(b) The pump-out deck plate is in the anchor well bottom and the vent on the stem head. It
is good practice to flush out the tank with fresh water at every pumpout.
(c) Pump holding tank dry, flush thoroughly and pump dry again. When flushing out, a
deodorizing cleaner should be added before pumping out.
(d) When tank has been pumped dry add 2-4 quarts of ethylene glycol antifreeze to the
toilet and pump through the system and into the tank.
(e) The head is either a Wilcox-Crittenden Head-Mate or a Mansfield Model 751 marine
toilet. For best protection and trouble-free-operation in the next season remove the parts of the
head as per manufacturer's instructions and clean all valves in the head.
(f) In spring, add water to the system and flush thoroughly, then pump out the tank.
(g) Add a deodorant chemical to the system when the system is charged for use.
16.6 Fresh Water Pressure System
(a) The system pump is a Par 36950 or Raritan. For full details on maintenance and spare
parts, see the manufacturer's instructions.
(b) Fresh water tanks are situated on port and starboard, connected by a leveling pipe with a
shut-off valve at each tank. These can be used to isolate either tank from the supply system if
required. The supply is drawn from the leading pipe. Each tank has two inspection ports on the
top. The tanks should be drained during the lay-up and winterized as follows;
Disconnect the grey pipe leading from the T~piece connecting the two tanks to the water
pump. Drain almost all water from both tanks. Leave a couple of gallons in each, by
turning off their respective gate valves. Reconnect water pump pipe at 'T'. Add one
gallon of potable antifreeze to each tank. Open both faucets in the ‘Hot' position and run
pump until antifreeze mix emerges. Change faucets to "Cold" position and run mix
through.
(c) After pumping out the tanks, disconnect all hot and cold water lines at the lowest point
(see detail No. 19) of the system and let any water left in the tanks and lines drain into the bilge.
Be sure that both water tank shut-off valves in the leveling pipe and the supply pipe from the
pump to both the hot water tank and faucets, the hot water supply pipe and uncouple the supply
pipe to the hot water tank and drain.
(d) The pressure pump should run very briefly with all cold water taps open to force out any
remaining water. CAUTION: Do not run the pressure pump more than a few seconds or damage
may be caused by running it dry.
(e) Pump the hand pump as well as the sea water pump (if provided) several times to expel any
water.
(f) Leave all faucets open once system is shut down.
