What a Wax Pan Seal Does
A wax pan seal forms a compressive seal between the toilet pan outlet and the waste pipe flange. When the toilet is installed, the wax compresses and adapts to minor surface irregularities, helping to create a watertight and gas-limiting barrier.
This supports:
-
Reduced risk of water leaks around the toilet base
-
Limitation of sewer odours entering the bathroom
-
Stability of the toilet installation over time
Performance depends on correct installation, compatibility, and site conditions.
