Problem converting to drip
Hi,
First, I shoudl say I'm a DIYer, and have not really worked with a sprinkler or drip system much. I have done lots of fairly advanced DIY projects, so I do catch on quickly. Having said that, ffter several hours of trying to complete a simple conversion, I'm really frustrated! I have two Richdel valves that were part of an existing sprinkler system when I bought this house. Last summer, I had them working with the sprinklers. I live in phoenix, so I have removed all the grass (too much work), and am trying to convert everything to drip for desert landscaping. Last week, I cut the PVC and attached 1/2" poly tubing to both valves. Ran the tubing around the yard, tested with the auto controllers, and both lines started and stopped properly. Capped both lines, attached drippers and again tested. Both lines worked fine, except I had some blowouts.
I realized I needed to install pressure regulators, so today I went and bought two (25 psi), along with the necessary connectors. Installed a pressure regulator on both lines (after the valves), and after tightenting a few connections, valve 1 turned on and ran the drippers with no problems. Line 2 did not come on. No click or hum like I usually hear when the valve turns on. After fiddling with it for a while, I removed the solenoid, went to the store and bought a new one (811). Problem 1 is that although they look the same, the bottom of the existing solenoid looks different than the new one. The new one looks like this photo (the valves look like the Irritrol 2500 except mine don't seem to have the little shut-off lever right beneath the solenoid--I see from other posts that Irritrol bought out Richdel):

The existing part doesn't have the white part at the bottom (the plunger?), just a hole up inside where the threads are. I thought that maybe the plunger was stuck in the valve, but I tried to remove it with forceps, and it seems to be permanent. So . . . I can't replace the solenoid. I unscrewed the solenoid from Valve 1, and it looks the same (a hole, not a plunger).
So, I decided to put the old solenoids back in until I can work on it again. Now Valve 1 doesn't come on, either.
These valves worked fine last weekend. I do have waterproof wire nuts on all wires. I took them off and made sure everything is properly connected and tight.
I would also be interested in knowing how to bypass the valves and just run both lines manually until I can get the valves working properly.
Any help would be appreciated.
