Oh boy. I would find someone experienced in the marina next to you and ask them to go over your boats systems with you.
3. How do I tell if all my seacocks are working?close them and open
raw water strainer...clean strainer. Then crack open seacock for a second, water should quickly flood strainer, close seacock ,water should stop, if not hurredly close strainer and schedule seacock replacement next haulout.
2.Is the
holding tank vent filter possibly causing the bulging waste tank? Yes. Have pump out guy backflush vents during next pumpout, mine uses something that looks like a
toilet plunger hooked to a garden hose, open a
head flush valve during this procedure to prevent over pressuring holding tank. If a flush valve is leaking in one of the heads this could cause both symtoms you are experiencing.
1. You got a leak or bad valve somewhere, are you hooked up to shore water? If so disconnect it, I never use my shore water connection, even when
living aboard. If it
leaks it will sink your
boat. Fill up the
fresh water tank every few days instead. It will keep the water fresh in the tank.
Then start at the tank, follow lines to pump, the fresh water tank should never be under pressure, if it is, (shore water hooked up?, bad pump?). Check pump pressure and shutoff switch, check entire system for
leaks up to each fawcet. Good Luck
Welcome to boat
ownership.
You might get a small amount of expension in the tanks if the vents are clogged as
winter turns to summer, Around here they are a favorite spot for wasp nests, the holding tank vent will clog with dried
toilet paper. PS I'm not kidding about shore water.
