Waterworks Board Utilities Panel in our
2008 Coachmen Pathfinder RV
I am still searching for the detailed information about the routing
of the water flow through this valve. If you have further information
please forward to me, firstname.lastname@example.org THANKS!!!
We bought a wonderfully clean, used 2008 Pathfinder in January 2014.
Even though exceptionally clean, it is used and there are some things
that are not quite as I would like. I am sure this would also be true
of a brand new coach!
One item that has my attention is the water system. The regulator
switch does not work correctly so it is forcing my attention. We have
not been able to dry camp but this was not absolutely
necessary so far. Another reason is that I needed to winterize the
coach for the first time and the one and only 'port' has NO residue of
any pink anti-freeze from previous years. As this port hangs down, if
there had ever been any anti-freeze in this line, gravity would keep it
there. It would be really great if there was sufficient explaination in
the manuals to describe the water flow but alas, all detailed
information is completely missing. The picture of the water control
panel in the manual is a different panel than is in our coach!
Waterworks Board Utilities Panel
Our Pathfinder has a Waterworks Board Utilities Panel water
distribution control valve. So far, I have NOT been able to find a
diagram or detailed description of how this routes the water through
the 4 valve positions. I have been able to determine that the valve
an Anderson Brass, 'RV Water Management Manifold' value. Notice the
"ABCO" and "KANTLEAK" on the valve handle. Im guessing that ABCO
stands for Anderson Brass Company. KANTLEAK is an offering by Anderson
Anderson Brass, RV Water Management Manifold
The actual valve of the Waterworks Baord Utilities Panel is an Anderson
Brass, 'RV Water Management Manifold' valve. So far, I have not been
able to find a detailed descriptioon or diagram of the value function.
Anderson Brass web: page http://www.andersonbrass.com/R_V_MANIFOLD.PHP
includes the following picture and text:
Recreation Vehicle (RV) there are six functions that are desired to
service holding tanks, fixtures, and the on-board pump. In
previous RV system designs the water was fed by gravity into the
holding tank with a separate feed for a pressurized fitting from the
city water tap directly to the fixtures. The water could then
be pumped with the onboard pump to the fixtures when not connected to
the city pressure fitting.
Modern RV designs are requiring a higher degree of functionality with
the following six functions:
Fill the On-Board Tanks
Pressurized Water Directly to the Fixtures
Pump from the Holding Tank to the Fixtures
Draw Winterizing Fluid from a Bucket into the Holding Tank, Lines and
Sanitize the Tanks, Lines and Fixtures with the On-Board Pump
Fill the Holding Tank from a Bucket or Stream when City Pressure is not
In the Anderson Brass solution a single valve with internal porting
simplifies the customer interface with a four position handle
to fulfill all five
The Waterworks Board Utilities Panel has four valve positions labeled
CITY FILL - This valve position, routes water from the external water
hose connection to the various water appliances.
- PUMP/POWER TANK DRAIN
- CITY FILL
- TANK FILL
TANK FILL - This position fills the fresh water tank from the external
water hose connection.
SANITIZE/WINTERIZE/DRAIN - I used this position to winterize the water
system. The existing 'port' never created a vaccuum in any position to
suck in the anti-freeze. I fabricated an adapter to the pump inlet side
that I used to suck in the anti-freeze. With the valve in this position
and sucking the anti-freeze directly into the pump input side,
distribution of the anti-freeze throughout the water system worked
PUMP/POWER TANK DRAIN - I have never used this position. When I want to
drain the fresh water tank, I open the fresh tank drain valve and it drains from gravity.
