My lakeside pump handles two neighbors and my sprinkler system. Upon starting this year's season I noticed that all three systems are very erratic. I'll call them A, B, and C: When A is on one or more stations in B are on. I didn'g check C. when B is on at least one more station is on. When C is on some stations nearly fail to come on; I didn't check but the implication is that water was going elswhere. What could be the problem here? Could marginal pump pressure affect solenoid operation? Shoul...
