Question
I have a couple of heads that leak water out of the head. They leak thought the day and cause a puddle by the heads that are leaking. Please help with this.
Thanks Brendon

Answer
If you are on a slope, and the water is leaking out of the lowest heads, you have low head drainage.  This can be solved by installing sprinklers that have a check valve in them.  If it is not low head, then you probably have a leaky control valve.  Turn off the water and dissemble the valve, and clean all the internal parts carefully.  Rememver to clean under the solenoid.  Check the rubber diaphragm for holes or tears and replace if damaged.  Reassemble and try it out.
