Low pressure on 1 zone

Wet Boots for the win. Thanks to everyone who helped me troubleshoot this. I should have tried to replace or look at the house pressure regulator earlier. It would give a consistant pressure across when activating zones, but when I would test other days then it would be a different pressure without me adjusting the pressure regulator. $85 for a new regulator, some elbow grease, and a few minutes and everything works great. I had heard my neighborhood has bad/fluctuating water pressure and believ...

Low pressure on 1 zone

Lars, that is actually what I going to investigate now. I am waiting on the city to come out and check the check valve on the system. I have asked around, and apparently they are going bad around town at a more than normal rate. Mrfixit, they are 3 rainbird model 3500 sprinklers in the zone. I have 3 of those same sprinklers on 2 other zones on my system that work flawlessly. I have changed the type and number of sprinklers in the zone with the same results and the same "fix". Wet Boots, I have ...

Low pressure on 1 zone

Well, I replaced the valve. Same result. I have to pop a valve or bleed valve on another zone for a second and close it while the low pressure zone is on. This is the only thing that makes the low pressure zone have full pressure. In my mind, I have no other options. I re-plumbed the entire zone and have tried 3 different valves. This is just crazy to me. I guess I will just go insane and the grass will not get watered unless I do the workaround whenever I want to water.

Low pressure on 1 zone

So you are saying that the valve you listed is just a superior valve? I would be willing to pay $100 for a guaranteed no headache fix. I will try the pressure test with a gauge I guess. It is just a really weird problem. I do get full pressure on the zone, but only after opening the normal valve or bleed valve of another zone for a second and closing it. I know I have said this already, but the zone is capable of getting full pressure this way.

Low pressure on 1 zone

Anyone else have some kind of idea? I am thinking about replacing the valve yet again. Maybe I have installed 2 bad valves...I don't know at this point. It is driving me a little insane.

Low pressure on 1 zone

Just 3 rainbird sprinklers on the zone. I have other zones that have 3 and work fine with no "workaround". Like I said, it is really weird, they do get full pressure but only after popping another zone's valve or bleed open for about 1 second and then close it. Immediately after doing that the pressure on the low pressure zone increases to where it should be. No leaking from the sprinkler heads. I don't think it is a nozzle problem since I am able to get full pressure with the workaround.

Low pressure on 1 zone

I have seen a large amount written on this subject, but I cannot find one that fits my situation. I have a 9 zone system with Hunter PGV-ASV valves. I installed all 9 valves new on my system since a few of the old valves had issues. My zone 5 never really acted right even after changing the valve. I ended up installing all new PVC to the sprinkler heads hoping this would fix the low pressure problem. It basically had no pressure before I re-plumbed due to some leaks in the pipes. I am getting mo...
