If motorhome is equipped with a washer/dryer turn the washer ON and let run until antifreeze is visible
and continue to run for 15-20 seconds. Turn the cycle selector to rinse cycle to ensure the antifreeze
gets into the pump to protect it.
•
Turn OFF the water pump.
•
Pour one cup of antifreeze in every drain to protect the P-traps.
Before using the system again in warmer weather, completely flush the systems with water, flush the toilet,
and sanitize the entire fresh water system. When using the RV during cold weather, and water in a tank or
drain line should happen to freeze, you should take immediate steps to thaw it before damage to the system
occurs. DO NOT continue to use the water system components if such a condition exists. If damage has
occurred, make sure to have it repaired before using again.
WATER SYSTEM, MAINTENANCE & TROUBLESHOOTING
As with any mechanical system, your plumbing is subject to the development of problems. Most of these
problems can be greatly reduced if not altogether eliminated by following a schedule of planned inspections
and maintenance. Neglect of proper maintenance procedures is the usual cause of most water system
problems.
Road vibrations and shocks, as well as excessive pressure from some city water sources are the main
physical causes of water system damage. It is important to inspect all plumbing joints and fittings often for
cracks and leaks. Water leaking from a plumbing joint can cause considerable damage if left unchecked.
A leak in the fresh water system should be suspected whenever the pump is running and all faucets and valves
are closed. When the leaking fitting has been identified, attempt to stop the leak by tightening. DO NOT over
tighten. Plastic fittings rarely need to be tightened with a wrench. If these fittings leak after being tightened by
hand, disconnect the fitting and check for dirt, scale, or other foreign substance which may be causing the
leak. Clean the fitting thoroughly and reinstall. If leaking persists, shut off the water supply until the fitting can
be properly replaced. Check with your dealer for correct method of replacement, and replacement parts.
Proper winterization procedures of plumbing systems will normally be all that is necessary to prevent the
damage caused by freezing. Freezing damage can harm any component of the system, including the water
tanks, toilet, pump, and all piping. Be sure to follow the winterization procedures outlined in this manual. Also
be sure to discuss any additional precautions that should be taken to winterize your water systems with your
dealer. Local climates vary; and winter maintenance needs may be affected.
Be sure to read the literature supplied with plumbing components, such as the pump, for troubleshooting tips.
Also remember that it is possible for an electrical problem to cause water system problems. Lack of power to
the pump can be caused by a variety of reasons. If you are unsure of how to locate and/or repair a plumbing
problem, contact your dealer.
