How And Why To Flush Your New Water Filter Replacement Cartridges [VIDEO]

In this article, you’ll learn how to flush your new Benchtop Water Filter Cartridges before use.

In many cases, when you purchase a water filter, it needs to be flushed before use. This is because there are a lot of fine particles that come out of many cartridges when they’re used for the first time.

A problem arises when the fines from your new fluoride or alkaliser cartridges flow into the Ultrapure cartridge and clog it up before you can say, “Oh my gosh, this water tastes good!”

CHECK YOUR CARTRIDGES FOR FAULTS

Before you start installing your new cartridges, you always need to check for any damage they may have been sustained in transit from the warehouse. You can do this by twisting it at each and giving it a good “look over” to see if there are any cracks, chips or if it’s broken.

See our new cartridge inspection guide if you need help with that.

HOW TO FLUSH A WATER FILTER

If you just have an Ultrapure Single Stage Benchtop Water Filter, simply connect it up and flush water through for 10 minutes, and you’re done.

HOW TO FLUSH THE CARTRIDGES IN YOUR TWIN BENCHTOP SYSTEM:

If you connect your new water filter and start using the water straight away, the water will blow all of the fines out of your first cartridge/s into the Ultrapure cartridge. What you may get, as a result, is a blocked Ultrapure cartridge, which can slow down the water flow significantly.

If you're not using a fluoride removal cartridge, you simply put in your cartridges and flush it for 10 minutes. 

If you are using a fluoride removal cartridge, flush the system using the process below:

      1. Remove the housing from your Ultrapure cartridge using the cartridge removal tool.
      2. Take out the Ultrapure cartridge.
      3. Put the housing back on and tighten it up.
      4. Turn on the water and let it run through your fluoride removal filter for 10 minutes.
      5. Remove the housing on your Ultrapure cartridge again, and insert the cartridge back in.
      6. Turn on the water and let it run for another 5-10 minutes.
      7. Pour a glass of water and check it for any fines.
      8. If your water is clear, do a happy dance; you’re done!
      9. If there are still fines in the water, flush it again for another 5-10 minutes. 

HOW TO FLUSH THE CARTRIDGES IN YOUR TRIPLE BENCHTOP SYSTEM:

If you have an Ultrapure Triple Benchtop Water Filter, sometimes you’ll find a sediment cartridge in position one. You don't need to flush a sediment cartridge, it’s the cartridges in position two and three that need to be flushed.

If you're not using a fluoride cartridge, simply install the cartridges and flush it for 10 minutes and it'll be ready to use.

If you are using a fluoride cartridge, follow the process below to flush your Triple Benchtop system:

      1. Remove the housing from your Ultrapure cartridge using the cartridge removal tool.
      2. Remove the Ultrapure cartridge and put the housing back on. Your Ultrapure housing should be empty.
      3. Remove the alkaliser or calcite filter and flush the fluoride filter on its own for 10 minutes. 
      4. Put the Ultrapure and the alkaliser/calcite filter back in and flush for another 10 minutes.
      5. Pour a glass of water and check it for any fines.
      6. If your water is clear, do a happy dance; you’re done!
      7. If there are still fines in the water, flush it again for another 5-10 minutes.

Tip: Always make sure the cartridge is inserted correctly.

For benchtop systems: “This way up” actually goes down.

For undersink systems: “This way up” goes up.

WHAT IF THE FLUORIDE CARTRIDGE IS IN POSITION ONE?

All Fluoride removal cartridges MUST be FLUSHED with flowing water inside your water filter for 10 minutes minimum with NO other cartridges installed before use.

No matter what cartridges you have before your Ultrapure cartridge, you always need to remove your Ultrapure cartridge to flush the other cartridges before the water is put through.

Follow the process below:

      1. Remove all water filtration cartridges from inside your water filter, noting the position of each cartridge. Note: Your Fluoride Removal Cartridge is normally installed into positions 1 or 2 in your water filter.
      2. Install the Fluoride Removal cartridge inside the water filter, with NO OTHER cartridges installed after the Fluoride Removal Cartridge.
      3. Turn on the water, and let water flow through the water filter to flush the Fluoride Removal cartridge for at least 10 minutes. (This water can be collected for plants if so desired).
      4. After flushing water through the Fluoride Removal Cartridge for 10 minutes minimum, turn off the water supply, turn on the drinking water filter faucet to release any water pressure.
      5. Remove the housings for any other cartridges you need to install. Install these cartridges in the same order & positions they were removed from.
      6. Tighten all housings, turn the water supply back on and check for leaks.
      7. Turn on the water filter faucet and flush the full system for a further 10 minutes with ALL cartridges installed. 
      8. Pour a glass and check the water is completely clear. If the water isn't clear, keep flushing your cartridges for another 10 minutes.
      9. After 20 minutes of flushing cartridges, you’re probably ready for a drink. Pour yourself a glass of water and celebrate a job well done.

WHAT IF THE CARTRIDGES WERE NOT FLUSHED BEFORE FIRST USE?

If for whatever reason, you didn’t flush the cartridges before first use, you may experience a significant reduction in water flow coming out of the faucet.

If this is the case, you will need to remove the Ultrapure cartridge and clean it, using the process below.

HOW TO UNCLOG AN ULTRAPURE CARTRIDGE:

      1. Remove the housing on your water filter.
      2. Take out your Ultrapure cartridge.
      3. Hold the cartridge under running water and scrub it with a 60 grit scotch Brite scourer pad.
      4. Put it back in and screw the housing back on.

After that, follow the process above to flush the cartridges properly before inserting your Ultrapure cartridge again. This will give you a full flow of water again.
