These valves allow proper venting to occur within certain sections of your plumbing system. It is a one-way mechanical valve, specifically designed to prevent gasses and odours from remaining around your toilet or bathroom. They keep the fumes in your tank or drain plumbing, so long as there is adequate water in another component know as the P-Trap.

While there are a number of these valves on the market – with slight physical or visual differences between each other – the most important factor behind choosing the correct valve for your system is getting the right size. These valves play a crucial role in your plumbing system and installing them can be complex. For this reason, we recommend hiring an expert, who will help to ensure your valve is installed securely and reliably.
