I have a Polaris PB4-60Q Booster pump for my Polaris 380 and I am wondering what is causing this loud noise and if it is an easy repair or would it just be best to buy a new PB4-60 (Not the Q version) for around $225 shipped or so instead of attempting a repair on this one?

Is this a common problem with Polaris Booster pumps? Is there another brand recommended that may be better?
Also, how hard would it be to install a new pump?
