I do plumbing in Austin Tx and i like to use the Navien NPE-240A2, it has the built-in in recirculation pump and we run the the water loop as close to the anglestop, shower valve etc as possible and return it back to the return inlet. When customers open the faucet, it take like 2 seconds for the how water to come out (even in a kitchen island). We also use the shortest possible flex on the hot side to reduce even more the wait. We also insulate every single hot water line with 1" thick insulation to prevent heat loss.

So what do you think about recirculating pumps? I was thinking that running continuous hot chlorinated water through PEX for 30+ years sounds like a recipe for disaster, but your thoughts? (Dedicated return line to the fixture furthest away)

I have look at many of your video and they are very educational.. I have an issue that you might not have covered. When I purchased this home, it has two rheem water heater in parallel. I assumed both were working as we are getting hot water in the home. I was doing the maintenance using vinegar to remove any calcium build up. One of the units flushed perfectly well, so moved to the second unit. Hooked up both hoses and turned on the pump.. nothing out of the hot. We checked the filter on the inlet (cold) side but it was clean. After many days of research, I saw an article to use Lime Away 28oz to 2 gallons of water and set the pump again... No water out the hot line.. We allowed it to soak and repeat the process every 30 mins for about 4 hour.. Still nothing through the hot line. I know this is clogged but how to I fix this.. Is there something that we can take out and clean etc. Any assistance or guidance will be appreciated.

Hello I've had a ticklish hot water tank for 15 years recently in 2018 good results then bring a pump I saw it on This Old House where they where they said to put end of the father's fixture on your hot it water side it works quite well it takes the cold water from the hot side pumps it to the cold side and when it reaches temperature turns off and the check valve closes it could be either push button on demand or on a timer something to look into and talk about have a great one
