McAlpine Ventapipe Auto Air Vent - VP4

The Ventapipe is an air admittance valve that allows air into a drainage system to prevent siphoning and maintain proper pressure, preventing sewer gases from entering a building.

The VP4 should be installed vertically, above the flood level of the highest fixture in the system.

The VP4 is compatible with copper, plastic, and lead pipes.

Periodically inspect the valve for blockages or debris and clean as needed.

This indicates the rate at which the valve can allow air into the system, which is crucial for effective venting. The VP4 has an air flow capacity of 2 liters per second.

While the VP4 is suitable for many systems, it's essential to consider the size and configuration of your system. Larger systems might require a higher capacity valve. Always consult local plumbing codes and regulations.

If the VP4 fails, the drainage system may experience slow draining, gurgling sounds, or the release of sewer gases into the building.

The Multifit Tee is a fitting included with the VP4 that allows it to be easily connected to different types of pipes.

Check the valve for proper installation and ensure a good seal. Inspect the trap seals in fixtures and check for any leaks in the system.

Check the valve for blockage or debris. Ensure the air vent is clear and functioning correctly.

Indicates insufficient venting. Verify the VP4 is correctly installed and that the airflow capacity is sufficient for the system.
