Hello,
I just completed a full house remodel and all went (relatively) fine, but as always, little annoyances reveals themselves after all is done, when you live in the house.
One problem I have is the wait time for hot water in one bathroom. I ran 3/4" pex trunk lines the full lenght of the house to get adequate volume to all fixture. Fresh water comes from a well and then pass throught a water softener, so pressure is lower than a house feeded by city water, hence the choice to use 3/4" pex trunk lines. I have good volume now, but the farther bathroom takes forever to get hot water. This is easily explained as the cold water in the line must first flow to be replaced by hot water. The trunk line is around 70 feets from water heater to the end of line. I knew this when I opted for the 3/4" diameter, I just didnt expected the wait time to be so long.
My question is then should I replace the hot water trunk line for 1/2"? Will I see a drastic improvement or will it only be marginal? Is it ok to have 3/4" for cold and 1/2" for hot?
I know 70 feets is a long run so I'm also considering adding a second water heater near the remote bathroom... Is this a crazy idea?
Thank you for all advices !
