3. Setup and Installation
Before beginning installation, ensure you have all necessary tools and that the toilet system is isolated from water supply and discharge. It is recommended to wear appropriate personal protective equipment.
- Preparation:
- Turn off the water supply to the toilet.
- Pump out any remaining water from the toilet bowl and pump assembly.
- Disconnect the inlet and outlet hoses from the pump.
- Disassembly:
- Carefully remove the pump assembly from the toilet base.
- Disassemble the pump, noting the position and orientation of all components, especially gaskets, O-rings, and valves. Refer to your specific toilet model's diagram if available.
- Remove all worn or damaged parts that are to be replaced by the service kit.
- Component Replacement:
- Clean all mating surfaces thoroughly before installing new parts.
- Install new gaskets and O-rings, ensuring they are properly seated and not twisted. A thin layer of silicone grease can aid in seating and sealing.
- Replace the old valves (e.g., joker valve, flapper valves) with the new ones from the kit, ensuring correct orientation.
- Install any new diaphragm or piston components as per the original assembly.
- Replace any worn screws or fasteners with the new ones provided.
- Reassembly:
- Reassemble the pump assembly, ensuring all screws are tightened securely but do not overtighten.
- Reattach the pump assembly to the toilet base.
- Reconnect the inlet and outlet hoses, ensuring hose clamps are secure.
- Testing:
- Turn on the water supply to the toilet.
- Operate the toilet pump several times, checking for any leaks at connections or within the pump assembly.
- Ensure proper flushing and discharge.
If you encounter difficulties, consult a qualified marine technician or refer to the original toilet manual for specific diagrams.
4. Operating Instructions (After Service Kit Installation)
Once the service kit components have been installed and tested, operate your manual toilet according to its original operating instructions. Proper operation ensures the longevity of the newly installed parts.
- Flushing: Pump the handle firmly and completely to ensure adequate water intake and waste discharge.
- Water Level: Ensure sufficient water is in the bowl before and after use to prevent odors and facilitate flushing.
- Winterization: If applicable, follow the manufacturer's winterization procedures to protect the pump and seals from freezing damage.
5. Maintenance
Regular maintenance helps extend the life of your manual toilet and the components from this service kit.
- Regular Cleaning: Use marine-safe toilet cleaners. Avoid harsh chemicals that can damage rubber seals and plastic components.
- Inspection: Periodically inspect hoses, connections, and the pump assembly for signs of wear, leaks, or corrosion.
- Lubrication: If recommended by the toilet manufacturer, apply marine-grade lubricant to moving parts of the pump.
- Freshwater Flushing: If using the toilet with saltwater, occasionally flush with freshwater to reduce salt buildup and corrosion.
