Key Components of the Dometic Model 147 Sanitation Toilet
The Dometic Model 147 toilet system comprises several essential components, each playing a crucial role in its proper functioning. Let's explore these key parts:
1. Toilet Bowl and Flange:
- Toilet Bowl: The ceramic bowl is the primary component, where waste is collected. Replacement is usually only necessary in case of serious damage.
- Flange: The flange seals the toilet bowl to the base, preventing leaks. A damaged flange is a common cause of leaks, and replacing it might be necessary.
2. Sealing Mechanisms:
- Sealing Ring(s): Several seals prevent leaks between the bowl, the base, and other components. These are wear-and-tear items and should be inspected and replaced periodically or if leaks are detected.
- Valve Seals: These seals ensure proper operation of the flush valve mechanism, preventing leaks and ensuring a complete flush cycle.
3. Flush Mechanism:
- Flush Valve: The core component of the flushing system. Problems with the flush valve can result in incomplete flushing or leaks.
- Flush Lever/Button: The mechanism you use to initiate the flushing process. Replacement may be needed if it breaks or becomes faulty.
- Flush Valve Gasket/Seal: A crucial seal for the flush valve assembly, preventing water leakage.
4. Waste Tank and Related Parts:
- Waste Tank: This holds the wastewater until it can be emptied. Damage or leaks in this tank typically require a complete tank replacement.
- Waste Tank Level Sensor (if equipped): Indicates the level of waste in the tank. Replacement is needed if the sensor malfunctions.
- Vent Pipe & Accessories: Allows air to enter the tank, assisting with proper flushing. Blockages can be a cause of poor flushing.
5. Other Important Parts:
- Bolts and Nuts: Secure various components together. Replacement may be needed if they become damaged or corroded.
- Washer(s): Essential for sealing connections and preventing leaks throughout the system.
