The pump and the comfort valve were fairly easy for me to install (and I'm not all that good with plumbing). I removed the old hot water flex supply line on top of my hot water heater tank, connected the pump, and then reconnected a shorter flex supply line between the pump and the hot water pipe. Then I disconnected the supply lines under the sink in my master bath and connected the comfort valve. It took me a couple of hours, including a trip to the plumbing supply store. If you have any plumbing experience at all, it should take you less.
Initially I used the 24-hour timer that is built into the pump, but now Ihave it controlled by a separate 7-day timer, so that I can set it to different schedules depending on the day of the week (it comes on earlier on weekdays, and later on weekends and holidays).
The pump uses the cold water line as the return, so it makes the cold water lukewarm. This is the trade off for using this system. Also, as with any type of hot water recirculator system, you're trading water savings for energy. You'll waste less water while waiting for the water to run warm, but you are using more energy in the process, to keep the hot water pipe warm, and also to run the pump itself.
I first looked at recirculating pumps that would mount under the sink. But we had no 110V outlet under the sink for the pump. Some who had installed that kind of system said they could hear the pump even though it was very quiet. Since our house is extremely quiet I knew we would hear that type of pump. This Grundfos system suited our situation much better.
The Grundfos pump mounts on top of the water heater where we have a nearby 110V outlet. Any pump noise will be in the garage and out of earshot. The ingenious little Comfort Valve fits easily under the sink. No 110V required at the sink.
It only took about 10 minutes to install the pump on top of the water heater, not counting a trip to the hardware store. I had to buy an extension for the flexible pipe exiting the water heater. That 10 minutes to install also does not count time to bend the copper tubing. Copper is brittle so easy to break. I had to do it in small increments.
I plugged the pump in and set the timer. Done with that part.
For the under sink Comfort Valve Grundfos nicely included two 12" flexible pipes, however they did not have the proper fitting for my hot and cold water bibs. Another trip to the hardware store. It took me about 1/2 hour to install the Comfort Valve under the sink.
Once the Comfort Valve was installed, and I turned on the water under the sink, the system started working.Read more ›
