As with any mechanical system, the 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
faucet's 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 the 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.
