Been a crappy week so forgive me if I seem fragmented. Traveled to a small rural farming community to locate a stuck valve yesterday, not many pics but...... I've worked for the landscaper a couple of times, first time for the home owner. Nicest guy in the world, the owner was, a bit of hard hearing and talked a lot but, a real gem of a human being. Here's one of the clocks, a proC with 2 zones was in the garage. I'm there to find zone 12 and hopefully 11 or 13 will be in the same box. I measure resistance on all zones, there's continuity and normal resistance 24-27 ohms. The water's off at this point but the zone is saturated. Owner says his landscaper has bragged my skills up and he's really anxious to watch me "do my thing". So I'm listening to the owners input and how he spent yesterday probing the lawn till his hands blistered, he hopes I have better luck. The owner asks about all the equipment I have stacked at the controller, pro800, pro900 and my pelican box of test equipment and how I trace the wire to track down the valve. I finally say I believe a successful locate is a combination of skill and luck and today I feel lucky and don't think I'm going to trace the wire path. I decide to use the pro900, I remove the correct common and zone 12 wire and close the loop, set it for direct connect, low frequency, solid tone. I walk to the area I have selected as my best bet, turn the receiver on, raise the gain to level 3 and get a hit where I'm standing. I then move a couple feet to my left where the tone increases, turn the gain down to 2 and move another foot, the tone increases. I turn the gain down to 1, lose tone altogether so I turn it to 2, zero in on the solenoid and stick my probe in the ground, thunk, there's the VB lid. The VB is full of roots and water, have the owner turn the water on and use my probe to listen to the water flowing through the valve. I was able to shut the zone down using the flow control. All this took about 15 minutes so the owner asks if I can troubleshoot the rest of the system, sure, at additional cost I can. All told I spent about 2 hours with a great guy, got everything identified and a ton of questions answered and was paid well to do it. Here's a nice aerial shot of the site Clock is in the lawn right off the pool and equipment, VB is left of the pool under the tree canopy.
