We recommend replacing gaskets whenever you install a new bulb
Gaskets loose elasticity and are unable to make a proper seal after approximately 3 months in a chlorine pool
Chlorine in pool water degrades the gasket over time but silicon based gaskets resist degradation much better than rubber based gaskets
Typical lifetime of this gasket is 5-10 years if not opened and sealed correctly
