A UV purifier only works when its lamp is fresh, and most need a yearly swap. Here is the San Bruno guide.
The lamp
UV lamps weaken over time and stop killing germs, even though they still glow.
The schedule
Most manufacturers recommend replacing the lamp every 12 months.
The sleeve
The quartz sleeve also needs cleaning so the light reaches the water.
The call
