Opti-Brining® for sustainable softening

Opti-Brining® is Monarch Water’s unique, new system to manage water within its next generation of HE water softeners.

TheintelligentOpti-Brining® component continuously monitors the softener’s activity and water usage, regenerating only when necessary, to save more water, salt and energy than previous generations.

Opti-Brining® technology offers higher exchange capacity, higher flow rates and reduced water consumption during regeneration. With up to 46% greater capacity per regeneration than previous units for a truly sustainable future.


Hi-Flow Rapid-Fit bypass for easy installation

The NEW HE range of water softeners all feature Monarch Water’s NEW Rapid-Fit bypass which has reduced 85% of the components needed when installing a water softener.

Available for 15mm, 22mm and 28mm supplies, the Rapid-Fit also has 3/8” connections for both hard and soft water tee points. It also features a 1” high flow check valve built into the body to comply with WRAS guidelines, giving an impressive flow rate of 80lpm.

With Monarch Water’s NEW Rapid-Fit bypass, installers simply connect the water in and out from the mains supply, then connect two hoses to the softener for quick and easy installation.
