I just installed the Wireless Flow Meter and it does detect water flow and zones open, etc. HOWEVER, it is not enough pressure to “pop” the heads. Instead, they bubble.
Setup: Main line 1" PVC to 3/4" Wireless Flow Meter to 1" Main line, where it continues.
Zones show (after calibration) around 1.9 GPM.
I have it set to allow for 1 min of “pressure time”, which really only needs 15 seconds.
HELP!
