UV & pump parts

What to replace, and when

Know what you're working on, a UV system or a pump, and match the brand and model where it matters.

• Change the UV lamp once a year

  UV output drops over time, so lamps are changed on a schedule rather than when they stop glowing: once a year, even if it still glows. Match the wattage, length and pin type, or the code on your old lamp. Turn the power off first and follow your system's instructions.

• Clean or replace the quartz sleeve

  The quartz sleeve is the glass tube that protects the lamp and keeps it dry inside the chamber. Clean it at each lamp change, and replace it if it's scratched, cloudy or cracked. Replace the O-rings at the same time.

• Ballasts, O-rings and other UV spares

  Lamp not lighting? A faulty ballast could be the cause, so check the ballast suits your system before you order. Springs, nuts and O-rings hold the sleeve in place and seal the chamber. Tell us the make and model of your UV unit and we'll point you to the right part.

• Controllers, tanks and covers for pumps

  A controller switches your pump on when a tap opens and off when it closes, and protects it if the water runs out. A pressure tank holds water under pressure, so the pump doesn't start every time a tap opens. If your pump is outside, a cover keeps the sun and rain off while letting air move around it. Tell us your pump model and we'll match the part.
