Water Filters

Hi-Flow Digital Backflush

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 Hi-Flow Digital Backflush system is designed to solve this problem.

Hi-Flow Digital Backflush

Built Into Our Flagship Whole House System

Hi-Flow Digital Backflush is built directly into our ES5Q Whole House Wellness System. It works automatically in the background as part of the filtration system.

There is nothing you need to do.

Once installed, the system performs a scheduled flush to clear sediment and protect the filter cartridge.

This technology allows the system to maintain high flow performance while still delivering multi stage filtration.

ES5Q Whole House Water Filters

Why Backflush Matters

Without backflushing, sediment stays trapped inside the cartridge and gradually restricts water flow.

With backflush, that sediment is removed before it builds up.

This delivers several important benefits.

Consistent pressure -across the home
Showers, taps and appliances maintain stronger water flow.

Longer cartridge life -
By clearing sediment regularly, cartridges can last up to twice as long.

Lower maintenance costs -
Fewer replacements and less servicing over time.

Better long term performance -
The filtration system continues operating at optimal flow levels.

ES5Q Whole House Water Filters

Designed For High Flow Homes

Whole house filtration needs to deliver both clean water and strong pressure.

The Hi-Flow Digital Backflush system helps achieve both.

By preventing sediment build up, the system protects the filter, maintains pressure and reduces ongoing maintenance.

It is one of the key reasons our flagship ES5Q system is designed to perform reliably for the long term.

Cleaner filters. Stronger pressure. Longer cartridge life.

That is the advantage of Hi-Flow Digital Backflush technology built into the Great Water Filters whole house systems.
