I am hoping you guys know more about sprinklers than I do.
I emailed Warren saying that the valve #4 (backyard) does not shutoff at the scheduled time. It even continues to stay on past the 15 minute kill time that I programmed into the Rain8II. Using my XTBM I've found that the StatusOff for Valve #4 is OFF so it is not the Rain8II.
When it stays on, I've had to shutoff the manual water supply valve. I am thinking this new cheap (~$15) valve has gone bad already as it fails to close. Recently I noticed there was some flooding in the backyard and found a leak in the pipes near a sprinkler head (I have yet to fix). Would the leak in the pipes cause a loss of back pressure which would prevent the valve #4 from closing?
EDIT: I figured it out. It seems these valves do need a certain amount of pressure to close. I fixed the leak..it was just a cracked riser luckily. I also adjusted the flow pressure at the valve and everything worked perfectly tonight. So I am going to assume it is fixed.
