SeaAngel,
Is the ball valve located in the y-valve for directing the flow of waste
overboard or to your holding tank? If so, they can be serviced by taking off the front cover,
cleaning with vinegar and before re-assembly spraying with silicone spray on the valve and the mating surfaces. These valves need to be operated regularly otherwise they will no longer open.
In regards to your
Jabsco, go online and get an exploded diagram of your
head. Remove the
pump assembly from the bowl and disassemble. Check that all your internal
parts are not compromised and are functional. If there is a problem, you can get a
rebuild kit or buy individual
parts from their website. They are very simply assembled. THIS IS NOT ROCKET SCIENCE! When you reassemble your
pump, spray all the moving parts with silicone spray and treat the gaskets with a very light film of
marine grease. In thirty years of
boating on two different boats, I have only replaced one pump assembly housing(cracked) and have repaired my
current head (Raritan) several times in the last 17 years. If you ever intend to
cruise full-time, you need to know how to do this easy
maintenance. If you have any problems, take some pics and I'll be happy to walk you through any problems. You don't need to buy a book to fix your head. The diagrams and technical support offered by
Raritan and Jabasco are excellent. Good luck and safe sailing.
