head

I bought this boat last year and the manual for the head (Port-a-Potti ) is missing. The owners manual refers to a seperate manual for this. I tried the searay website but no luck. The operation is almost self explanatory but I'd still like to have the manual. 2006 Sundeck 220

I have been fighting with an occasional bad smell from the head holding tank after flushing. I have determined through trial and error that the smell is venting from what I believe to be the vacuum release valve on the top of the tank. When the tanks are pumped out, this rubber flap allows air...

Just purchased a 1988 300 Weekender and 5 days into purchase vacuum flush system does not create vacuum, any ideas or thoughts are appreciated.:huh:
