Winterization
Drain the complete system both as a protection against frost damage and
to avoid the growth in the pipework of bacteria that could cause unpleasant
smells.
HAZARD RISK:
Seacocks opened by mistake. In case you leave the toilet disassembled
and if the sea cocks are opened when the boat is afloat, water will flood in
by causing the sinking of the boat and the possible loss of life. Therefore, it
is indispensable to attach a warning notice to the seacocks and, if possible,
wire the seacocks shut. Remember to attach warning notices!

that the product penetrates the whole toilet system If, for any reason, an
anti-freeze compound is employed it will have to be a glycol-based one.
