Jabsco Twist ‘n’ Lock Manual Marine Toilet, Wooden Seat, Self-Priming Pump

Overview

The Jabsco Twist 'n' Lock is a manual marine toilet range for powerboats and sailboats, available here with either a compact or regular bowl. It uses raw sea, river, lake, or canal water and connects to 19 mm inlet hose and 38 mm discharge hose, so it suits traditional manual head installations rather than pressurized freshwater systems.

The pump uses a 90 degree Twist 'n' Lock handle that locks the waste outlet valve shut after use, helping guard against siphonic flooding and waste backflow when the boat heels, pitches, or sits unattended. The toilet can be installed above or below the waterline when the full sanitation system is plumbed correctly with the required seacocks, vented loops, and hose clamps.

Key features

• Manual pump operation with no electrical wiring, breaker, or battery draw required.
• Twist 'n' Lock handle closes the waste outlet valve to reduce the risk of siphonic flooding and waste backflow.
• Self-priming flushing pump can prime from dry up to 1 m below the base, and the waste pump can discharge up to 3 m above the base.
• Fits 19 mm inlet hose and 38 mm discharge hose, common sizes for marine toilet plumbing.
• Reversible pump mounting lets the installer set the pump up for right-hand or left-hand operation.
• Multi-angle discharge elbow and fasteners facing the front or top help when fitting or servicing the toilet in a tight head compartment.
• White ceramic bowl with baked enamel wooden seat, plus a pump and base molded in ABS or polypropylene with 316 passivated stainless steel fastenings.

Variants

This Twist 'n' Lock manual toilet is offered in two bowl sizes. Both versions use the same manual pump concept, raw-water flushing arrangement, 19 mm inlet connection, 38 mm discharge connection, and lockable pump handle.

The main difference is the bowl footprint, which affects how the toilet fits in the head compartment and how much space remains around the seat, pump handle, and door swing.

• 29090-5000, Compact bowl: 330 mm high, 425 mm deep, and 455 mm wide, with a net weight of 9.5 kg. The smaller footprint is useful where head space, walkway clearance, or cabinet clearance is limited.
• 29120-5000, Regular bowl: 345 mm high, 485 mm deep, and 470 mm wide, with a net weight of 10.9 kg. The larger bowl size gives more seating room when the compartment has enough space around the toilet.

Installation and setup

Plan the installation around the toilet position, the vessel waterline, and the intended discharge route. Waste can discharge overboard where regulations allow, into a treatment system, or into an onboard holding tank.

Below-waterline installations need the correct vented loop arrangement in the inlet and outlet plumbing. Hose runs should use spiral reinforced smooth bore hose, and hose tails connected to through-hull fittings should be secured with stainless steel worm-drive clamps.

Materials and service access

The ceramic bowl is easy to wipe down, and the skirted base helps reduce dirt traps around the installation. The pump and base use molded plastic construction with selected acetal parts, brass weights, neoprene seals and gaskets, and 316 passivated stainless steel fastenings for service in fresh or salt water.

Service access is handled from the front or top, which matters on boats where the toilet is often tucked close to a bulkhead or vanity. The external seal housing allows the seal and piston rod guide to be replaced without taking the whole toilet apart.

Use on board

This toilet is a practical fit for sailboats, fishing boats, and cruising powerboats that need a simple manual head with familiar hose sizes and no electrical load. It is especially relevant for refits where the existing boat already uses a raw-water manual toilet layout with 19 mm intake and 38 mm discharge plumbing.

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.
