Plumbing Systems

5.1 Fresh Water System

General

The fresh water system consists of a potable

water tank, distribution lines and a distribu-

tion pump. The pump comes with an auto-

matic pressure switch and is located in the

stern bilge. An in-line strainer located near

the pump protects the system from debris. A

labeled deck plate located on the gunwale

allows for filling the tank.

Operation

Fill the water supply tank slowly through the

labeled deck plate. After filling the water

tank, partially open all faucets. The fresh

water system switch on the helm panel

should be "ON." Allow the pump to run until

purging all the air from the system and a

steady stream of water flows from each out-

let. Next, turn off the faucets one by one. As

the pressure builds, the pump will automati-

cally shut off.

After properly priming and activation, the

water system will operate much like the

water system in a home. An automatic pres-

sure sensor keeps the system pressurized.

Recently filled tanks or tanks used for an

extended period may cause air accumula-

tion at the pump and the system may need

to be re-primed.

Whenever unattended, place the fresh water

system switch in the “Off” position.

Sink and Shower Operation

To use the galley sink, head sink or shower,

turn on the fresh water system. The head

sink faucet is also the shower spray head.

To use, lift the spray head off the sink and

turn the water on. Some minor variations in

the water temperature and pressure may

occur as the pump cycles. The sinks drain

overboard.

Water drains from the shower to a sump

pump system located in the bilge below the

cabin floor. An automatic float switch in the

shower sump controls the pump. After show-

ering, let the cold-water flow for a while to

flush the drainage system of soap residue. It

is essential to clean the shower drain

strainer regularly. Periodically inspect and

remove accumulated debris from the sump.

Water Heater

The water heater is located in the machinery

space. All heaters have a thermostatically

controlled AC element at the heater, acti-

vated by a circuit breaker located in the AC

panel. A high-pressure relief valve protects

the system from excessive pressure. Purge

! CAUTION

Do not fill the system with anything

other than water. Contamination of the

system with fuel or other toxic fluids

may necessitate the replacement of

components.

! WARNING

Do not confuse fuel-fill deck plates

with the water or waste-fill deck

plates. If gasoline or diesel acciden-

tally is pumped into the water or waste

tank, do not attempt to pump it out

yourself. Water and waste pumps can

cause a fire or explosion. Have the

fuels professionally removed and the

components of the fresh water system

replaced as necessary.

! CAUTION

Do not allow the fresh water pump to

run dry. Empty fresh water tanks will

cause the pump to stay on as the

pump works on-demand and will not

shut off automatically. This can result

in damage to the pump. Always turn

the water pressure switch "Off" when

not in use.
