I'm going to be putting in a system using the water out of the canal in the back yard. Should I be concerned about dirty water?? I've notice 98% of the neighbors, (fairly newer homes) have impacts instead of rotors to cover the open areas. What are your thoughts? I'd was thinking of using Rain Bird 5000 Series, or Hunter PGP rotors. What are your thaughts? Is there a wiring diagram out there for installing the timer,pump,and switch/relay pump system? Any help and thoughts are very welcome! Thank you!!!!!!!!
