In the late 1970's and early 1980's, some RV (brand) club members were
painting the club numbers on the roofs of R.V.'s in an effort to prevent stolen
trailers which was happening
quite a bit back then. This was a way of tracking their trailer by club
numbers incase the
vin numbers were destroyed. This may have been another place that the
original owner of your trailer added their numbers for positive identification of
their trailers.

This is a very good question and I can answer it for you. I have a 1977 SS
and have the same configuration.
The middle valve is simply a low point cold water drain line for winterizing
and this also applies to the right valve in the compartment for hot water
drain. These are only opened when you are winterizing the trailer and
eliminating all water from the system. Of course, you can open them briefly if you
want to drain possible sediment out of the pipes periodically.
The left valve (closed) bypasses the on board water pump and tank from the
trailer water system if you are hooked up to city water. When this valve is
(opened), it will allow water to flow freely into the pipes to pressurize the
trailer from the pump. In other words, this valve will only be opened if you
are using water from your tank without city water hook ups because it allows
water to pressurize from the cold water side to the trailer from the pump.
There were originally check valves in the lower city water inlet that
prevented water from coming out when the pump system was used. I now use a cap that
screws into the bottom which holds the water tight while using the demand
pump.
Keep in mind that these trailers originally had pressurized onboard water
systems that relied on an air pump to pressurize the water tank. While dry
camping, this allowed the water to flow from the system when a valve was opened
for water. Originally, the tanks were used with the city water system and
water would fill the tank and
would be used from the tank even with city water. Through the years, many
have converted to the demand
pump which simply draws water from the fresh water tank when a valve is
opened. This is not a pressurized system now by using a demand pump. Since this
is the case, there is a need to bypass the water system when hooked to city
water. Some of the earlier trailers have been modified and a cut off valve has
been added to bypass the tank/pump system when connected to city water. I
labeled my connections in the compartment above the lines so I do not have to
think too hard each year while winterizing!
