On Pegasus all 3 tanks have a common vent that exists at the head sink. I
wouldn't want an external vent for my potable water, due the possibility of sea
water contamination. I fill my tanks starting with the port tank. Which is the
farthest from the vent.

Water tank x-connect
On my LF38, all three tanks have their own individual vent as they should. The
vent line follows the inlet hose and exits the hull just below each fill
connection on the deck. The original vent lines are 3/8" gray plastic piping.
A good venting system is necessary to get good flow into and out of the tank as
well as insuring that the water pump does not pull a vacuum on the tank and
cause it to implode--I have seen this happen on poorly vented holding tanks
when emptied.

So I'm doing some water tank work and I've confirmed what I already suspected.
My tanks are cross vented to one another through a low point loop. It appears
that I could in theory fill all my tanks from one deck fill port despite having
a fill port for each of my tanks. I'm thinking that tracking tank level is a
challenge when they are all sluicing between one another.This doesn't seem
advantageous. Why would the manufacturer do this. Is there a problem with me
undoing it?Josh Muckley
