Reverse blowing out fouled 1/4” drip lines
I have a drip system that came with the house. It’s on four zones. I was only using one of them for about four years and then I got the bug to plant more stuff in the other zones. Two work fine, short of a couple clogged or missing emitters that I replaced. One, though, seems to not work at all. The solenoid valve activates and I can hear and feel water running through it, but nothing comes out any of the emitters.
Question: I was thinking about taking the solenoid valve off and then blowing compressed air through each of the ends where the emitters attach. Is this a good idea, a bad idea, or just an idea?
Additional info. Two of the functioning zones have 3/4” pvc until it gets to manifolds and splits off to individual 1/4” lines. The other two zones I suspect snake around with 1/2 tubing with 1/4” coming off those. The one that isn’t working is mostly under pavers or 2” of gravel so I’m not excited about digging any more than necessary. If it were just dirt to dig, I’d probably just replace that zone with exactly what I want!
Thanks!
