I will work on it in the morning. I will start with the valves.
Before digging the yard up, should I install a pressure gauge and what pressure range should I be looking for?
Thanks for your help......
OK. No master valve. Pressure at 55 psi on down side of rpz with no other valves. It sounds like something stuck in line.
My thought for attempting to blow it out first would be removing and capping all heads for one zone, opening union on rpz and blowing air in last pipe on that line while that zone is activated.
Any other suggestions???
If that doesn't work, do I start digging?? Looking for anything that may be clogging the main line??
Thanks
