Keep your water safe, clean, and free from harmful microorganisms with our complete range of UV replacement parts. At Wrekin Water Treatment, we stock genuine UV bulbs, quartz sleeves, seal kits, and control boxes for leading brands such as Wrekin SSi, Sita, Atlas, Wonder, Silverline, and Daro.

Whether you’re maintaining a domestic or commercial UV disinfection system, our replacement parts ensure reliable performance, consistent sterilisation, and long service life.

Replace Your UV Lamp Annually for Maximum Protection

To maintain effective UV disinfection, it’s essential to replace your UV lamp every 12 months. Over time, UV output decreases—even if the bulb still lights—reducing its ability to kill bacteria and viruses.

We supply replacement UV bulbs for a wide range of systems, including GPH-series lamps (GPH620, GPH843, GPH880, GPH1148, etc.), Philips TUV lamps, and high-output (HO) UV lamps. Each bulb delivers optimal ultraviolet intensity to ensure safe, microbiologically clean water.

You can simple re-order your bulbs by logging into your account and seeing your previous orders.

Quartz Sleeves

Your quartz sleeve acts as a protective barrier between the UV lamp and water flow, keeping the lamp dry while allowing maximum light transmission. Over time, scale or staining can reduce UV efficiency—regular cleaning or replacement ensures consistent protection.

We also stock seal kits, O-rings, and power supply units (PSUs) compatible with Atlas, Sita, and Wrekin SSi UV systems, helping you perform complete maintenance without guesswork.
