Yes, the VP3 valve is maintenance-free and does not require periodic cleaning or servicing.
Yes, the compact design of the VP3 allows it to be installed in tight spaces where traditional vent pipes may not fit.
The VP3 has an airflow capacity of 4.5 l/s.
Air admittance valves like the VP3 prevent trap seal siphoning, eliminate negative pressure, and are easy to install, making them a practical and efficient solution for venting waste pipes.
The VP3 valve should be installed in a location that is easily accessible for inspection, typically connected to the waste pipe.
This often indicates a lack of venting. Ensure the VP3 valve is properly installed and that the seal is secure.
Check for any blockages in the waste pipes or the VP3 valve itself. Ensure that the valve is correctly installed and not obstructed.
Inspect the traps to ensure they are filled with water. If the traps are siphoning, the VP3 valve may not be functioning correctly or there may be other issues with venting.
