I have low water pressure on my outside water valve when I'm trying to water my front lawn. The back is fine.

Question:I've tried to turn off the water at the front cut off valve which is down in my laundry room, let the presure build up and reopen to see if it will clear. But the prsure hasn't change. The back is fine.

Answers:
Sounds like the valve may be clogged. turn the water off at your meter then pull the stem out of the valve, turn the water back on at the meter and let it run for a few seconds, this should clear the problem.
