One small problem with any self-righteous homeowner rant is that real-world experience cuts it off at the knees. Professional repairman eyes might immediately see the problem. Or not. A pro would also know how to fit in a master valve without any sturm und drang.It is not the controller. Had disconnected the wires from the solenoid and it still weeped. Also measured 0 volts out of zone three while weeping.
Sure I could have installed a quality automatic master valve and Installed a new controller to control it. Current controller is only 6 zone and all are used. It would also have required me to replumb the entire manifold in order to insert the new valve.
I was hoping for an experienced person to respond who might have encountered such an issue and had a suggestion for the correct fix.
The reason I have spent the time is that I am an engineer and always desire to know why something is failing rather than to simply mask the problem.
I do understand however people who do this for a living have to make a living and often times the quickest fix is the best.
After temporarily replumbing the zone #3 valve to its heads, and after running a complete sequence, the zone #3 head is once again weeping.
Here is a theory on why this is happening if anyone might care to offer a previous experience that might support the theory.
Theory: Zone #2 piping has somehow developed a slight and unintentional connection to the zone #3 piping downstream from the valves. And Zone #2 must be weeping but I did not see that because the lowest point in the system was zone #3.
I know that Zone#2 and Zone #3 pipes run parallel to each other for over 30 ft or so along side of the house. I know this from when I replaced a zone #2 head on the side of the house a few years back. When I dug up the head there were (3) 3/4" pvc pipes in close proximity to each other near that head. There was also a large tree root that had grown around the piping and that head.
Also to support this theory it seems that zone #2 and zone #3 must be run for a few minutes to establish the flow. Maybe possible that zone #2 must be full of water and zone #3 running creates a vacuum that begins the suck from zone #2 into #3.
I know this may sound like a stretch but it is my best guess at this point.
My next step is to focus on zone #2 diaphragm and valve assy. to see if it might be weeping.
Feel free to rip me for being an engineer or wanting to understand.
