Water Pump And Filter; Fresh Water Fill / Fresh Water Tank; City Water Hook-Up; Low Point Drains - Thor Motor Coach 2011 Avanti Owner's Manual

Your motorhome is self contained, able to carry fresh water in the potable storage tank
and hold the waste water in dual holding tanks for dumping when convenient. Water
connections are also available for a city water hose hookup to an external pressurized
water source.
The fresh water storage tank supplies potable water to all fixtures within your motorhome
by means of a 12 Volt water pump. This pump is located close to the storage tank and is
equipped with a check valve that ensures directional flow away from the tank. The pump
has an on/off switch, which is located on the monitor panel. The pump will automatically
build up pressure and maintain that pressure when turned on. The pump should be
turned off when the fresh water tank is empty or when the motorhome will not be in
use. Continued operation with a dry tank may damage the pump. Your pump has a filter
on the inlet side. This filter should be cleaned after each tankful of water for the first few
uses. To remove the cover press in firmly and twist counterclockwise about one eighth
turn. Pull the screen out of the bowl and rinse clean. Reassemble in the reverse fashion.
For more information check your water pump Owner's Manual located in your Owner's
Information Kit.
The fresh water tank can be filled by an external hose through the potable water fill
located outside your unit. To fill, make sure that the tank and low point drains are closed.
Simply connect the external hose directly to the receptacle labeled "Potable Water" on
the outside of your motorhome. Turn on the external water source and the tank will fill
up. Check the monitor panel while filling the tank to determine how full the tank is. When
full, water may spill back out through the inlet or vent. There is no automatic shut-off for
the fresh water tank fill. When completely filling the tank to maximum water capacity, fill
all water lines and the water heater as well. When possible, traveling with an empty fresh
water tank will provide for more cargo carrying capacity and better gas mileage.
If you choose to use city water directly for your water source, simply attach the external
hose to the inlet labeled "City Water" located on an exterior side of your motorhome.
Now you have a pressurized water supply from the motorhome park or city water supply
hookup. The same water lines are utilized as with the fresh water storage tank and pump;
however, the pump's check valve bypasses both the pump and the fresh water tank. Turn
on the water supply and open faucets to purge any air trapped in the water system.
Some water sources develop high water pressure, particularly in
mountainous regions. These campgrounds or hookup locations may not
have regulated water pressure, which could be considered excessive. High pressure is anything
over 55 psi. Excessive pressure may cause leaks or damage to your water system. Water pressure
regulators are available to protect the water system against high pressures. Check with your dealer
for recommendations of water pressure regulators.
Low point drains are located either in the holding tank compartment. These drains are
used when the system is to be completely cleared of water.
You should sanitize and disinfect the fresh water system upon delivery of the unit and
at least once per year or whenever the motorhome is unused for prolonged periods of
time. This will help keep your water system fresh and discourage the growth of viral and
bacterial contamination, which may be contained in your water supply. Use a chlorine
and fresh water rinse as follows:
