:smt100 My vac-u-flush vacuum generator pump on my 1993 33 foot Sea Ray doesn't shut off. It seems to charge the vacuum tank and the bowl seals are good. It seems to hold the holded a vacuum and flushes normally. It's like the generator pump doesn't know when to cut off. It keeps running unless I shut down the battery. Some boaters at the marina said it could be a bad or clogged duck valve. What is a duck valve and where is it located in the system. Is it a difficult job to replace?
