[VIDEO] Water Tank UV - How to Set Up Your Whole House Rain Water Tank Filter System with UV Light

A UV light water filter is a brilliant way to turn rainwater into magnificent drinking water. In this article, you will discover how simple it is to set up your Whole House Rain Water Tank Water Filter to work with a UV light.

A UV light sterilisation water filter is a fantastic way to treat your water without contaminating it with chlorine and other poisons. Using a UV light, water treatment is a healthy way to guarantee your water quality is suitable to consume.

These ultraviolet steriliser systems are not really for scheme water but for untreated water to kill unwanted parasites, viruses and bacteria that cause ill health or even death.

General Notes

As you will see in the video below, we are working with a Twin Whole House Rain Water Filter.

There is a Sediment pleated cartridge in position one and a carbon cartridge in position two.

Once we’ve connected up the UV light, we run the water through and test for leaks first, BEFORE applying any electricity. 

We highly recommend installing an on/off tap at either side of your water filter so that the system can be isolated for cartridge changes, bulb changes and cleaning. It’s beneficial to be able to do this without having to turn your mains water off.

Anytime you need to work on the system or need to change the globe in your UV light (which should be every 12 months), you can simply switch the water off right there at the filter.

UV Light Mounting Position

If you decide to mount the UV light horizontally, you need at least an extra 90cm clearance to change the bulbs, sleeves, etc.

If you install the UV light vertically, just ensure you’re extra careful never to drop the globes in, but instead, slide them in slowly and carefully from the top.

When you are mounting the UV light, you will use the two brackets supplied. The UV light housing simply clicks into the brackets. Once you’ve installed the brackets and housing, it’s time to slide in your globe.

Let’s begin the installation.

Install The UV Light

      1. Unbox your UV light system and unwrap the mounts.
      2. Unwrap the holders for the housing.
      3. Mount the holders to the wall. We recommend a horizontal installation but if you’re installing it vertically, make sure the globe/power leads go out of the top, never the bottom.
      4. Put the clip locks on.
      5. Unscrew both ends.
      6. Unwrap the glass thimble.
      7. Gently slide the glass thimble into the UV system.
      8. Unwrap the O-Rings and put one on each end of the glass thimble. These push up against the thread when you put the caps on.
      9. Put the stainless steel caps back on either side of the UV system and tighten them up as tight as you can by hand. You must seal it properly, but do not use any tools to tighten it, hands only.
      10. Wrap some thread tape around the thread of both the in and out pipes.
      11. Connect up the in and out pipes.
      12. Turn the water on and run water through the system, without any electricity.
      13. Flush the toilet, turn the shower on, turn on some of your taps and check that the UV system isn’t leaking.
      14. Once you’ve established there are no leaks, turn the water back off.
      15. Remove the globe from the packaging.
      16. Slide the globe into the thimble. If you have mounted it vertically, make sure you don’t drop the globe in, it will break the thimble.
      17. Plug the controller into an RCD, and then plug the RCD into the power outlet.
      18. Mount the controller somewhere and make sure it’s going to stay dry.
      19. Plug the power cord/controller into the bulb and push it into the housing.
      20. Put the rubber cap on to seal it up.
      21. Take off the nut where the earth wire goes and connect the earth wire.
      22. Put the nut back on and tighten up the earth wire.
      23. Ensure the power cord is directed down, so any condensation won’t trickle into the globe.

Now you’ve successfully installed the UV light with your Whole House Rain Water Tank system.

Caring For The Electrical Box

The electrical box is not waterproof. Wherever the electrical box is mounted, it must stay dry. Please watch the installation video to see the best setup for your electrical cable.

What you need to do is have some form of RCD or a power trip meter. It can be just a power pack with a little red button on it or a computer one that plugs in three-pin plugs in it, but just some form of trip meter that just stops the globes from blowing because they are susceptible to blow if there is a sudden change in voltage.

Caring For Your Globe

The globe will run for 12 months (9,000 hours) before it stops working properly and needs to be replaced. Note that even if after 9,000hrs of operation, if the globe is still on, it will not be killing any bugs.

If you’ve had the globe on for 9,000hrs, it’s time to be changed.

When you change the globe, it’s essential to check the glass tube is clean. If it’s not clean, the UV light will not penetrate the glass and sterilise the water. If it’s dirty, simply take it out and wipe it over, so it’s nice and clean.

If the glass tube is just too dirty to be cleaned, simply order a new glass tube/thimble for your UV light; they’re not very expensive.

Whenever the UV light is switched off, it requires 15 minutes to warm up and get going before being used.
