Hi all,
I'm now to these forums so thanks for taking the time to read this. I'm totally stumped (and so was the plumber I called out) so I'm hoping you guys might be able to point me in another direction. Sorry for the long post, but This has been a multi-level issue. Here's what I've been dealing with:
I recently installed a brand new water heater (AO Smith) in my house. After I installed it, I found that I was barely able to get any hot water to any of the faucets in my house. Two-handle faucets where I could turn just the hot water on would run hot, but very low pressure. Anything with a mixing valve wouldn't get more than luke warm.
I first discovered that my PRV had gone bad. Pressure at the front hose bib (closest to the meter) was 100psi. I got a rebuild kit and installed that and brought the pressure down to 70psi.
I next discovered that the mixing valve in the master bath (closest taps to PRV) had a failed cartridge which was causing crossover. Shutting off the service stops to that valve solved the issue of not getting hot water to the rest of the house.
But now the water pressure in the entire house is extremely low - especially on the hot side. All of my hose bibs and the drain bib on the WH all show 70 PSI but the flow is super low inside. If I turn on two hot taps at once, both will just dribble.
I verified by watching the micrometer that there's no leak. I've confirmed that the WH lines are connected correctly and the water is heating up. I shut off the source of the crossover (for now).
What's my next move?
