[C320-list] Repurposing head thru hull

I didn't repurpose the inlet but added a T to the sink drain.

My washdown hose goes to a spigot high up in the anchor 
well which has a cap on it when not in use, so I didn't use 
an antisiphon.

 In my case I keep the valve for the toilet feed closed and 
put a plug in the sink hole. No problems.  To flush the 
washdown pump and hose I can shut the seacock and fill 
the sink with fresh water then pump it through.
