I've got an in-floor cleaning system that has about fourteen,um, valves or nozzle heads that rotate around (which is to say about three or four are active for a while and then they close and the next group starts).

Today I noticed that four only are working -- the rest don't cycle. I have the Jandy control pad inside but all it says is the in-floor system is "enabled" (you can enable or disable it). Any ideas or is it time to call in the pros?
