[C38] Fresh water tank vent

[Steve Smolinske]

Peregrine has a vent hose running from the top of the tank to the
starboard side cabinet in the main salon and then up through a vented
stanchion.

Our water tank has a vent in the fill cap on the tank itself.  I didn't
install an outside vent for two reasons.
 
1.    I didn't want bugs, salt water or debris entering the vent from
outside the boat.
 
2.    I installed a crossover with fill valve in the forward end of my
bilge which goes between the cold water supply to the head and the
service hose going from the water tank to the water pump.
 
By taking the tank cap off in the v-berth and opening the crossover
valve, we can fill our tank from inside the boat where there is no bird
droppings, etc.  When the tank is full and overflowing into the bilge,
we close the valve in the bilge and replace the vented tank cap.  The
vent hole in the tank isn't sufficient for venting when pressure filling
so it must be removed during the fill process.  I could have installed
an auxiliary vent with an inline filter but since the process we use is
so simple and easy, I decided to forgo the auxiliary vent.
 
Since we the time we bought our boat, the water fill deck fitting has
never been off.  We installed a "whole house" water filter in our anchor
locker where we also installed a camper type water connection which
includes a built in pressure regulator.  The water fill is on the port
side mirror image to the manual bilge pump so it looks like a factory
fitting.  The hose fitting on the boat has a protective cover when a
hose isn't attached so everything stays very sanitary.
 
Filling the water tank with the crossover is very easy, much easier and
more sanitary than trying to drag a hose to the foredeck.  Since the
shore water supply has to go through a whole house filter, our complete
water system is protected from contamination.  We use a carbon filter
which also improves the taste of the water.  If we are at a dock with
shore water connected, we just top off the bow water tank before we
disconnect the water hose in the cockpit.
 
The filter and crossover projects are both very inexpensive and easy to
do.  All materials were purchased from either Home Depot or Lowes.   We
used a plastic crossover valve because it sits in the bilge with salt
water and the plastic won't corrode like a brass valve will.

	Hi all,
	 
	Estancia came with no vent on the water tank. Is the same case
on all C38s?? I just have a piece of hose with a check valve and that's
it, so, I have to fill the tank from the inside so I can check the
level. I want to install one, but because of the low sheer line, I'm
concerned about salt water coming inside the vent to the tank. Have
anyone added an external vent?? 
	 
	Any comments will be really appreciated!
