Sprinkler out put pressure up and down
I have a flo tech FP5172 1 1/2 horse irrigation pump. It is hooked up to a well. The problem I am having is the sprinkler output/ pressure goes up and down every three to five seconds. It sounds as if air is pushing out and no longer maintains the initial high, sustained output it did when it was first installed 3 months ago.

You say it sounds like air? air passing through a pump that also has a flow of water typically souds like bb's are passing trough the pump...if this is what you are hearing you may have a bad/cracked suction line or collapsed/dried up well..no way to know for sure without actually being there. otherwise adjust pressure switch to a higher shut off. or look for a bad valve. if a valve is not opening all the way it restricts flow hence it uses less water creating a cycling effect.best if you can hook a pressure gauge to the faucet to check pressure.
