PLUMBING & BATH FEATURES
6. The water pump is now ready for automatic operation. The pump will run when a faucet is open
and stop when a faucet is closed.
7. Never allow the pump to run for long periods of time without water being present in the supply
tank, as doing so may cause physical damage or blow fuses.
If water does not flow when a faucet is turned “on” while using the demand system, use the following
troubleshooting chart:
SITUATION SOLUTION
Pump running – no water 1. Fill tank
2. Clear the water line to the pump
Pump doesn’t run 1. Check the pump switch
2. Check the 12-volt fuses
3. Check the electrical connections
4. Check the battery
All the water should be drained from the freshwater system when the unit is not in use for extended
periods. For more detailed information regarding the water pump, one should refer to the water-pump
manufacturer’s brochure in your Allegro Bus Owner’s Information Package.
CITY WATER CONNECTION
When connecting your unit to city water, use the water hose manufactured and labeled for potable
water service—this will assure that the hose selected for use will not alter the taste of the water (Figure
13-6).
To connect the city water supply, connect one end of the hose to the city water
supply.
Once the city water fill valve is opened, water is supplied to the freshwater
system including the hot water heater, faucets, and toilet. Turn “on” the water
supply and open all of the faucets to clear any trapped air within the plumbing
lines within the motor home.
Once any air pockets have purged from the water lines and water flows freely,
close all of the faucets. The city water supply is pressurized; therefore, the water
pump is not needed when the water system of the vehicle is connected to the
city water system.
If city water pressure is more than 60 psi, it is recommended to use a water
pressure regulator to prevent any damage to the motorhome.
