Good question, BenT

There seems to be enough pressure in the system. I gave the test port
valve on the low side a tap and it gave me a short hiss. Didn't bother
to put a gauge on it because it didn't seem like a pressure sensor
issue at that point. The system was topped off in Sept., I think.
Maybe I should look into testing the pressure switches just the same.
Anyone know how to do a bypass test?
