Ok for anyone interested here is what I did...I traced the funny pipe from the sprinkler back to the 3/4" main line, only about 2ft. I removed the funny pipe and the 3/4 to 1/2 barbed coupler. I saw nothing clogging it but I flushed the line anyway. A lot of air came out before the water, I assume this is normal. I decided to replace the coupler, the funny pipe, the elbow, and the sprinkler (again). Turned on the zone and it is working beautifully. Maybe a rock came out and I just didn't see it,...
I have Hunter rotors. I capped 2 heads yesterday and saw no change in pressure, the head still didn't pop. I see no other option now except to dig up and back trace the line. Arrrgggghh
Thanks, I'll try capping a couple heads. The sprinkler is on the end, I just don't know if it is first or last. I've had no problems with the system during the 10 years I've had it. It just seemed odd that it would stop working. Btw, the heads I have on that zone are 3/4 in but I don't know the gpm rating, I assume I'll have to change to 1/2 in to reduce the flow rates.
I must say this has been a fantastic site for learning. I have read probably over a hundred posts and could probably install an irrigation system from scratch. I am however at wits end with a problem. I have 1 popup head on 1 zone that just doesn't have enough pressure to pop up. I replaced the head, pulled out the threaded connector from the funny pipe,flushed the line and still nothing. I checked the valve and opened it manually and ran it together with the system on. I really do not want to d...
