Monarch Water celebrated its 55th Anniversary in May 2019. It is the leading supplier of water softeners and CBT scale inhibitors to plumber’s merchants and builder’s merchants, both national groups and independent family owned businesses throughout the UK. Their softeners are covered by up to 7 year warranties (2years labour) and have the highest flow rates of any domestic softener available. To complement their main Ultimate softeners, a range of non-electric units under the Plumbsoft brand with 5 & 2 warranties, are available covering 1 – 15 person applications. In August ’13, Monarch successfully launched Scaleout. Scaleout is a unique scale prevention and removal system that uses Ceramic Bead Technology (CBT) that once the water has been treated, gives a permanent solution to the effects of hard water. The resin within the Scaleout lasts a minimum of 3 years before it needs changing.
