Water Pumps & Holding Tanks

[Kurt Horvath]

I don't like the sound of blowing air from the coach systems, brakes,
air bags, steps etc. into the fresh water system. Anymore than the
idea of the water system blowing water into the air system.

I think maybe air line fittings with the integral schrader valve, on
each end of the tubing would solve the problem fast, easy and
inexpensive. It would be easy to reattach the tubes in the event you
had to use it.

With the schrader valves you could just air purge the water system
from a cleaner air source than from the coach.

which prevents water from back flowing into the aux air system. In
most coaches that air system includes the air horns, air step , air
bags, driving lights, aux air pump, bulk oil fill, fresh air vent
system and who knows what else. This check valve is a serious weak
link in BB's. If air can be introduced into the water system to blow
it out, water can be introduced into the aux air system in the event
of a check valve failure. The check valve is the only line of
defense. The air regulator will not prevent water back flow and
neither will the purge air switch.

the purifier or water filter where ever it is installed and plug it
or install a ball valve above the check valve which separates water
and air and keep it shut off unless used for winterization.

it the way it is is not an option in my opinion. I have installed a
ball valve. It is cheap and easy and leaves the original system
intact.
