Another water pump question...

2020 320-s Boondock, total of 22 nights of use last summer. Dewinterized a month ago. Water pump works, but it is MUCH louder than last year. Sounds like it is jack hammering in wall in sower area. Any ideas why> water in tank is full.

Some owners have put pipe insulation over the pipes leading into the pump.  Some threads here: https://www.google.com/search?q=loud+pump++site:tab-rv.vanillacommunity.com&client=firefox-b-1-d&sxsrf=ALeKk03lXD2oXQsOPk9Qwt0MHU80jKlPow:1621277551139&ei=b7uiYNv5B8yv0PEPmpOt-AI&oq=loud+pump++site:tab-rv.vanillacommunity.com&gs_lcp=Cgdnd3Mtd2l6EAM6BwgAEEcQsANQjBVYijRgpTpoAnACeACAAZMCiAHqFZIBBjE3LjMuNJgBAKABAaoBB2d3cy13aXrIAQTAAQE&sclient=gws-wiz&ved=0ahUKEwib7ZHEsdHwAhXMFzQIHZpJCy8Q4dUDCA0&uact=5

I adjusted the pressure bypass and shut off switch on the bottom of the Pentar pump.  Works quietly now.  I did however leave a square bit and the square bit extender somwhere out or arms reach in the bottom of the access area. Oy.
