With assistance by tech Josiah Schuett, yesterday….able to determine no power to both control valves responsible for back of 511 and 513. These valves are in the same vicinity as the ones responsible for the front area…that also had no power. I diagnosed those two earlier this week and installed battery powered solenoids/controllers accordingly. Today I did the same for the other 2 valves. Programmed and tested operation of valves…and all 4 are functioning properly. Also yesterday, Josiah replaced the broken sprinkler on the corner of 523….tested and adjusted. He then checked multiple dry areas around the various properties. He reported the valves and sprinklers were functioning properly….so I had him increase the percentage of run time across the board. What should be noted is the fact he was checking zones individually…any programming complications created by owner’s request and/or tinkering with start/run times could not be replicated. I will continue to monitor when possible. At this point, please write up tickets for individual problem areas…and I can get to those systematically, according to severity of issue (and within the framework of similar issues at multiple other properties). The tree root break in front of 509 is also repaired. That was a painstaking and piecemealed process, due to complications of working around roots…as well as obtaining specific parts to effectively reroute lines accordingly. Pressure tested repairs and filled hole(s). Since this root wreaking havoc was in the same general area as the control valves with no power, it is likely the wiring was also damaged by their relentless compression. – Mark
