Sprinkler line won't shut off...

[bponline]

Greetings,

I posted this in the indoor plumbing section by mistake, thought I'd repost in the correct location.

I'm in the process of modifying my backyard sprinklers. I need to shut off the main water line to the house in order to remove a section of PVC in the main line coming out from under the house and connect a new piece from that main line to the valves. Shutting off the water to the house from the main valve is no problem, but for some reason the line to the backyard continues to run, but at a very slow rate. I thought that since it was the lowest line it might need a chance to drain, so I waited 20-30 minutes but it continues to run, again at a very low rate. Needless to say, this makes it diffficult to cement new PVC with a
good seal. Any ideas? Thanks.

Are you bleeding the line? If not, it may take longer than 30 minutes.

Hi Todd,

Sorry for the empty reply, I'm still getting used to the system.

Anyway, thanks for the advice. I'm not sure how to go about bleeding the line. Can you give me a description? Thanks!

"Bleeding the line" is what I think you are doing, but just in case: turn off the water main and then open a faucet at the lowest point and let it drain until there isn't anymore water running. It may take a while. My house is small so it doesn't take more than five minutes.

If that doesn't work, try lifting the pipe up enough to keep the water from running where you are working. I hope that helps and good luck
