SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Changing the diaphragm on most valves will cure your symptoms. With some valves you're better off replacing the whole valve rather than repairing it.. What's the make and model of the valve?

Since the sprinklers work, no real problem as long as you have no leaks.

Just make sure no leaks. If you have a water meter make sure no water if flowing through it with all water in the house off.

I suppose, but I think there may be more to it than just flushing out the valve. I noticed that if I turn that zone on manually, all heads pop up immediately, and the sprinklers work fine...so, there's something else going on with that valve.

You can always remove valve guts and flush well.

No, this zone, like all of the others is flat...tks.

Is the zone downhill? You could lose the water in that zone at the lowest head and it then needs to fill up first before water comes out the heads.

Hello,

My home has 5 zones total: 3 in the front and 2 in the back. Recently, I've noticed that when zone 1, (which has appx 5 heads) comes on, it's taking about 60-90 seconds before all of heads pop up. The pressure is initially low but slowly builds to its normal flow (takes about another 30-45 seconds), and works normal for its alloted time. The remaining front zones come on and work fine. I'm wondering if there's a part in that valve that may be worn.

Any input is appreciated...tks.
