Question
Hi Matt,
I am a fellow expert - I do Home Improvement, Water Quality and Travel - North Carolina and New Mexico.
Anyway, question on our Rainbird sprinkler system.  We have 2 sprinklers (in a run of 6) that are now running continuously.  Not much - just like a little leaking through.  At first I thought maybe it was just the last 2 in the run were draining because they were the low spot.  But now it has been 36+ hours and still leaking.  Any suggestions?
Thanks for your time.
Steve

Answer
Thanks for the question.
The problem your having is from a weeping valve. It probably has a tiny piece of debris in the valve which holds it open just a little.
You can try turning the valve on and off a number of time, sometime they clean themselves.
If not you'll need to dig-up the valve. Then remove the top flush the valve and look for any tiny debris on the valve.
Hope this helps.

Matt
