Thanks! That did the trick. I appreciate the help. I did not know that the cap came off. I thought they were sealed. Now that the water is no longer leaking out the backflow vent, I have developed a new problem though. Unless I manually turn the flow valve completely off, the pressure keeps water flowing through the valve and out the drip lines. Again, I have replaced the solenoid and the valve diaphragm, so why is the valve allowing water to flow through? Is it time to replace the whole thing?
Just discovered this site and thought I would ask about my problem. I have a 4 zone sprinkler and drip system, with a Rainbird Rainjet RJ713 Classic 1" valve for zone 4. The zone has drip and some misters. Anyway, I turned the zone off last year as our dogs ate most of the drip lines and the larger tubing had some holes. I finally fixed it all this spring, and admittedly reduced the number of drip lines for the zone but not by that many. I also replaced the diaphram in the valve for good measure...
