Hi everyone,
I'm fairly new to irrigation, but I'm learning a lot as I go about installing a drip system into my back yard. My question is this: is a check valve good enough to satisfy backflow prevention for a drip system, or do I need something else?
My water source will be tee'd off of the pipe that feeds a hose bib in the back yard, so the supply pipe will travel down a couple feet until it hits the ground, enters the valve box, and goes to the check valve, pressure regulator, screen filter, and manifold. The irrigation supply company I went to sold me a plastic check valve and said that would be sufficient, but I can't find anything online that even mentions this type of backflow preventor. They first brought out a heavy brass device, but then one of the guys there said that was overkill and a simple check valve would be fine for my small yard.
What do you think, is this suitable or do I need something more beefy? Also, I understand that a true vacuum breaker needs to be installed above the highest sprinkler, but since my water supply is even higher than that then will that cause a problem?
Thank you!
