YACHT SYSTIMS - HULL
SECTION 7
7.1 THRU-HULL FITTINGS
A number of the standard and optional systems used on the
Pearson must penetrate the hull for intake of water. In
addition, scuppers, drains, and certain waste discharge
systems are also brought out below the water line.
Knowledge of the precise location of each thru-hull is
important, and should be one of the first things a new
owner learns about his boat. Thru-hull locations are
illustrated on the next page.
7.2 FRESH WATER SYSTEM
The diagram in Fig. 7.2 shows the fresh water system
installed on your Pearson.
7.2.1 Hot/Cold Pressure Water System
Normal operation of the pressure system simply
involves energizing the WATER PRESSURE circuit breaker on
the DC panel. The pressure pump will then turn itself on
and off whenever a faucet is opened or closed. If the
system is being started up after a long shut down, or 'after
having run the system dry, it may be necessary to perform
the following steps:
Open all faucets, hot and cold.
Energize the “WATER PRESSURE” circuit breaker.
Close each faucet when it starts to deliver a steady stream
of water (cold water faucets first).
The pump should stop operating shortly after the faucet is
closed, and the system is now ready for automatic operation.
7.2.2 Water System Maintenance
The manufacturer's literature supplied at commissioning
provides the necessary information for maintenance and win-
terization of the water system.
