Tank-Above-Waterline-Layouts

Product catalog summary

Overview: This document provides guidelines and diagrams for various marine sanitation holding tank layouts, specifically for tanks positioned above the waterline. It includes different configurations of gravity discharge and manual pump systems, each with specific components like charcoal vents, deck pumpouts, diverter valves, and ball valves.

Specifications: The document outlines the use of 1 ½” sanitation hoses for all pipework, including vents, and recommends a 2” outlet hose for gravity discharge systems. It advises on the use of double clamping for connections below the waterline and suggests anti-syphon loops be at least 10” above the waterline.

Procedures: The document suggests that seacocks should be closed while waste is in the tank and opened only during discharge. It also notes that electric pumps can be used in place of manual pumps, but they will not completely stop waste discharge.

Recommendations: For optimal performance, changing the seacock to 2” is recommended if the boat is out of the water. The document also recommends the Gobius 4 non-invasive system for waste level indication due to its maintenance-free design and lack of leak potential.

Components and Accessories: A detailed list of components is provided, including shell vents, deck pumpout fittings, microvents, anti-syphon loops, diverter valves, sea cocks, Y pieces, manual diaphragm pumps, electric macerators, and more. The document also refers to an online catalogue for additional accessories.

Diagrams and Layouts: The document includes multiple layout diagrams, each illustrating different configurations of holding tank systems. These diagrams serve as guidelines and starting points for installation, with a note that not all components may be present in each layout.

Marine Sanitation Holding Tank Layouts The following pages show various diagrams for tanks positioned above the waterline. They are purely representations of possible layouts and should be treated as guidelines only. There are many more combinations of fittings and pumps etc but you should however find them a useful starting point. We are always on the end of the phone and would be pleased to discuss any variations you can think of! The gravity discharge systems work well with 2” outlet hose but this is not always possible because existing seacocks are normally 1 ½”. Changing seacocks is not...
