ALWAYS close seacocks when toilet system is not
in use (even if boat is unattended for a brief period.

quality. Screw-to-close gate valves are not
recommended. Failure to comply can result in
flooding which can cause loss of property and life.

HAZARD OF FLOODING – If toilet is
connected to ANY through-the-hull fittings, ALL
flexible hoses must be of marine sanitation quality
and must be secured to ANY fittings (such as
those at seacock, vented loop or toilet) with two
stainless steel, worm-drive hose band clamps at
each connection. Connections MUST be checked
frequently for integrity. Failure to comply can result
in flooding which can cause loss of property and
life.
WARNING!
HAZARD OF FLOODING – If toilet rim
is below the waterline at ANY time (during any
conditions of heel, load or trim) and is connected
to ANY through-the-hull fittings, properly
positioned ventilated (vented) loops MUST be
installed in discharge piping to prevent potential
back siphonage of seawater into the boat. Failure
to do so can result in flooding which can cause
loss of property and life.
