Maintenance of Your UV System

Maintenance of Your UV System

Maintenance of Your UV System, A UV purification system uses UV-C radiation to kill harmful bacteria and is a highly effective water treatment technique. Cysts, pathogens, and microbiologically dangerous organisms like Giardia and Salmonella are rendered harmless by UV radiation.

However, UV purifiers do require annual maintenance to run efficiently and safeguard their performance, just like all water treatment systems. The best way to make sure your UV system is protecting you from bacteria and disease is to take good care of it, which includes cleaning your quartz sleeve and changing your UV lamp once a year.

How frequently should I replace my UV lamp?

UV lamps should be replaced every 12 months. A UV lamp’s lifespan is roughly 9,000 hours. According to calculations, the lamp can be used for approximately 375 days before needing to be replaced.

Technically speaking, the lamp lasts for about a year and a week, giving you some leeway in case you forget to order a replacement lamp in time. But it’s a good idea to always have a spare lamp on hand, or to set a reminder to place an order for a new one a month before the old one runs out.

Disinfection will stop after 9,000 hours, and you won’t be shielded from any water contaminants that are microbiologically dangerous. After the UV lamp burns out, all that remains is for water to be passed through a glass tube inside a pipe.

It’s crucial to replace the UV system’s o-rings every time you replace your UV lamp. O-rings guarantee a watertight and leak-free seal. However, they will deteriorate and lose strength over time. When you replace your lamp, make sure to install fresh o-rings to prevent water from leaking out and harming any of the electrical parts of the system.

Why should UV lamps be replaced?

Mercury is the source of UV lamps’ germicidal abilities. Each glass UV lamp has mercury beads inside that produce electrical arcs that clean the water. The mercury in the lamp produces UV-C light when heated.

This UV radiation generates wavelengths that are germicidal and capable of killing bacteria. Bacteria cannot grow when they are exposed to UV-C rays. The microorganisms in the water are rendered inactive by the UV lamp’s mercury-fueled ultraviolet light.

The mercury will gradually deplete as heat is applied to it for the 9,000 hours that the UV lamps are in operation. The mercury’s effectiveness has worn off after 9,000 hours, and the light emitted from the lamp will no longer irradiate any aquatic microorganisms.

UV lamps only contain trace amounts of mercury, which is risky at high concentrations. The mercury does not pose any health risks and is never directly exposed to the water. Although mercury can also have a negative impact on the environment, UV lamps can be disposed of safely.

UV lamps can actually be recycled, just like fluorescent light bulbs. The mercury can then be recovered and used again for other purposes. In fact, a number of states mandate that all burned-out UV bulbs be recycled. Ask your neighborhood hardware store if they have a place where you can recycle used light bulbs. If not, the majority of manufacturers provide mail-back kits that include shipping.

What happens if I restart the alarm for the UV system?

When the UV lamp stops producing germicidal rays and the water is no longer being disinfected, the alarm that most UV systems have will sound. This practical feature can assist in reminding system owners when it’s time to swap out burned-out bulbs.

However, some people will turn off the alarm on the ballast to stop it from beeping, much like the indicator light on the refrigerator instructs you to change the batteries.

However, this is a bad idea for two reasons, unless you’ve actually replaced the UV lamp with a replacement bulb. The lamp’s intensity will, first and foremost, continue to deteriorate. Long before the alarm sounds 365 days later, it will continue to lose effectiveness until it is completely useless.

In addition, the UV system’s ballast will work harder and harder to try and maintain the ultraviolet wavelength’s intensity if the UV lamp isn’t replaced. The system overworks itself in an effort to produce the same UV dosage without the help of mercury. The system is overworked as a result.

Anytime a system exerts effort to fulfill its intended purpose, there is a chance of damage and an early decline in overall performance. Therefore, it’s imperative that you change your lamp when the lamp replacement alarm is triggered for both your safety and the protection of the UV system.

Can I turn off my UV system when it is not in use?

Whether you are passing water through your UV system or not, you should keep it on. First off, you run the risk of contaminating your home if you forget to turn the system back on. Second, repeatedly turning on and off the UV system actually reduces the lamp’s lifespan.

The energy required to restart the system will deplete the lamp’s 9,000-hour lifespan. You might only get 10 months of disinfection out of the lamp rather than a full year if you frequently turn the system on and off.

If you have a seasonal residence, such as a cabin or lodge, that uses a UV system to disinfect its water, that is the only situation in which it would make sense to occasionally turn off your UV system. You can turn the lamp off when you leave if you only intend to stay in this house for a few months of the year.

To replace the lamp, you will need to carefully plan when to do so and be vigilant about keeping track of how many months you are spending at the house. Replace the UV lamp at least twice every two years, even if you only use the space for a few months of the year.

It is not worth risking exposure to pathogens that are microbiologically dangerous in your water in order to prolong the UV lamp’s life by a few months.

How to change a UV lamp

  1. Cut the water off. Find your water main and shut off the water supply to the entire house. Ensure that no water-using appliances are in use and that all of your home’s faucets are closed.
  2. Set the UV system apart. Disconnect any power sources feeding the UV system. Wait until the system has cooled down if it is still warm.
  3. Remove the lamp plug and unscrew the safety cap. When handling the lamp, use a cloth or protective gloves. Your skin’s oils will compromise the durability of the quartz lamp and sleeve.
  4. Take out the sleeve and UV lamp from the chamber. Remove the sleeve bolt, then throw away the old o-rings. When you install the new lamp, you will be swapping these out for new o-rings. Remove the old lamp with care from the quartz sleeve.
  5. Get the quartz sleeve clean. Clean the quartz sleeve of any stains or discolorations using a cloth dipped in CLR. Be cautious because quartz sleeves are very brittle and are prone to breaking. You should also use this opportunity to install a new sleeve if you haven’t changed yours in a while.
  6. O-rings on the sleeve should be changed.
  7. Place a fresh UV lamp inside the assembly. Avoid overtightening the lamp, as it could cause cracking.
  8. Place the new lamp and sleeve inside the apparatus. Before replacing the safety cap, make sure the lamp is properly positioned in relation to the lamp plug.
  9. Restart the water supply and look for leaks. Run water through the system to ensure that it is functioning properly and that there are no leaks. Always check your manufacturer’s instructions for regular cleaning and maintenance instructions.

Remember that different UV systems will have various configurations. To remove the sleeve and lamp for replacement, you might need to take different actions. However, you should always use the opportunity to clean the quartz sleeve and replace the o-rings whenever you are changing your UV lamp.

Why are quartz sleeves used in UV systems?

The quartz sleeve is a transparent glass tube that enables the water to be cleaned by germicidal UV waves passing through the glass. Quartz sleeves are made specifically to pass through UV-C rays and be transparent to UV light.

Regular glass is not transparent, so UV light cannot pass through it to kill bacteria and other living things in the water.

The quartz sleeve also performs the crucial task of separating electricity from the water stream. It should go without saying that electricity and water do not mix in the water. It goes without saying that electricity and water don’t mix. The quartz sleeve makes sure that the UV lamp or any other electrical part of the UV purification system never comes into direct contact with water.

Why should I wash my quartz sleeve?

The UV-C radiation cannot sanitize the water if the quartz sleeve is not clear and spotless. If the glass is cloudy or dirty, UV-C light cannot pass through it. Similar to how bacteria and other organisms can conceal themselves behind sediment, they can evade the disinfection procedure if the glass is too cloudy for the UV light to penetrate.

The calcium and magnesium minerals in hard water can deposit scale on the sleeve. The transparency of the sleeve will be masked by these scale formations. The sleeve may become too muddy for the UV-C light to pass through if your water is contaminated with high levels of iron or manganese, two water contaminants known for their bright orange stains.

Even if your water is fairly clear and untinted, the sleeve will eventually become dirty from contact with water over time.

This emphasizes how important proper pre-treatment is before using your UV system. A 5-micron prefilter is essential to the effectiveness of any UV system because pathogens and bacteria can conceal themselves behind particulate matter and sneak through the system undetected (this is known as “shadowing”).

This will get rid of any flakes or other debris that might cover the aquatic life in your water. In addition, if your water is hard, installing an ion exchange water softener will safeguard your UV system as well as other home appliances like water heaters, showerheads, and dishwashers. The harm that hard water causes to a house is well known.

By installing a water softener before your UV system, you can prevent scale from adhering to your quartz sleeves and avoid having to replace them frequently. By removing the iron from your water, you can extend the life of your quartz sleeve and get rid of unsightly muddy orange stains from your house.

Learn more about how water softeners function and how to remove iron from well water.

How should my quartz sleeve be cleaned?

Use a cloth dampened in CLR or another mildly acidic cleaning solution, such as vinegar, to gently wash the sleeve. This will clear the sleeve of any limescale accumulation as well as any stains, cloudiness, or discolorations.

Always wear protective gloves because the oils on your hands and skin can mar the transparency of the glass and the quartz sleeves. Never clean the lamp with a rough hand towel or washcloth.

When polishing glass, if the cloth is too coarse, it will scratch and scrape the surface. Additionally, take care not to damage the sleeve. The sleeve is extremely brittle, and any kind of chip or crack will render it useless.

How often should I get a new quartz sleeve?

The quartz sleeve in your UV system needs to be changed every two to three years. The quartz sleeve will no longer be sufficiently restored to its transparent state after two to three years of cleaning.

Water passing through the quartz sleeve will be sufficiently disinfected if the sleeve is routinely replaced. You might need to swap out the sleeve more frequently depending on your water supply.

A spare quartz sleeve should always be kept on hand as well. Quartz glass is incredibly strong, but it is also very fragile.

The sleeve can be completely cracked, chipped, or broken with very little force. You won’t be able to run any water through your house until you buy a new sleeve if you break yours while changing your lamp. Therefore, it is always advisable to have a backup quartz sleeve available as insurance in case the one that is in use is damaged.
