Hello everyone, this is my first post as I am a new member! My parents just purchased a 1997 47' Sabreline which has been amazing this summer so far. We went on a day trip yesterday and came across some troubles with the vacuflush system in the forward head. For some reason the pump stopped working while someone was using it. Has anyone heard of a problem like this before? Do the pumps stop working altogether if there is a blockage in the pipes? any help regarding this would be great!
