Water Treatment

Our water treatment category covers spares and consumables for domestic and commercial systems, including filter housings, cartridges, dosing components and replacement parts. Whether you are maintaining a combi boiler, unvented cylinder or a standalone treatment unit, we aim to help you find the correct part first time. All fitments are checked by our technical team before dispatch, so you can order with confidence. In-stock orders placed by 4pm Mon–Fri (10:30am Sat) are despatched the same day. We offer 30-day returns on most items. For obsolete or discontinued items, send us the part number and we will do our best to source it. Call 01302 279234 or visit our Doncaster trade counter.
