Plumbing winterizing question - davidkerryedwards - 07-30-2006 01:44
Some of you may recall I posted a question about a problem I was
having with no water thru the hot water lines. I figured out that
problem after talking to Tom Warner. The valve labeled 'Hot Water
Drain' in my coach is actually a hot water tank/line fill valve. If
that valve is not depressed with the cable control, water does not
enter the hot water lines. Once depressed, everything worked fine.
But I have a conceptual question about winterizing. When the air is
blown into the system via the electric valve, how are the hot water
lines blown out since the air has (?) to pass thru the hot water
heater before pressurizing the hot water lines? It seems the hot
water heater would absorb a lot of pressurized air before there was
enough oomph to blow out all the hot water lines.

Kerry your fill valve is on the outside where the water connection
is. It appears that you are not following the instructions on the
drop down door where your air fill and winterizing valves are. You
have to have both valves in the normal position if you are going to
fill your tank .

Yes, the water tank fill valve is outside, but inside is a spring
loaded valve built into the water lines which allows the hot water
heater tank to fill. It is labeled as a drain valve behind the drop
down door inside but the hot water heater tank will only fill if the
long arm compresses that valve. If that valve is not compressed there
is no water in the hot water lines either from the water tank or from
city pressure.
