[C320-list] Fresh water system winterization

[John Meyers]

Bill,

I put Whale Ts on each of the hot and cold water lines below the cabinet. I
put a 2-3 inch tube on each T and capped them with removable caps, which I
take off to use a shop vac to suck the water out, while opening and closing
each of the respective H/C faucets including the ones near the transom.
You also will need to switch tanks during the process. I also put a T above
the check valve on the hot water heater, which required me to reposition
the check valve further down away from the opening into the hot water
tank.  (The check valve keeps the hot water from being pushed out while the
cold water is flowing.)  This allows the water to be vacuumed out of the
bottom of the hot water tank.  Nice thing about the whale T is that they
can be swivelled out of the way of the cabinet etc.

Before vacuuming out the water using the Ts I ran the pump the tanks as
much as possible. There is still a couple quarts of water or so left so I
fit a tube to my  vac and reached down thru the tanks' inspection ports to
get as much water as possible out.

Been doing this for many years without putting the pink stuff in the
system.
