40mm DURSO AIR ADMITTANCE VALVE |
| Description: |
40mm Durso air admittance valve. This unit fits inside a 40mm plain socket such as the top of
the Durso tee section. By turning the black knob you allow air to be drawn into the Durso via a
slot running down the thread. Removing the screw by 50% will then allow increased air flow via a
further inlet. You will also require a tee, elbow and a length of pipe to make your Durso pipe.
Will reduce noise through your overflow system.
