They both sometimes leak from the valve when on (it’s not consistent), and it’s usually a steady stream of water.
On top of that, if I keep the water line flowing, but the valve should be shut, one continuously has a low flow across the entire system, and the other has a low flow for a few emitters.
For the first one, the valve is below where the rest of the line sits. And For the second one, the valve was installed higher than the drip system, so that could possibly the issue?
