I recently purchased a house and I am unable get the sprinkler in working order. This unit has Richdel Controller and Amtek valves. It also has a well pump. I found the main breaker was defective as well as the relay calling for the pump to kick on. I bypassed the relay and changed out the breaker. Now the pump starts and one zone begins to spray. Unfortionately the zone is the only one that comes on regardless which zone in on in the control panel. It is the zone closet to the well pump. I have to shut down the well pump for value to stop.
There ARE times when it's okay to call in a professional. You could have something very, very simple to deal with. Or not. Some pump setups have the unfortunate ability to do themselves damage, if everything isn't just right.
