The installation of a Jabsco electric marine toilet requires careful attention to detail, encompassing plumbing, electrical connections, and a thorough understanding of the system’s components. These toilets, favored for their convenience and efficiency on boats, offer a significant upgrade over manual systems. This article provides a comprehensive guide to the installation process, key features, and considerations for choosing between different system configurations, based on available documentation.
Preparing for Installation
Prior to commencing installation, adequate preparation is crucial. This includes selecting a suitable location for the toilet, ensuring the area is clear of obstructions, and carefully reviewing the Jabsco toilet manual specific to the model being installed. It is recommended to turn off the boat’s water supply and disconnect any existing toilet systems before beginning. Measuring the distance between the toilet flange and the through-hull fitting is necessary to determine the appropriate length of PVC pipe required for connections. The installation process can vary in duration, averaging between 2-4 hours depending on the installer’s experience and the complexity of the specific installation.
Tools and Materials
A specific set of tools and materials is required for a successful installation. Essential tools include a drill, screwdriver, adjustable wrench, pliers, a hacksaw or PVC cutter, silicone sealant, and Teflon tape. Materials needed encompass the Jabsco marine toilet itself, a holding tank or direct discharge kit, hose clamps, flexible hose, mounting bolts or screws, a backflow preventer, and a through-hull fitting. Additionally, a multimeter is recommended for electrical checks, and seacocks are crucial for safety. Pump assembly parts, inlet hose, and discharge port fittings are also necessary components. The Jabsco marine kit typically includes many of these essentials.
Removing the Existing Toilet
The initial step involves removing the existing toilet. This begins with locating and removing the bolts securing the toilet to the floor, typically found near the base. Once the bolts are removed, the toilet can be carefully lifted straight up and removed from the base, potentially requiring assistance from another person. Following removal, the area around the toilet’s base should be thoroughly cleaned with a disinfectant cleaner.
Mounting the New Toilet
With the area prepared, the new Jabsco marine toilet can be mounted. The toilet should be placed on the mounting surface, and the locations of the mounting holes marked. Holes are then drilled, and the toilet secured with screws and bolts. Applying silicone sealant around the base of the toilet is recommended to prevent leaks. Ensuring the base of the toilet is stable is paramount for proper operation and longevity.
Connecting Plumbing
Connecting the inlet and outlet hoses is a critical step. Hoses must be attached to the toilet pump using appropriate fittings to ensure a tight seal. It is important to consider whether a raw water or fresh water supply will be used. Raw water is sourced directly from the sea, offering a free and abundant supply, but requires more maintenance. Fresh water utilizes potable water tanks, providing a cleaner flush but potentially consuming valuable freshwater resources. Each system requires its own vented loop setup. A backflow preventer should be installed to prevent contamination.
Electrical Connections
Jabsco electric marine toilets operate on 12v power. Wiring requires stripping wires and connecting them to a power source, utilizing a circuit breaker for safety. It is essential to ground the system properly. Connections should be made to the waterline fuse, and voltage drop should be checked to ensure optimal performance. The solenoid valve wiring should also be securely connected. Many models include a manual pump backup for emergency situations.
Key Components and Features
Jabsco electric marine toilets incorporate several key components. These toilets feature a self-priming flush pump and a macerator designed to handle waste effectively. Seacocks control water flow safely, and the “Quiet Flush E2” model is specifically engineered for silent operation. Pressurized water systems facilitate rapid bowl filling, and durable inlet and discharge hoses contribute to the system’s longevity. The joker valve is a vital component, acting as a seal to prevent reverse flow and ensure proper waste removal.
Manual vs. Electric Toilet Options
A comparison between manual and electric marine toilets highlights the advantages of electric systems. Manual toilets require physical pumping, which can be tiring, particularly on longer voyages. Electric toilets, conversely, utilize a button-activated flush, providing faster and easier operation. While manual toilets generally have a lower upfront cost, electric toilets save effort and are more convenient. Manual toilets are suitable for simpler setups, while electric toilets offer automated waste grinding and voltage drop protection.
Water Supply Considerations: Raw Water vs. Fresh Water
The choice between raw water and fresh water supplies impacts system maintenance and performance. Raw water, drawn directly from the sea, is readily available and cost-effective. However, it necessitates more frequent maintenance due to potential corrosion and biofouling. Fresh water, sourced from potable water tanks, provides a cleaner flush and prevents salt buildup, making it preferable for inland boating. Each option requires a properly installed vented loop to prevent siphoning and maintain pressure.
Safety Precautions
Prioritizing safety during installation is paramount. Boat owners should always wear gloves to protect their hands, turn off power to avoid electrical shocks, and check seacocks before handling hoses. Eye protection should be worn when drilling to prevent debris from causing injury. It is also recommended to disconnect the holding tank, ventilate the area adequately, and adhere to the guidelines provided with the Jabsco Quiet Flush model. Thorough testing of all connections and functions should be conducted after installation.
Troubleshooting and Maintenance
While the documentation does not detail specific troubleshooting steps, it does emphasize the importance of regular checks. The toilet may require periodic maintenance to ensure optimal performance. The joker valve, in particular, is a critical component that should be inspected regularly for wear or damage.
Frequently Asked Questions
The documentation addresses several frequently asked questions. Installation instructions are model-specific, so it is essential to use the correct manual for the particular Jabsco marine toilet. Specific plumbing and electrical components are recommended to ensure compatibility and proper operation. Specialized tools, including a hole saw, screwdriver, wrench, and drill, are required for installation.
Conclusion
Installing a Jabsco electric marine toilet involves a series of carefully executed steps, from preparation and removal of the old unit to mounting, plumbing, and electrical connections. Understanding the key components, features, and considerations for water supply selection is crucial for a successful installation. Adhering to safety precautions and consulting the specific model’s installation manual will ensure a reliable and efficient marine toilet system.
