Twist’n’Lock manual large bowl

The Twist’n’Lock function is a safety mechanism integrated into the pump handle. It locks the piston with a quarter turn, preventing backflow of wastewater and siphoning, thus ensuring better hygiene and safety on board.

This Jabsco marine toilet model is fitted with a large bowl, providing increased comfort for the user.

This marine toilet is a manual model. It uses a piston pump for flushing water intake and waste discharge.

Yes, Jabsco marine toilets are generally supplied with a seat and lid. While the specific material is not detailed for this exact model, it is designed as a complete sanitary solution.

Yes, this marine toilet can be used with seawater, river water, or lake water for flushing. It is designed for versatile use on all types of waterways.

Benefits of a manual marine toilet include:

Reliability: Fewer electrical components, so fewer failure risks. Autonomy: Operates without electricity, ideal for boats without batteries or in case of power failure. Ease of use: The manual mechanism is simple to understand and operate. Cost: Generally more economical to purchase and maintain than electric models.

The manufacturer part number (MPN) for this Jabsco Twist’n’Lock manual marine toilet with a large bowl is 29120-5000.

Yes, as a marine toilet from the Jabsco brand, it is built with materials resistant to marine environments, including corrosion from seawater, to ensure durability.

This toilet is equipped with a manual piston pump. This mechanism efficiently draws in flushing water and pumps out wastewater.

Yes, the pump’s installation is reversible, providing flexibility to adapt to different onboard space configurations.

The diameters of the fittings are as follows:

Seawater intake: Ø19mm (3/4'') Black water discharge: Ø38mm (1 1/2'')

Yes, the pump can be installed in either orientation. This means you can position it according to your installation requirements, providing great flexibility.

Yes, this Jabsco marine toilet can be installed either above or below the waterline of your vessel, offering versatile installation options.

Yes, this marine toilet is designed to pump waste directly overboard or into a holding tank, depending on your system configuration and applicable regulations.

Although the Twist’n’Lock mechanism includes a backflow prevention function, adding a non-return valve at the suction side (reference 29295-1011 or similar) can improve flushing response and prevent loss of priming, especially in installations above the waterline. This is a recommended accessory to optimize performance.

For a complete and optimized installation, the following accessories are recommended:

Y-valve: To divert wastewater to a holding tank or overboard (part number 45490-1000).Vented loops: To prevent siphoning in installations below the waterline (part numbers 29015-0000, 29015-0010, 29015-0020).Pump filter (Toilet Pumpgard): To protect the pump from debris.Check valve: To improve priming and flushing (part numbers 29295-1011, 29295-1000, 29295-1010).

The piston is locked by turning the pump handle a quarter turn. This action activates the "Twist’n’Lock" mechanism, securing the piston in position and preventing backflow and wastewater siphoning.

This manual head uses an external water supply for flushing, drawing directly from the sea, a river, or a lake. It does not include an internal flushing mechanism, meaning there are no voltage or pump type specifications for an integrated flushing system.

Yes, Jabsco offers conversion kits for marine heads that allow you to upgrade an existing manual head to an electric version. This lets you modernize your head’s functionality without replacing the entire unit.

For wastewater discharge, a Y-valve (such as part number 45490-1000) is commonly used. It allows directing wastewater flow either directly overboard or into a holding tank, depending on requirements and regulations.
