2022 Coachman Concord CLASS C MOTORHOMES Plumbing General Information Owners Manual

PLUMBING OVERVIEW

An RV’s plumbing system has basically two water systems: the freshwater system and the wastewater system. The freshwater system consists of those items which are used to deliver water for your use while the wastewater system is made up of the drains and tanks that store and remove water that has been used. Components of the plumbing system consist of strong, lightweight, corrosion-resistant materials that provide long life and easy cleaning. By following the instructions outlined within this manual, you can expect efficient operation with a minimum of maintenance.

MAINTENANCE AND TROUBLESHOOTINGRoad 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. If left unchecked, water leaking from a plumbing joint can cause considerable damage. A leak in the freshwater system should be suspected if the water pump is running and all faucets and valves are closed. When the leaking fitting has been identified, attempt to stop the leak by tightening the fitting. DO NOT over-tighten. Plastic fittings rarely need to be tightened with a wrench. If these fittings leak after tightening by hand, disconnect the fitting and check for dirt, scale, or other foreign substances 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 the 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, water pump, and all piping. Be sure to follow the winterization procedures outlined in this manual. Also, be sure to discuss with your dealer or repair center any additional precautions that should be taken to winterize your RV’s plumbing system. Local climates vary and winter maintenance needs may be affected. Be sure to read the literature supplied with plumbing components, such as the water 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, it is best to have your dealer or a qualified plumber who is familiar with the RV water system inspect the system and perform any repairs needed.
NOTICE
If your faucet is exhibiting low or diminished water flow, disassemble the faucet and clean the aerator (filter screen) thoroughly.

BASIC TROUBLESHOOTING TIPS

Limited or no water flow at a faucet:

• If utilizing onboard water, verify the water pump is ON.
• If utilizing onboard water, verify there is water in Fresh Water Tank.
• If utilizing City Water connection, verify spigot is turned ON.
• Verify faucet aerator (filter screen) is clean and NOT clogged.
