09 Plumbing & Bath Features

Kitchen Sink

For the sink, cleaning care consists of washing only with mild detergents and water and using a soft cloth for subsequent drying and polishing.

Shower

The TIFFIN GH1 features a wet bath. This includes a shower that also houses the toilet. There is also a removable, magnetic shower curtain and a removable shelf in the shower.

The shower utilizes a shower miser, which allows the fresh water to circulate until it reaches the desired temperature before coming out of the shower nozzle. Once the water reaches the desired temperature, the blue line will turn white.

 

Water Pump

The water pump is used to pressurize the fresh water system when the unit is not connected to city water.

To start the pump, follow these instructions:

Fill or partially fill the freshwater tank supply

Open the kitchen and bathroom faucets.

Turn the water pump switch to the “ON” position and allow the water to fill the water line

Close each faucet after it delivers a steady stream of water (close the cold-water faucet first). Leave the hot water faucets “ON” until they deliver a steady stream of water.

The water pump should stop running once all the faucets are closed.

The water pump is now ready for automatic operation. The pump will run when a faucet is open and stop when the faucet is closed.

Never allow the pump to run for long periods of time without water being present in the supply tank. Doing so may cause physical damage to the components or it may blow fuses

All the water should be drained from the fresh water system when the unit is not in use for an extended period of time.

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

Pump doesn’t run                          2. Clear the water line to the pump

                                                       3. Check the pump switch

                                                       4. Check the 12V fuses

                                                       5. Check the electrical connections

                                                       6. Check the Van battery

City Water Connections

When connecting your unit to city water, use a 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.

When connecting your unit to city water, use the water hose and connect to the city water port. While doing so, make sure the blue handle is turned to CITY

Filling Fresh Water Tank

The fresh water tank has a capacity of 26 gallons.

To fill the freshwater tank, make sure the blue handle corresponds to the POWERFILL TANK

Sanitizing

Sanitizing Hot and Cold Fixtures and Fresh Water Tank

To assure complete disinfecting of the freshwater system, it is recommended that the following procedures be performed on a new system, on one that has not been used for a length of time, or one that may have become contaminated. This procedure is also recommended before long periods of storage, such as during the winter months:

• Drain the freshwater tank by opening the drain valve. All of the faucets should be in the closed or “off” position.
• Prepare a chlorine solution using one gallon of water and one-half cup of chlorine bleach (5% sodium-hypochlorite solution). Prepare enough of the chlorine solution to administer one gallon of solution for every 15 gallons of tank capacity. Concentrations greater than 50 ppm may damage the water lines and/or the tank. • Once the freshwater tank is empty, close the drain valves in the water tank.
• Pour the solution in the gravity fill which is located on the rear of this coach.
• Turn “on” the water pump. On the sewer board turn the blue handle valve to “normal” position and turn the red handle valve to “normal” position.
• Open each faucet, in turning “on” both the hot and cold faucets and flushing the toilet until all of the air has been purged from the pipes and the water runs freely. The entire system will then be filled with the sanitizing solution.
• Allow the 50 ppm disinfecting solution to stand in the system at least four hours.

Sanitizing Hot and Cold Fixtures Only (Not Fresh Water Tank)

• All faucets should be in the closed or “off” position.
• Prepare a chlorine solution using one gallon of water and one-half cup of chlorine bleach (5% sodium-hypochlorite solution). Concentrations greater than 50 ppm may damage the water lines.
• Connect one end of the vinyl hose to the inlet valve on the sewer board; place the other end of the hose into the solution that has been prepared.
• Turn “on” the water pump. On the sewer board turn the blue handle valve sanitize/winterize and turn the red handle valve to bypass.
• Open each faucet, in turning “on” both the hot and cold faucets and flushing the toilet until all of the air has been purged from the pipes and the water runs freely. The entire water lines will then be filled with the sanitizing solution.
• When the sanitizing process is completed, turn the water pump “off”.
• Allow the 50 ppm disinfecting solution to stand in the system at least four hours.
• Drain the system and flush it with freshwater. The water lines will need to be flushed with water repeatedly, if necessary, until there is no chlorine taste or smell left in the system. To remove any excessive chlorine taste or odor that might remain, prepare a solution on one quart of vinegar to five gallons of water. Repeat steps four, five and six to run the solution through the water lines. Drain the system and flush with freshwater.

Fresh Water Lines

Check all of the plumbing connections for leaks at least on an annual basis.

If the water pump runs when all faucets are turned “off,” check for a possible leak. Be sure that the drain valves are closed. Connections at the kitchen and bathroom faucets normally seal by hand-tightening them and then making an additional half-turn with a wrench.

If a fitting leak persists, disconnect it completely and visually inspect it for mineral deposits or foreign material stuck on the sealing surfaces. Clean the surfaces thoroughly and reinstall the fitting.

General Information

The waste drainage system was designed to provide adequate and safe storage and/or disposal of waste materials. All of the materials used in the fabrication of this system are tested by a nationally recognized testing laboratory. The drainage system uses plastic piping and fittings connected to the sinks, toilet, and holding tanks. This plumbing permits the drainage of these fixtures to an outside termination. The vehicle should be reasonably level for best operation of both of the wastewater systems.

Toilet

The toilet features a push-button flush.

The toilet (Figure 11-2) operates with water from either the fresh water tank with the water pump “on” or the city water supply. Before using the toilet, add water to the bottom of the tank. Refer to the “BLACK WATER TANK” instructions.

The toilet flushes waste directly into the black-water holding tank

The toilet should be cleaned regularly for maximum sanitation and operational efficiency. Clean the toilet bowl with a mild bathroom cleaner.

Black Water Holding Tank

Wastewater Disposal

To disposal of wastewater from the black tank is accomplished by removing the black water tank from its holding position in the coach, as shown, and disposing of it in a certified black water reservoir.

 

Sewer Connection and Camping

While using the Van, it is important to keep the black/grey-water holding-tank gate valve closed at all times, except when dumping. This allows an ample amount of liquid to remain in the tank to provide a smooth flow through the gate and drain valves when dumping. Sufficient liquid in the tank causes a swirling action that should take any accumulated solid wastes with it.
