PTIONS
The even flow of water gives better control of hot
water adjustment at the faucet.
The reduced on/off cycling reduces noise from the
pump motor, and from shock pressures (pipe
hammer). It also reduces battery drain, and gives
longer pump life.

The water distribution manifold directs fresh water
from the water tank and the water heater to the
various equipment throughout the yacht. The
manifold located in the bilge forward of the water
tank and between the water heater and the port
fuel tank.
If away from the boat for an extended period of time
it is suggested that you relieve the hose pressure
of the fresh water system by turning OFF the
FRESH WATER PUMP breaker on the DC main
distribution panel and then opening a faucet on the
boat.

RESSURIZATION
Water system pressure is regulated by a pneumatic
accumulator bottle (See figure 7.4.1) located in-line
on the cold water outlet from the pump.
The accumulator tank smooths water flow and
reduces on/off cycling of the pumps by lessening
the variation in pressure and flow between the pump
and the outlets in the system.
