MCALPINE VALVE VENTAPIPE 15 VP15M

The McAlpine Ventapipe 15 (VP15M) is an air admittance valve designed to balance pressure in domestic waste and soil systems. It automatically opens to allow air into the pipework during discharge and closes to prevent foul odours from escaping when the system is at rest.

Suitable for internal use, it is intended for vertical installation above the flood level of connected fixtures. This helps maintain water trap seals, reduces gurgling, and can remove the need for additional roof penetrations in many installations.
