Vented Loop - Suits 38mm - 1 1/2" Hose (139096)
Prevents Seawater Siphoning Back When Installation is Below or Near Sea Level
Installed in toilet systems where the toilet or holding tank is below waterline or near waterline, to prevent sea water from siphoning through the toilet system, potentially swamping the vessel. Inlet and outlet plumbing is looped well above waterline and the vented loop is installed at the top of the loop, preventing siphoning. When installing ensure the vented loop will remain above water line when boat is fully loaded and / or heeled.
