FAQs
What is the purpose of an air admittance valve?

Where should the McAlpine VP2 be installed?
The VP2 should be installed vertically on the waste pipe, typically near the fixture it serves.
Is the VP2 suitable for all types of plumbing systems?
The VP2 is suitable for many standard plumbing systems. Always check local plumbing codes for compliance and when in doubt, consult with a professional.
How do I know if my VP2 is working correctly?
If your drains flow freely and there are no foul odors, your VP2 is likely functioning properly. Regular inspection is recommended.
Can I replace a vent stack with a VP2?
The VP2 is an alternative for smaller systems, but may not fully replace a vent stack in larger or more complex plumbing setups. It is usually best to consult a professional.
How long does the McAlpine VP2 typically last?
With proper installation and care, the McAlpine VP2 can last for many years. However, periodic inspection is always recommended.
How do I clean the McAlpine VP2?

Troubleshooting
Drains are still slow or gurgling after installation.
Check for any blockage in the waste pipe or the valve itself. Ensure the valve is installed correctly and that the seal is airtight. If problems persist, consult a professional plumber.
Odors are still present.
Verify the valve is properly sealed and installed correctly. Inspect for any leaks in the waste system. Consider whether the issue is originating from another source.
The valve is leaking.
Check the connections for tightness. Replace the valve if it is cracked or damaged. Ensure the valve is appropriate for the system's needs.
The valve is making a whistling noise.
This may indicate a problem with the vent's seal, improper installation, or an obstruction. Inspect the valve and its connections for any leaks and ensure it's not blocked.
