Had a cracked PEB. The valve was weeping and I knew immediately it needed to be cut out but because of a very bad location the tech wanted to try a new diaphragm. I tried to convince him that if he didn't see anything obvious on the diaphragm it was a body crack and he should just accept the inevitable and replace it. Some lessons are best learned the hard way so after trying a new diaphragm which didn't solve the problem he ended up having to replace the valve anyway. Was able to show him a few tricks on replacing valves in really tight spots so all is well and a lesson learned. So this thread is a few tips on service issues. If PEB valves and what I call the HR-1 are weeping don't waste your time repairing it just cut it out. The Irritrol 205 is an irrigation superstar and should always be repaired. Hunter valves with SRV on the body should be cut out. For that matter any Hunter product with SR in its title should immediately be replaced. Keep at least one threaded valve in your truck in case you have to back one out due to lack of space or pipe. Keep a couple of 1" thrd by slip street ells for tight repairs. Learn to accept the inevitable in valve situations. Don' build kludges to get around problems. I recently undid a wiring kludge in which four valves had been wired together as two zones because the previous service guys couldn't find a faulty splice. Half my time was spent undoing their nightmare so I could find the original problem from ten years ago. Now the customer has 8 working zones instead of 6 and he was so pleased he rescheduled to have me totally renovate his system to my hearts content.
