My C&C 30 is currently set up with a bladder for grey water. Galley sink, and Head sink drains are pumped into the cockpit lazarette into a bladder. I would like to change the system BACK to it's original configuration MINUS head pumpout directly overboard. I do have a blackwater tank, but can do without the grey water bladder. In the great lakes, so no option for discharge of head overboard is preferred.
On inspection I found:
1) abandoned vent hose, 5/8" in diameter which is at the rub-rail in the head area. I believe the holding tank has another vent aft already.
2) empty pad, I PRESUME was where original Y-Valve was located
3) abandoned 2" thru-hull. Looks to be original toilet discharge.
4) IN-USE 1" thru-hull for toilet intake.
5) abandoned thru-hull which looks to be where sink (?and shower sump?) discharged
The pickup in the shower pan goes to a poorly installed ball valve (not original) thru a strainer, then to an electric pump mounted on forward bulkhead of the head compartment, which then runs through several adaptors and finally a T, and then to the pump for the bladder in the cockpit lazarette. Sink drains from basin into the T mentioned above, then to the bladder pump. I have used the sin, not the shower thus far.
I am confused as to original use of the vent, I am thinking it was the anti-siphon for direct discharge of the toilet???
How does the shower sump/pump drain overboard? Does it tie into the sink drain? Is there an anti-siphon for that somewhere?
Of course I will be pulling out Peggie's book, but inital glance into the current plumbing has me confused.
Thanks
