Overview

The Jabsco 37068-2000 is a vented loop solenoid valve for 37010 Series electric toilets. It is used on the inlet side when a vented loop is fitted, so the toilet can keep its prime and flush properly. This matters most on boats where the toilet sits below the waterline and the intake line needs a vented loop to prevent siphoning.

This valve connects to the vented loop air fitting and uses a 1/4 inch BSP brass connector. It can be used on 12V or 24V DC systems and is wired in parallel with the toilet motor, with one side going to the flush switch and the other to battery ground.

For a buyer checking fit, this is not a general plumbing solenoid. It is a dedicated toilet-system accessory for the inlet pipework of the 37010 electric toilet, so it makes sense when that specific toilet and vented loop arrangement are already part of the installation.

Key features

• Made for Jabsco 37010 Series electric toilet inlet pipework
• Used with a vented loop to help the toilet keep prime during the flush cycle
• 12V or 24V DC operation for common marine electrical systems
• 1/4 inch BSP brass connector screws onto the vented loop fitting
• Wires in parallel with the toilet motor through the flush switch and battery ground
• Intended for short-duty operation and should not be run continuously for more than 30 seconds

Compatibility and fit

This valve is for the 37010 Series electric toilet and fits the inlet side of that system. It is used when the intake hose includes a vented loop, which is common on installations where the toilet may sit below the waterline at rest or when the boat heels or trims underway.

The connection point is the vented loop air inlet. The brass connector threads onto the loop, and PTFE tape is used at that joint to seal it. If you are matching parts for an existing toilet setup, the key checkpoints are 37010 Series toilet compatibility, a vented loop in the inlet hose, and a 12V or 24V DC toilet circuit.

Installation and setup

On installation, the valve mounts at the top of the vented loop after the cap and rubber duckbill valve are removed. The air inlet on the loop then works through the solenoid during the flush cycle instead of staying open all the time.

Electrical hookup is straightforward for anyone already working on a marine toilet circuit. The solenoid is connected in parallel with the toilet motor, so it opens and closes with the flush command rather than needing a separate switch. This suits owners replacing a failed valve or adding the correct priming setup to a 37010 toilet installation.
