Jabsco Twist 'n' Lock Manual Marine Toilet, Regular Bowl, Soft Close Lid

Overview

The Jabsco 29120-5100 is a manual raw-water marine toilet with a regular bowl, a soft-close composite seat and lid, a 19 mm inlet, and a 38 mm discharge. It uses the Twist 'n' Lock handle to shut the waste outlet valve with a 90 degree turn, which helps stop siphoning and waste backflow when the toilet is not in use.

This model can be installed above or below the waterline, the pump can be moved to the right or left side during installation, and the discharge can run overboard or to a holding tank. The regular bowl format gives more room than a compact head, and the overall size is about 470 mm wide, 485 mm deep, and 345 mm high.

The bowl is ceramic, while the pump and base use corrosion-resistant molded parts with service components such as 316 stainless fastenings, neoprene seals, and gaskets. It is built for sea, river, or lake water and should not be connected to a pressurized freshwater system.

Key features

• Twist 'n' Lock handle closes the waste outlet valve with a 90 degree turn to help reduce siphoning and waste backflow
• Self-priming double-acting piston pump can draw flush water from up to 1 m below the base and discharge waste up to 3 m above it
• Reversible pump mounting lets the installer place the pump on the right or left side
• 19 mm inlet and 38 mm discharge match common marine sanitation hose sizes
• Constant 38 mm waste path and a multi-angle discharge elbow help with hose routing and reduce blockage points
• Regular bowl with soft-close composite seat and lid for a more familiar onboard fit than a compact bowl

Installation and setup

This toilet is supplied assembled for right-hand operation, but it can be reassembled for left-hand use before mounting. The discharge elbow can be rotated to suit hose routing, which helps when space behind the head is limited.

For below-waterline installations, the plumbing layout matters as much as the toilet itself. Full-bore seacocks, secure hose clamping, and vented loops in the correct places are part of a safe installation, especially on boats that heel or run in changing trim.

Compatibility and fit

This model suits boats already set up for a manual raw-water head and is compatible with systems that discharge overboard where allowed, or into an onboard holding tank or treatment system. The regular bowl makes sense where crew comfort matters and there is room for a full-size manual head rather than a compact unit.

It is a practical choice for cruising sailboats, powerboats, and fishing boats that want a manual toilet with no electrical draw and parts that are easy to reach for routine service. Buyers replacing another 29120-series regular bowl installation should still confirm hose routing, mounting clearance, and pump-side preference before ordering.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
