DRAIN VALVES
The 30 ft Front Bed
model has two low point
drain valves accessed by
removing the rear dinette
seat cushion and reaching
through the hole cut in the
seat bottom. It has the fresh water tank drain, a white petcock, on the exterior
tank pan under the trailer. The hot and cold water line low point drain valves
on the 27 ft. and 28 ft. are located on exterior of the coach for easier access. If
you look under the trailer, you will see a “box” that is a few inches lower than
the trailer frame. This “box” or pan supports a water tank. The line drain valves
will be the two brass pet cocks on the bottom of the pan. The 23 ft and 25 ft.
front bed model has the low point drain valves located inside the roadside rear
exterior access door. The 19 ft. line drain valves are located in two different
places. Two are located under the rear bed and access has been provided in
the bed top under the mattress. (If you are long and lanky, they can be reached
through the exterior storage compartment.) The other two line drain valves
are located under the roadside dinette seat. Remove the cushions to access a
removable panel in the lounge top. The 16 ft model has two drain valves that
are located under the roadside dinette seat. Remove the cushions to access a
removable panel in the lounge top.
Open these low points drain valves and use the hitch jack to raise and lower the
trailer front end to drain the water out of the hot and cold water lines.
To Empty Fresh Water Tank
On the 23 ft, 25 ft, 27 ft, 28 ft, and 30 ft. models, a large valve on the fresh
water tank pan under the trailer drains the water fresh tank. On these models
an additional 1 ¼” drain plug is located on the bottom of the tank inside the
galvanized “box”. The plug is accessible by removing an inspection plate close
to the petcock that can be seen on the bottom of the tank support pan. There
may be a little Styrofoam insulation covering the plug that should be carefully
removed and replaced. The water tank drain valve on the 16 ft. and 19 ft. model
is located under the roadside dinette seat; remove the cushions to access a
removable panel.
Pumping the water out with the self-contained water pump also empties the
fresh water tank. Simply turn on the pump switch and open a couple of faucets
until the water will no longer comes out.
Note: For winterizing purposes, only the large tank drain valve needs to be
opened to drain the fresh water tank.
