UV quartz sleeves: all you need to know

The quartz sleeve is the clear glass tube that houses the lamp inside your UV water filter. It keeps the lamp dry and away from the water, while letting the UV light shine through evenly to disinfect every drop.

When the sleeve gets dirty, cloudy or cracked, less UV light reaches the water and bacteria can get through, even though the lamp still looks like it’s working. That’s why we check and clean the sleeve at every UV service.

Cleaning and replacement, done properly

We clean your sleeve, replace it if it’s damaged, and then sterilise the UV chamber and the water lines into your home, so you can trust the water from every tap.

Cleaning, replacing and checking your quartz sleeve
What we do, and what to look out for

Cleaning UV quartz sleeves

Most UV manufacturers recommend cleaning the quartz sleeve every 6 to 12 months to keep UV transmission high. We recommend:

  • Domestic UV systems: clean every 12 months
  • Commercial UV systems: clean every 6 months

Our cleaning policy: a dirty sleeve reduces UV light and can make your water non-potable. If a sleeve can’t be cleaned, we replace it. If it’s getting unusually dirty, we’ll find out why and may suggest more frequent cleaning.

Replacing UV quartz sleeves

Manufacturers typically recommend replacing the sleeve every 12 to 18 months, or sooner if it becomes brittle, cracked or cloudy. With careful handling, some sleeves last 7 to 10 years.

Our replacement policy for onsite service customers:

  • We replace sleeves when they break, crack or become cloudy
  • If a sleeve breaks because it’s brittle, the replacement cost is passed on to you
  • If we break it by accident, we cover the cost
  • Call us on 0800 278 296 for the current price of a replacement sleeve

Signs of a brittle quartz sleeve

UV light, heat, chemicals in the water and knocks during handling all weaken the glass over time. Look out for:

  • Cracks or brittleness
  • Cloudiness or discolouration
  • Water leaking around the seals
  • Reduced UV light output

If you notice any of these, call us.

Thinking about doing it yourself?

Skills you’ll need

Cleaning or replacing a quartz sleeve takes electrical and plumbing skills. UV systems run at high voltage, the water lines must be disconnected and reconnected, and you’ll need the right tools, plus a spare sleeve in case the old one breaks. Without a working sleeve, your drinking water isn’t protected.

Watch out!

The glass sleeve breaks easily, and it is far more likely to break in untrained hands. If it does, you must remove every piece of glass from the water system. Glass left behind can be life-threatening if it ends up in your drinking water.

Sterilise afterwards

After any work on the sleeve, the UV chamber and water lines must be sterilised before you drink the water again. Every Aqua Works service includes this step, following the manufacturer’s recommendations.

UV Quartz Sleeve FAQs

What is a UV quartz sleeve?

A UV quartz sleeve is the clear glass tube that houses the UV lamp inside the chamber of your UV system. It keeps the lamp dry and away from the water, while letting the UV light pass through to disinfect the water.

Why are UV quartz sleeves so important?

The sleeve protects the lamp and spreads the UV light evenly through the water. If the sleeve is dirty, cloudy or cracked, less UV light reaches the water and bacteria can get through.

How often should a quartz sleeve be cleaned?

Most manufacturers recommend every 6 to 12 months. We clean domestic sleeves every 12 months as part of your annual UV service, and commercial systems every 6 months.

How often should a quartz sleeve be replaced?

Manufacturers typically recommend every 12 to 18 months, or sooner if the sleeve is brittle, cracked or cloudy. With careful handling some sleeves last 7 to 10 years, so we check yours at every service and replace it when it needs it.

What makes a quartz sleeve brittle?

UV light, heat, chemicals in the water and knocks during handling all weaken the glass over time.

What are the signs it's time to replace my quartz sleeve?

Cracks, brittleness, cloudiness or discolouration, water leaking around the seals, or reduced UV light output.

Can I clean or replace a quartz sleeve myself?

It is possible, but it needs electrical and plumbing skills. UV systems run at high voltage, the water lines must be disconnected and reconnected, and the glass breaks easily. If a sleeve breaks, every piece of glass must be removed from the water system, and the UV chamber and water lines must be sterilised before you drink the water again.

Why use a professional for quartz sleeve servicing?

Safety, expertise and efficiency. We carry around 30 sleeves so we have the right one on hand, we sterilise the UV chamber and water lines afterwards, and our work is backed by the Aqua Works guarantee. Call us to book a service.
