Quieting the pump
Noisy pumps are the norm, except in the Space Shuttle, but that's just NASA.
Our 2013 Eagle 5er has a Shurflo and the owners manual for that pump says to not use rigid hose plumbing on either side. Well, ours was installedwith rigid pexright from the pump outlet side which transmitted the vibrations through the cabinets and walls. Today I cut that and put in a short loop of flexible hose and what a difference. So, if your pump seems noisy, check that out. Cheap fix.
