Bow water tank

[jerridsc]

Can someone tell me how the water tank is plumbed, what the openings are for aside from the filler tube opening? (A25)

Thanks,

Off the top of my head...

Typically, a fill fitting, a fitting at the bottom/aft end for the domestic water connection (to the fresh water foot pump) and a fitting for the vent line to outside the hull. The A25 tanks also have that huge cap so you can climb inside and scrub it clean.

JK, but it is a great feature for cleaning the nastiness out.

Can someone correct me if I'm missing something here?

I agree with Jon on the vent and fill, but mine has two holes for output.

The top of the photo shows the two outputs. I converted everything to pex last year.
The right hose goes to the head sink. The left does everything else (the galley sink), including supplying the aux 14 gallon tank barely visible on the lower left of the pic.
The black hose goes down into the bilge and has a plain old drain valve with a common hose fitting. A sill cock. I used to run a hose over the gunwales before I found the bilge plug buried under 40 years of bottom paint. A simple 90 degree plastic drain valve would suffice. Previously, there was no drain, so you either had to siphon, or foot pump the tank(s) empty. I LIKE the drain.

Good call, WillieC. Forgot about the second output.

Mine was plugged off. It must have gone to the head sink but my head sink is long gone.

Yes, mine has two outlets also. I use one for a drain now since the head sink is now plumbed for lake water.

TWO outlets for supply! That helps explain things. Where does the vent line get installed?

Thanks all,

Top port side of tank. Short hose through hull.
