Water Treatment & Softeners

24 bargains

Hard water areas keep scale protection on the fitting list for nearly every boiler swap. Live discounted prices on water softeners, inline scale inhibitors, filter housings and replacement cartridges are compared here from UK suppliers, biggest markdowns first. An inline reducer is a cheap add-on at the right price, and multipack cartridge deals are worth watching for.
