Understanding the Dometic Model 147 Components
The Dometic Model 147 is a popular choice for RV and marine sanitation systems. Understanding its core components is crucial for effective troubleshooting and repair. Let's break down the key areas:
1. The Bowl and Seal:
- Toilet Bowl: The main ceramic bowl where waste is collected. Cracks or chips may require a complete bowl replacement.
- Bowl Seal: This rubber gasket creates a watertight seal between the bowl and the base. Leaks often indicate a worn or damaged seal.
- Flush Valve: The mechanism that controls the release of water for flushing. A faulty flush valve can lead to inefficient flushing or leaks.
2. The Pump and Tank Mechanism:
- Diaphragm Pump: This is the heart of the system, responsible for pumping waste into the holding tank. A faulty pump can cause the system to fail entirely.
- Pump Motor: Provides the power for the diaphragm pump.
- Pressure Switch: Controls the pump's operation, activating it when the flush is initiated.
3. The Holding Tank and Fittings:
- Holding Tank: The tank that stores waste until disposal. It's crucial to ensure this is leak-free.
- Tank Level Sensor: Indicates the level of waste in the holding tank.
- Outlet Valve: Controls the release of waste from the holding tank.
4. Other Essential Components:
- Flush Lever/Button: The mechanism that initiates the flushing process.
- Water Inlet Hose: Supplies water to the toilet for flushing.
- Various Gaskets and Seals: Numerous smaller gaskets and seals throughout the system ensure watertight integrity.
