Question
I installed a small system in my yard. 4 valves and a lot of sprinklers. The water pressure is 35 psi but I have really poor coverage. Do you have any suggestions? Thanks

Answer
Hi Joe, I would love to help you out with your problem, but P'm going to need a little more info. If you could answer these questions I will get back to you with some options to fix everything.
1.How big of an area are you watering?
2.What are the valve watering?
3.Are their any slope or valleys?
4. What type and brand of valve and heads are you using?
5.Is there a pressure regulator and back flow device in place?
Let me know and we'll straighten it all out
