Have you plumbers run into situations of erratic valve behavior when a
one of more pressure balance anti-scald valves are in the loop and the
circulating pump is running?
I have heard that the valves don't like the differential in pressure
between hot and cold lines.
Thanks in advance.
Isn't the idea of a pressure balanceing valve based on diff pressure in
I have heard of situations in large buildings where the pressure difference
was soo great
that the sinks stopped working. I dont remember if it was the hot or cold
had the higher pressure but that was all that came out of the spout unless
you had the
knob wayyyy to one side and there was only a hair of any adjustment left.
scald feature is to protect agianst a sudden drop in cold pressure.
What do you mean by erratic valve behavior.
Are you sure it is related to the recirc?
