This is a general question. I have two heads. The waste lines go to a Y valve which directs the waste either overboard
or to a holding tank
. The holding tank
has an access point topside for pump outs or a seacock down below to dump overboard
. My question is - Why? It seems that if the holding tank dumps to the sea then the waste line should go directly to the tank from the toilet. This would eliminate 4 connection points (potential leaks) and about 10' extra of waste hose (which would contain waste products).
I would propose to go directly to the tank from the toilet. What problem will I have? Am I missing something?
Also, the seacock from the bottom of the tank is close to the thru hull
. This means that there is always waste in the hose. Why not have the seacock at the bottom of the tank?
Feedback is greatly appreciated.
