The Jabsco 29015-0000 is a genuine Jabsco 3/4 inch vented loop for the flush water intake line on Jabsco marine toilets. Installed so the top of the loop sits well above the waterline, it lets air into the line and breaks the siphon that can otherwise draw seawater through the toilet and into the boat.
Siphoning is one of the most common causes of a flooded head compartment, especially on sailboats that heel or when the toilet is mounted near or below the waterline. A vented loop is inexpensive protection, and it should be kept clean so the vent valve can open freely.

Frequently Asked Questions
Q: How high should the vented loop be mounted?
Mount the top of the loop well above the waterline at all angles of heel, following the toilet installation instructions.
Q: Does the vent need maintenance?
Yes. Salt and scale can clog the vent. Clean it periodically so it can admit air and break the siphon.
Q: Can I use it on the discharge line?
This 3/4 in loop is for the intake line. The discharge line needs a loop sized to its larger hose.
Q: What happens if the vent sticks shut?
The loop stops protecting against siphoning, and water can flow into the toilet bowl when the boat is unattended.
