Catalina icebox problem

[Sailuke]

Hey i own a 1986 Catalina 27 standard rig with the traditional layout. right now my icebox drains right into the bilge, which is a big nono for me. I like my bilge when its not filled with food chunk's and orange juice. My sink drain sea cock is just inches away from the icebox drain, and i would be more comfortable having the water drain out through that instead of into my bilge. Now, i heard that if your heeled with a Catalina and the icebox is plumed directly to that through hull it fills the icebox with sea water, which is just a hazard. Should i put a check valve in, an anti siphon loop, or just leave it the way it is? It looks like a checkvalve would be the easiest option with the space available.

a check valve may work once.....but then you're going to have an icebox full of water again later.

an anti-siphon loop requires that you also have a pump to push the water over the top of the loop.

easiest solution is a pump with the discharge into the sink or cockpit, or some other above the heeled waterline discharge.

How about closing off the sink thru hull when sailing?
Or plumb the ice box drain to the shower sump?

Close the thru hull while sailing. A check valve will not work for long.

Mine drains to the bilge too, but I have refrigeration so I get very little drainage.

Shower sump likely drains to the bilge also, but one of the attwood/jabsco sump drain box/pump things would also solve your problem.
