13.6. INTAKE & DISCHARGE THRUHULLS
13.6.1.
This is used for draining the bilge, shower sumps, icebox and supplying and flushing
out the heads. All these supply and flushing points have 1/4-turn valves, which must
be opened only during use. The quarter-turn valve is open when the lever is in line
with the pipe, and closed when it is at right angles.
13.6.2.
Take special care to see that these valves are well-maintained, have a good seal and
work smoothly. Have a wooden tapered plug, of correct diameter at hand, so that they
can be plugged on the outside if, for instance, a seized valve has to be dismantled, or
lubricated.
After hot water has been run through a pipe for the first time, check the tightness of
all the clamps.
NOTE: These recommendations also apply to the cooling system of the inboard engine, if
your boat has one.
