[VAC] Drain Valve

[Charlie/Betty Burke <cbburke@xxxxxxxxxxxxx>]

If the drain valve is original, it was crimp fitted into place and can not be
replaced as you were told.
The drain valve does not attach directly to the tank because the tank is set in
an enclosure that insulates it and allows for heat circulation inside the
enclosure. The outside valve is fitted to a short stub of water line which in
turn is fitted to a stub fitting on the tank itself. While this method was quick
and simple for production it is not a readily field repairable.
The simplest method is to access it directly by carefully cutting a 6" square
hole in the tank enclosure just inboard of the drain valve. This will allow full
access to the short fitting. Cut the crimp fittings off and replace the whole
thing with a piece of low pressure plastic hose with clamps at the tank and the
new valve.
