High-Flow Auto Dirt Flush

Every home has sediment in the water supply. Even treated town water carries fine particles such as sand, rust, scale and organic debris. These particles are tiny, but over time they build up inside water filters.

That build up is the main reason water pressure slowly drops in many filtration systems.

Showers feel weaker.
Taps flow slower.
Appliances take longer to fill.

It is not a failure of the filter. It is simply sediment gradually clogging the filter media.

Most standard filtration systems trap this dirt but hold it inside the cartridge. As the sediment accumulates, water has fewer pathways to flow through. Pressure drops and cartridges need replacing sooner.

The High-Flow Auto Dirt Flush system is designed to solve this problem.

High-Flow Auto Dirt Flush

The Problem With Standard Water Filters

Every home has sediment in the water supply. Even treated town water carries fine particles like sand, rust, and scale.
Over time, this build up blocks your filter.

The result:

  • Showers lose pressure

  • Taps run slower

  • Appliances take longer to fill

  • Cartridges need replacing sooner

This is not a fault. It is how standard filters work.

They trap sediment but hold it inside.

The Smarter Solution

The High-Flow Auto Dirt Flush system is designed to clear sediment before it causes problems.

Instead of holding dirt inside the filter, it removes it automatically.

This helps maintain:

  • Strong water pressure

  • Cleaner filter media

  • More reliable system performance

Clean water at every tap without the drop in pressure.

How It Works

Automatic Dirt Flush Every 7 Days
The system performs a scheduled flush to remove trapped sediment.
Sediment Is Safely Removed
Waste water is discharged safely, often into your garden.
Filter Stays Clear
Sediment does not sit inside the cartridge long enough to cause blockages.
Pressure Stays Strong
Water flows freely across the entire home.

Why Dirt Flush Matters

Without dirt flush:

  • Sediment builds up inside the filter
  • Water flow gradually slows
  • Cartridges clog faster

With dirt flush:

  • Sediment is removed early
  • Pressure stays consistent
  • Cartridges last longer

This is the difference between a system that slows down and one that keeps performing.

Key Benefits:

  • Consistent Pressure Across The Home
  • Longer Cartridge Life
  • Lower Maintenance Costs
  • Reduced Sediment Build Up
  • Better Long Term Performance
  • Clean Water At Every Tap

What Customers Say

“Great service and support. Great Water Filters send me an annual reminder when my filters are due, they keep records so I get the right filters at the right time.
Support is unparalleled. I get help when I need by phone and in the event of something going wrong, Great Water Filters had a representative from WA to help resolve the issue in one visit.
Phone support, ordering additional filters (for showers), and response times are excellent. I recommend them highly!”

“Quality finishes, water and customer service. From meeting Paul at the Home Expo, to engaging with Levon to help plan and work through all our queries and ultimately to Shannon implementing the system we're delighted with the result and enjoying the filtered water at every tap point in our home...and without loss of pressure. Thanks Great Water Team!”
Yianni S.27 August 2024
“Fantastic experience from start to finish. No pushy sales like the other company we enquired with. We kind of knew what we wanted, and any questions we had were answered honestly and concisely. We’re loving having filtered water throughout the whole house with no noticeable water pressure loss. Thanks for being such a wonderful company to deal with. I have already recommended the whole home filtration system to several of our family and friends”
Christie K.27 August 2024
“Very happy with the quality of the product and the service. We have gone from having dirty, hard water (awful town supply!) to clean water that feels soft after the installation of a whole-house filter. The whole process was quick, taking less than a week from my first approach to Great Water to the filter being installed. The plumber assigned was friendly and professional. A very small amount of seepage we had after installation was fixed within a day after one text message to Great Water. While the price may put some off, we see it as a saving on the jug filters we no longer need to buy, and on the damage the old hard water used to do to the bathroom, kitchen and cars. I would definitely recommend Great Water's household filter system.”
