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

The Monarch HE range of water softeners all feature Monarch Water’s 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 Rapid-Fit bypass, installers simply connect the water in and out from the mains supply, then connect two hoses to the

The Benefits of Soft Water

The installation of your Monarch Midi will bring immediate benefits to both you and your water system.

As soon as you turn on the tap you will feel the luxury of soft water. Gone will be the days of using twice as much soap as necessary because with soft water the lather comes easily and lasts longer.

Your glasses and dishes dry spotless and there will be no need to put anymore salt in your dishwasher thanks to your Monarch Midi.

The cost of washing powder shampoos soaps etc will be reduced by up to 50% and will truly prove beyond doubt that soft water saves you money.

You will see a difference in the time with a Monarch Midi water softener spent cleaning baths sinks taps and shower screens. Never again will you return to find then covered in scale and scum the moment they are used with soft water baths stay bright taps sparkling.

Probably the most important benefit of soft water with a Monarch Midi will be noticed in your hot water system. As soon as a Monarch Midi water softener is installed it will begin to descale your system and increase its life expectancy. With no scale to heat first you immediately start to save on heating bills by up to 70%.

This pipe fitting was only 2 years old before it became blocked with scale. An average hardwater home builds up one sixteenth of an inch of scale per year (approx). Remember you have to heat the scale before you can heat the water. That's why scale costs you money.

Remember with Monarch Midi soft water flowing through the system your taps and pipes will become scale free and with no hard water in your system fitments like your shower will run as new!

Why choose a Monarch Water Softener

There is something very special about a Monarch Midi Water Softener the secret lies in the resin. It is the resin used that determines the quality of your soft water. Every model in the Monarch range uses a specially purified Food Grade Resin that guarantees you not only soft water but soft water of the highest quality.

Whilst reliability is important we believe space is also an important consideration and have endeavored to produce a water softener as compact as possible. From the slide-on rear cover to the high capacity resin vessels every Monarch Midi water softener has been built without compromise. Also comes complete with a 2m cable so you can install your softener a fair distance away from a mains point.

All Monarch Midi water softeners that we stock are meter controlled with the added features of a clock and their unique Self Protect Programme (SPP). They measure the water used and regenerate to individual household requirements. The intelligent chip and the clock ensures there is enough soft water available to delay the regeneration until 2am* a time when little if any water is being used.
*Time can be changed to suit individual requirements.

Peace of Mind
European regulations state that a minimum 2 year guarantee should be provided. With Monarch Midi Water Softeners the guarantee is much much more. With the proven reliability of the Monarch Midi they give an additional 5 years guarantee totally free of charge - giving you 7 years of total peace of mind. (Warranty is 7 years parts and NOW 2 year labour free of charge). Additional warranty is available at extra cost.

Monarch has been making water softeners for nearly 40 years and for the majority of them we have used the Autotrol control valve. This valve is arguably the most reliable there is with over 200 000 sold worldwide every year. Proven performance reliability and efficiency supported by our 7 year guarantee ensures that the Monarch Midi Water Softener you choose is the ultimate water softener.

In addition to the installation kit and flexible hoses every Monarch Midi water softener includes a complimentary water test kit.
