4. Allow closed system to stand for three
hours.
5. Drain the hypochlorite solution from the

The Everpure EN-1 Water Purifier (standard
on International models) is located under the
Water Drain Valve (Int'L Center Bath)
galley sink. It will remove all dirt and col¬
loidal matter, and eliminate most chlorine,
phenol and similar odors and tastes while
delivering sparkling taste-free water for drink¬
ing and cooking. The filter is connected to the
cold water line only. The purifier is not
guaranteed to remove the tastes and odors of
iron and sulphur. To remove these tastes,
chlorinate the water supply. Super chlorination
will precipitate dissolved iron, and the purifier
will then remove the formed chlorine salts. To
purify any questionable water add 1 tsp. of
chlorine (ordinary household bleach) per 10
gallons of water to the water tank. 414 tsp. for a
45 gallon tank. We recommend the use of
tablets available at Wally Byam Stores. The
quality of the water never varies even at the end
of the filter pack life, however as the minute
pores slowly fill up with impurities, this will
gradually reduce the rate of flow until it is
necessary to change the filter. Instructions are
in each box, and we advise buying two at a

The water pressure regulator is on the road¬
side of the rear trunk in International rear
bath models, below the bed in International
center bath models and in the aft roadside
wardrobe of Land Yachts. It protects the
plumbing inside your-trailer, regardless of the
variation in city water pressures. The pressure
at the faucet is kept constant.
The water system has built-in drain valves to
protect it from winter freezing. For complete
details see Storage and Winterizing, page 35.
