I've replaced all the rubber parts on my sprinkler controller (see the diagram of similar unit), but it still continues to have a very slow drip (inside the line). There's no visible water on the outside of the controller, but if I remove the anti-siphon cap I can see a slow drip. The unit doesn't make any noise during the slow drip, so it doesn't sound like the pressure above the diaphragm is being released causing the seat washer to rise.
I suspected the seat might be damaged, but it feels smooth and I put another controller on it and it didn't leak.
I replaced diaphragms on other units and they worked, so I think I'm doing that correctly.
The brass unit looks in good condition. All the openings don't look corroded.
Any suggestions? Is there anything else I should be looking at to see if the brass unit is irreversibly damaged? My only other thought is that the stem that connects the seat washer to the diaphragm is worn and too much water is getting in around it into the bottom of the diaphragm.
Thanks!!!
