This model is supplied with a standard installation kit suitable for traditional, vented plumbing systems with a storage tank, connected to a 15mm mains supply. The kit includes a pair of 3/4" inlet/outlet, 600mm long white hoses and a rapid-fit hi-flow bypass for easy installation. Additionally, a complimentary water test kit is included with every Monarch Mini Aqua water softener. It is recommended for families of 4-7 people in hard water areas or 4-5 people in very hard water areas, assuming 160 litres per person per day usage. Advantages of the High Efficiency Monarch HE Mini Aqua Water Softener include: a higher flow rate (up to 83LPM) than other UK water softeners, the lowest pressure drops, and meter-controlled softening with proportional Opti-Brining as standard, which regenerates only used resin.

It offers a fast 8-minute mini top-up regeneration, a compact design (28mm shorter), and FreeFlow valve technology for the highest flow rates with the lowest pressure drop. It is designed exclusively for the UK market. Monarch Opti-Brining is a unique system that monitors softener activity and water usage, regenerating only when necessary to save water, salt, and energy.
