Hey, like I said, I read the first post, no mention of water running or valve type. I went with what I have encountered the most often in the last 40 years of servicing filtration. Troubleshooting is a process of procedural deduction and most competent technicians always start with the obvious or most common and work backwards from there. So I didn't hit he nail on the head the first time given the information I had to go on. Had I been following the thread, which I wasn't, after the OP said it ticks all the time I would have then moved on to the mechanical timer. Note that my detractor never nailed the problem either and only bothered to throw his two cents worth of useless comments in in an attempt to illicit a negative response from me in the way of a personal insult. Hey, not gonna happen. No point. We all know who he is and what he is all about by now.
Fortunately most of the professionals like Akspdvan and others that post here are just that and willing to help rather than waste everyone's time trying to start an argument, or tossing insults. I guess at least one member here must br anti DIY LOL.
