Jabsco Vented Loop 29015-0010 for 1.5 Inch Hose - Marine Toilet Waste Discharge Siphon Break

The Jabsco Vented Loop 29015-0010 is a vented loop fitting sized for 1.5 inch hose, built for the inlet and discharge plumbing of marine toilets. It is an essential safety component on any toilet installed below the static or heeled waterline, where a straight run of hose could allow water to siphon back into the boat. The vented loop uses a simple valve system that opens to break the siphon whenever the loop is not under positive pressure, ensuring that water cannot siphon over the pipe loop and flood the head or bilge.

This vented loop is moulded in tough plastic for corrosion resistance in the marine environment, an advantage over metal loop fittings that can corrode from constant exposure to seawater and waste discharge. It is intended for use in the waste discharge loop of the toilet system, positioned at the high point of the hose run above the waterline. Because it is sized specifically for 1.5 inch hose, it is intended as a direct fit into existing 1.5 inch marine toilet plumbing runs without needing to change hose diameter elsewhere in the system.

Why does a marine toilet need a vented loop? A vented loop is required on any toilet installed below the static or heeled waterline because it prevents water from siphoning back through the inlet or discharge hose.
