Vented Loop 19mm BLA

The Vented Loop 19mm BLA is a crucial component for marine plumbing systems, specifically designed to prevent siphoning and backflow of seawater into your boat's toilet or holding tank. This vented loop is ideal for installations where the toilet or holding tank is located below or near the waterline. Its innovative design ensures reliable performance while maintaining proper ventilation, making it an essential accessory for any marine vessel.

--

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.
