I am replacing an irrigation system on a hillside with a gradual slope. Do I need to install sprayers with internal check valves? I heard that the internal check valves eliminate "water hammer" damage on the sprayers. What happens in winter? Will water trapped in the pipes cause more pipe ruptures? Thanks.
I am currently replacing my irrigation system. The previous contractor used cheap products and did not install them properly. I am thinking about using a Hunter Pro-C or Rainbird ESP-LX controller. I need to install a backflow preventer. Which companies make the best valves and sprayers? My yard is on a hillside. Does anyone have any experience with rainbird 1800-SAM and 1800-PRS-SAM sprayers? I would appreciate anyones opinions. Thanks in advance.
