SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Pertinant issues:
1. Sprinklers leak (one area has all 3 sprinklers squirting water, not leaking...this area valve sounds like it isn't shutting completely off). In all other areas, most of the sprinklers leak after shut off.
2. Shutting off the controller (Toro TMC 212) does not stop the leak/flow; turning off the main on/off valve is the only way to stop the flow
3. Controller (computer) was replaced last year and worked well. This year I have had to reset the controller to default and start over several times. This has helped some scheduling problems.
4. Four (out of 5) of the areas have brand new irritrol valves (replaced this month) and most areas have brand new sprinkler heads.
5. This is California and our wells are marginally adequate. Much grit in the water and I have about 20' left in the well until having to lower the pump for the last time before drilling a new well
6. I am at 'wits end' trying to make this system function properly
