One sprinkler leaking


I have sloppy front yard. I have installed new sprinklers two days back.. planning to lay down sod this weekend.

But one sprinkler which is at the lowest level is leaking. All the sprinklers 4 inch popups.

I think it is leaking because all the water is flowing to that side of the once the sprinkler valve is closed. The water is not have enough pressue to lift the pop up but has enough water to leak.. It is leaking from the top of the sprinkler.

How do I arrest this problem before I put down the sod ? Please help.

If it is only for a while after the system is off (few hours), than that would be "Low Head Drainage". It's normal, its just gravity at work. Pulls all the water out of the lines.

Now, if it does it 24/7. Then you have a bleeding valve solenoid that is not closing all the way. This would mean opening the valve and cleaning it. If that doesn't work, you have to replace it.

Until yesterday I see it only for few hours.. but today when I am back from work it is still leaking.. I put the water 24 hours ago..

Does that mean the problem is with the value not the sprinkler ? Is it right ?

You can try taking apart the zone valve and cleaning it. Otherwise, it need to be replaced. It is easy if you know what your doing.

You may want to call a sprinkler expert if it need to be replaced.
