Question
Hi Guillermo,
I have an irrigation system on a well pump with a k-rain Hydrotek 4000 valve system feeding 4 zones. The system has been working in the past but recently I noticed that the sprinkler heads aren't spraying. Instead water is leaking from the heads of all 4 zones. I opened the valve and cleaned it out although there wasn't much dirt or debris that I could find and it is still having the same issue. Do you know what could be causing the problem and how to fix it? I bought the house last year but it was built in 2002 I believe with the irrigation system at the same time.
Thanks,
Albert.

Answer
Hi Albert
check the discharge valve make sure is full open. It's the one before the k4000.
the second problable is your pipes if are the iron ones it could be rusty inside, replace it with pvc if is posible. Other cause is the well level is low, you will need a well company to address this. Check the pump for proper voltage, also check for any leak at the main line.
