Jabsco 3/4-Inch Vented Loop Toilet Anti-Siphon Valve

This Jabsco Vented Loop is an anti-siphon safety device built for use with both manual and electric marine toilets installed below the waterline. It works whether the boat is sitting static or heeled over under sail.

Without a vented loop in the line, a toilet plumbed below the waterline can siphon water back into the bowl and eventually into the boat. That's a genuinely serious flooding risk that's easy to overlook until it happens.

This 3/4-inch size matches the standard hose diameter most marine toilet installations already use. It's a straightforward part to add to an existing below-waterline installation. Explore more toilet parts and accessories.
