I have a six port Paramount pop up system and whenever I install my (new) module (gears are fine), the pressure rises ~10 psi and will not cycle through the zones. Seems to stick on one zone! All of the six heads rise and shoot water when module is removed. This is an older pool with 2 inch pipes and 2hp pump. Pressure is 22 psi without module, 33 when installed.
Thoughts??
