WakeMAKERS Vented Loop Anti-Siphon Valve

Vented loops prevent passive filling and draining that can occur when using aerator style pumps.

Prevent passive filling and draining of your ballast bags with this affordable and easy to install fitting.

This fitting installs in the fill line running from the pump to the bag to prevent venturi draining and forced filling of the bag. Installation is easy, simply cut the fill hose and install the vented loop onto the exposed ends. For proper operation, the loop should be installed as high in the boat as possible, and as close to the ballast tank or bag as possible (minimizing the length of hose from the vented loop to the ballast reservoir).
