Built a new house and moved in April last year. Since we moved in, when we turn on the cold water only anywhere in the house, we get warm to very hot water for anywhere from 20 seconds to 3 or 4 minutes, depending on where we are in the house and time of day. The house is 6,000 sf and one level, with 20+ cold water drops. This happens on the other side of this wall, all the way to the other side of the house, including the outside hose bibs and refrigerator water lines.
The builder and plumbers have been out multiple times and can't seem to fix it. They haven't been out in a while, saying they are trying to figure it out but I don't have much hope. If the recirc pump is off, this doesn't happen. However, when it's off, our master bathroom and shower, which is furthest from the heaters, never really get hot and take a while to even get warm.
We are on well water with 2 hot water heaters and a recirculation pump (F in photo). The line from the well filtration units runs ~125' to the hot water heaters (C). The heaters are in the SW corner of the house in the garage. Hot water runs from there to the far end of the house through probably a good 150' of pex. At the end of the hot water line run, a dedicated recirculation line takes it back to the heaters (B). (A) in the photo goes to a hose bib, which is turned off right now.
The plumbers have tried adding check valves, (D) and (E), but it didn't solve the problem.
Any ideas? I don't know what else to try and the professionals haven't been any help over the last 9 months.
Thanks.
