Question
how do i remove the cover from a hydrotek 4000, 4 zone irrigation valve.  iv'e removed the screws and tried to pry the cover up, but don't want to pry too hard for fear of breaking the cover.  any suggestions?

Answer
Bob,
Thanks for the question.
That is one of the few items in the irrigation biz I have not worked on. So, I hate to give you bad information. I've attached a web link to the a website with a break down of the parts. I hope it will be useful. Sorry, I can't be more helpful.
