I have an 8 year old sprinkler system that never caused me any problems until a few months ago. It consists of 5 Hunter SPV valves and Raintree 6 zone. I recently replaced all solenoids, wiring, checked and cleaned the rubber diaphragms, and carefully placed them back in. All zones work except 3 and 5. It's perplexing to me. Can you help me out?
