    That's a no brainer. The pump kicks on every 4 minutes because you're losing pressure through the check valve and the noise you hear is the water escaping.
    This could be as simple as a piece of trash preventing the valve from closing or it could be a fault check valve.
    Either way you have to shut the system down, pull the check valve and check. Good luck, Tom
