I discovered that some sort of hose had been passed through the bulkhead between the galley and the engine compartment, port side outboard of forward holding tank. The hose had been removed but the silicone used to seal the bulkhead penetration was still there. Any idea what the hose would have been? A/C condensate pan drain? I'd like to find out before I re-install the holding tank. Thanks.

What diameter is the hole? That would narrow down quite a few things.

I didn't measure it, but it felt like a 1/2" i.d.
