg., which has a basement (where my hot water tank is located), a first floor (not using this hot water tank), and a second and third floor. Will this pump be able to circulate hot water up 3 floors, and across the building (roughly 50 feet)? If not, do you have any suggestions? Thanks!

Asked by Andy 10 years ago

The pump should be able to handle such a distance, as explained in the installation manual "For the greatest effect, the valve should be located at a faucet with the greatest piping distance from the hot water heater." If your home has a branched hot water line, more than one valve may be necessary

Q: My Home is two stories, with the upstairs bathroom as far away from the water heater (located in the garage), as the kitchen sink. Is it necessary for two comfort valves to be installed and if so, will this pump work properly under that condition. Thanks

Q: My hot water system is already equipped with recirculation lines. My existing pump is plumbed in at the bottom of the tank. Can I use this one and just not use the included valve? Leaving my existing, non-functioning pump installed?

If there is a recirculation line installed, the UP15-10SU7P/TLC and Comfort Valve are not the best choice. This system is designed for homes that do not have a dedicated return line. The best course of action would be to replace the non-functioning pump.

Q: Can this unit be used in a system with a ground well? I'm concerned the pressurized tank would not allow the mixing valve to push hot water line thru the cold line. I would think the recirculating pump would be "fighting" the well pump.

Q: I need the answer from the manual page 5 and 6 but I don't have adobe reader on my computer. Can someone tell me how the pins are to be set for the timer? Are pins up for hot water or pushed in for hot water? CUSTOMER CARE A: It is on page 5 and 6 of the manual linked below: http://s3.supplyhouse.com/manuals/1294349331588/43377_PROD_FILE.pdf

The manual states: 1. Set the timer switch to the actual time by turning the programming ring in the direction of the arrow until the timing arrow points to the actual time on the ring. 2. Plug in the power cord from the circulator and set the manual switch to the "ON" position. The circulator will now start. 3. Set the required "ON"/"OFF" times on the programming ring by pushing the programming tabs either away from or toward the center of the ring. Tabs pushed away from the center indicate the circulator is switched "ON" while tabs pushed toward the center indicate the circulator is switched "OFF". 4. Set the manual switch to the "TIMER"position. The circulator will now start/ stop according to the settings of the programming tabs.
