Last year, I tested the pressure at my various rotors and found the pressure to be around 65-70 psi
To remedy this, I had a PRV installed set at 50 psi
This morning, I went out to test my rotors and was shocked to discover that they’re all at ~20 psi
I proceeded to double-check the pressure at the drain spigots in the basement and outside, confirming that they’re both around 50 psi
What could cause such a pressure loss between the supply and the rotors?
I don’t think that I have a leak as the loss is observable on multiple zones and I don’t seem to have a giant wet spot that I can see
