Cold Weather Plumbing

[Tom Warner]

Have you guys really thought this out? Routing hot water from the
hotwater tank will mean the addition of new hotwater lines from two
sides on the PTs and one side on the FCs as well as pumps and some
way to sense the temperature to control things. How would you protect
the back of the shower using this method for instance?

In the PT you have actually two water branches one to the kitchen
side and one to the bath. On most forward controls you have
everything on one side except for those floor plans where the kitchen
is on the opposite side to the bath. I never did sit down and figure
out how to do it for the FC.

There are two problems, first winterizing the coach for storage in
the winter, and secondly using the coach in freezing weather. The
first case is a little easier to solve for the PTs. Install a bypass
using 3 ball valves and then injecting the antifreeze at the outside
hose connection leaving the sporlan valve turned on for city water
bypassing filling the water tank. Purge the water from each line and
everything is protected.

Winterizing the PT for freezing weather use is actually not that
difficult either. As I recommended to 'Ernie installing small fans
in various places to route room air into the cavities that are not
open to the air and then furnishing another register for the air
return appears to me to be the practical way to do this. . On my PT
the underside of the body is already heavily foamed so I believe with
this simple addition the pipes would be protected.
