Regarding the vent line, mine goes up a few feet above the tank and then
loops back down draining into a larger diameter piece of tubing and then
down into the bilge. The small tube draining to the larger tube creates
a simple vacuum break to prevent siphoning and makes sure the overflow
goes into the bilge. Also, since the drain loops so high, the tank will
not drain when the boat is heeling steeply.

My tanks vented into a false bulkhead forward (just aft of the sink)

Clearly, overfilling the tank would result in a lot of water going
everywhere.
The inspection ports were clear plastic Beckson deckplates. They are
not designed for internal pressure. Consequently, by overfilling, you
cause the o-ring to leak. I replaced them with stainless steel access
plates. You can read about it somewhere on my blog
http://thesailinglife.blogspot.com. If anyone is interested, I’ll
find the link.
I’ve moved the vents to the bilge, but have come up with a better idea
with a loop in the vent and drain to bilge – running the lines to the
deep part so I don’t fill up all the dips and bumps around the mast.
A better way would be to vent into a sink, but that’s too difficult.

I had this same problem on my bow tank; the inspection port
leaked. I had to replace the whole port as it has somehow warped
and a new o-ring still did not make the seal.

Barbara,
I just ordered and installed a new set of O-rings for the
inspection ports on my water tanks, since most
of them leaked when the tanks were filled to the top. My salon
tanks have three inspection ports each,
but only one per tank is accessible through the slide-out
plywood bunk extension piece. In other words,
when you lift the settee cushion you only see one access port,
reached through holes cut in the plywood
covers. However, removing the slide-out plywood pieces
covering the salon tanks (underneath the settee
cushions) reveals two more inspection ports per tank, one for
each baffled compartment of the tank. If
your boat also has these check them for leaks around the
screw-out center piece. If they’re leaking,
replace the O-rings on all the ports on all tanks.
My inspection ports were all made by Beckson Marine,
http://www.beckson.com <http://www.beckson.com> . I think they call
them “deck
plates.” Beckson was quick and reasonably priced about sending
new O-rings. To order by phone, call Cindy
at 203-333-1412 to order.
Good luck,
Tor
