4P: Head Systems
4P1: Overview
The head system on this boat is reliable, straightforward, and easy-to-use.
First, a note about discharge of sewage:
It is forbidden to discharge untreated sewage in inland US. waters, an area
that includes all US. waters in which this boat operates. The boat holding
tank must only be emptied at proper pump-out stations if it is in US.
waters. (This rule does not apply in Canadian waters. However, in Canada,
courteous practice dictates that the holding tank be dumped only when
outside confined marinas or bays, as we are sure the reader agrees!)
The boat is equipped with two Master-Flush Marine heads. These heads each have a
separate macerator pump which macerates waste and puts it either into one of two holding
tanks or directly overboard, as determined by the setting on a Y-valve in the head plumbing
lines. The holding tanks are emptied either of two ways: by operating an overboard macerator
pump controlled at the DC power panel, or by pumping it using a shore side pump out station
through the boat's side-deck pump out fittings.
4P2: The Dometic Masterflush Heads
These premium heads are easy to use, odor free, and very
reliable. They work with a macerating pump for each head.
These heads use about a pint of fresh water from the ship’s
supply with each flush.
Each head is operated by a pair of “rocker” switches on the
nearby vanity.
Normal Flush: Press the left switch (the one with a cartoon-
toilet with the arrow down and water in it to empty the head
and add water to the bowl thereafter.
Add water: Press the top of the right hand rocker switch and
release when enough has entered.
“Dry Bowl”/Empty Toilet: Press the bottom of the right hand
rocker switch and hold until the bowl empties completely!
Only things which were eaten or drunk or the toilet paper supplied
with the boat should be put in the heads! Facial tissues, tampons,
and other foreign matter will clog the system. If these heads are
used properly, they are very reliable. Failures are virtually always
due to mis-use!
