Question
I have 2 values that are leaking at the top knob valve, I also 1 valve that is leaking at the cap (where the rainjet information etc. is on) when the system is on.  What can I do to correct these problems, and where can I get parts?

Answer
Hey Larry, I believe home depot carries this brand. What I would do is buy a whole new valve, and either replace the whole valve, or you can take the screws off the top of the valve, and just replace the top. The cap that is leaking, actually has a plunger underneath the cap. Unscrew the cap, and take out the old plunger, and put the new plunger back in. When the system shut off, you will get a little water leaking from this cap, this is normal, but it should not leak when the valve is on. Good luck and have a great day.
