RQ-H151 - Atlas H151 Replacement Quartz Sleeve and Luminor RQ-950

WrekinWater supplies this replacement quartz sleeve for the larger Atlas H151 UV disinfection system, which is also sold as the Luminor RQ-950. The domed-end sleeve arrives complete with its O-ring, ready to swap in for a sleeve that has clouded, scaled or become discoloured with use.

Signs your quartz sleeve needs replacing

• Visible scaling, cloudiness or fine scratches along the sleeve.
• A brownish or yellow discolouration you can see through the glass.
• Water starts to taste or smell slightly off even though the lamp still lights.
• The UV monitor alarm sounds despite the lamp appearing to work normally.

The quartz sleeve on the H151/RQ-950 separates the UV lamp from the water flowing past it while allowing UV-C light to pass through and disinfect it. Limescale, iron staining or surface scratches on the quartz reduce how much of that light gets through, so the system can keep running with the lamp lit while disinfection quietly becomes less effective.

As a family run business based in Bettisfield, Shropshire with over 15 years and 50,000-plus customers behind it, WrekinWater stocks the correct part sizes for larger UV systems like the H151/RQ-950 so you're not guessing between similar-looking sleeves. Customers rate the service "Excellent" on Trustpilot.

How to replace it

1. Isolate the water supply to the UV housing and switch off the unit.
2. Drain the chamber, then undo the retaining nut or union cap at the base.
3. Withdraw the UV lamp first, then carefully slide out the old quartz sleeve.
4. Clean the inside of the housing and fit the new O-ring before inserting the new sleeve.
5. Refit the lamp, reassemble the union or retaining nut, and restore power and water.
6. Run the system to drain briefly before using the water again.
