WrekinWater SE2 Quartz Sleeve- Open Ended (QJ23580)

This open-ended quartz sleeve, part number QJ23580, is the correct replacement for WrekinWater's SE2 UV disinfection system, the larger sibling of the SE1. It fits over the UV lamp in the SE2 housing, keeping water off the lamp while letting UV-C light radiate through to treat the water passing around it. Order a new sleeve when the existing one is clouded, scaled or due its annual replacement.

Signs your quartz sleeve needs replacing

• Cloudiness, limescale or scratching visible on the glass
• Water starting to look, taste or smell slightly off
• The SE2's UV monitor flagging a low-dose warning
• Sleeve age approaching or past the 12-month mark

The SE2's quartz sleeve forms the barrier between the UV lamp and the higher volume of water the SE2 is built to treat, letting UV-C light pass through the glass while keeping the lamp itself completely dry. Scale and staining that build up on the glass over time reduce how much UV energy gets through, so the water can end up under-dosed even though the lamp is still lit. A new QJ23580 sleeve brings transmittance back to its original level.

WrekinWater is a family run company based in Bettisfield, Shropshire with UK Company No. 11000488, serving customers for 15 years and rated Excellent on Trustpilot. Because the SE2 is a WrekinWater system, this sleeve is manufactured specifically to match it rather than adapted from a generic size.

How to replace it

1. Isolate and drain the water supply to the SE2 housing
2. Remove the retaining nut or union to open the lamp chamber
3. Take out the UV lamp, then slide out the old sleeve
4. Clean the housing and fit fresh O-rings
5. Fit the new QJ23580 sleeve and reinsert the lamp
6. Restore water and power, then run the system to drain before use
