I recently had a irrigation system installed at my home. It was connected to my main line via T connection. I have a private well. Before I had this system installed I never had an issue, but now I have air in my water supply lines to my house after I run my irrigation system. The days I do not run my irrigation system I have no air in my lines. I have at least narrowed down to the air coming in from my irrigation system. My question is where they made the T connection to my main line and my irrigation booster pump that they installed they did not install any type of backflow preventer/check valve. This is why I'm suspecting the air is getting back into my main line. My main line is 3/4 PEX from my well to my house and it is 3/4 PEX from my T connection to my booster pump. I have 5 zones with 5 heads on each. They run 15min each zone with a 40 min delay inbetween each zone give the well sufficient time to rebuild. I've never had a problem with water levels dropping before as I have also watered previously with tripod sprinklers and ran them for 3 hrs straight with no breaks and never dropped water pressure so I have ruled out the water level dropping in my well. I just don't know what size/kind of backflow/check valve to put in that line? The line also has a turn off valve right after they t'ed into my main line so I will put it in directly after that. Any input would help. Thanks
