All about me

Limescale affects your pipework, boiler, radiators, taps, appliances and fittings and can lead to increased repairs or early replacement costs. McAlpine Scale Defender can save hundreds of pounds as it keeps your heating system more efficient and helps prolong the life of pipes, fittings and appliances. It is especially beneficial if you live in a hard-water area, but can also help households in soft-water areas too!

This easy-to-install system doesn't change the taste, smell or colour of the water, and is completely safe for drinking (BS-EN 1212).

This has a patented dosing system for accurate dosing. It has a visual indicator for replacing the cartridge, and we sell these refills too. It comes with a prefilter, and lasts around 40,000 litres of water on average! So it should last around 1 year before you have to change the filter. Everything you need is in one box, including the brackets and internal reducers for 15mm.

This product comes with WRAS approval from the supplier. What is WRAS? WRAS is an acronym for Water Regulations Advisory Scheme and this product complies with byelaws and water fitting regulations. Commercial properties often require this certification, so if you need it then this product is for you!

This boasts an amazing lifetime guarantee. Register your McAlpine Scale Defender system for your FREE lifetime guarantee at
