Using Fresh Water (Potable) System
1. Fill the fresh water tank(s)until water is seen at the water
fi ll vent.
2. At the ship’s main service panel activate the fresh water
system breaker. This will energize the water pressure pump
to send fresh water from the potable water tank through
the cold water lines terminating at the various faucets and
related components.
3. Open a faucet. Water pressure should be present.
Opening each faucet for a few seconds will purge any air
in the system especially in cases where the fresh water tank
has run out of water. When water is running at a particular
faucet it is not unusual to hear the water pump activate as
it is trying to build up the pressure required in the system.
Soon after the faucet is turned off the fresh water pump
sound will end indicating the fresh water system is now up
to specifi ed system pressure.
Note: If the fresh water pressure pump continues to run
long after the faucets are deactivated check for fresh water
system leaks.
Note: Related to the above periodically check the fresh
water monitor for fresh water tank levels. Do not run
pressure water pump with system dry as water pump
component damage will occur.

Fresh Water Pressure Pump
In theory the fresh water pump system provides water
pressure when dockside water is not available or used. Once
energized the pump is automatic. It will shut down once
system pressure has built up and will automatically start
after a faucet is opened. The fresh water pump and fi lter
are normally located under the forward berth.
The fresh water pressure pump features a removable
strainer basket fi lter which collects any debris which has
entered the fresh water system. The clear strainer cover
highlights any debris.
To clean the basket make sure the pressure water pump
is off at the ship’s DC control panel. Unscrew the clear
cover to access the strainer basket. Remove the strainer
basket, clean, rinse with fresh water and reinstall basket
and cover. Do not overtighten or use tools. Turn on the
pressure pump breaker and check for leaks.
Note: It is recommended that the fresh water pressure
pump breaker be fl ipped to the “off ” position when
leaving your boat to help prevent damage should a
leak develop in the hot or cold water system.
Note: In freezing climates make sure the fresh water
system is winterized to prevent damage to hoses and
components. Contact your Regal dealer since only
special alcohol based products like “Winterban” are
to be used in the system. Never use automotive type
antifreeze since it is poisonous to the human body.
