oil-resistant 0 ring forms a liquid-tight seal between
the water-discharge connections of the cover and
bowl casing when the cover is closed. The lower end
of the bowl casing’s water-discharge connection is
flanged to the water-discharge line. The water-
discharge line directs water into a sump tank. The
water-discharge line contains a flexible pipe

This flexibility allows for safe passage through the
