I only have experience with the Shurflo pump. Normal operation should be for the pump to activate anytime a faucet is opened. It should be immediate, and the pump should stay primed all the time--pressured up in the system.

As to my chasing down a problem--assuming you have Suites model, and the setup is similar to mine (mine is older, doesn't have the manifold setup)--I would utilize the winterizing suction line and see it picks up water in the winterizing line from a bucket. If if works fine from the bucket, then you probably have a leak in the suction side, or the check valve that isolates the pump when hooked up to shore water is bad.

I say the above thinking newer models are set up the same way as mine, but maybe in putting in the manifolds, this test would not work?
