Choosing, preparing and caring for this product

Check compatibility before treating an accessory as universal.

Compatibility

Match accessories, filters and installation components to the exact machine, tap, cooler or site requirement.

Installation

Some parts are intended for professional installation. If the job affects water, electrics, pressure, drainage or equipment internals, confirm the correct method first.

Consumables

Where an item has a replacement interval, base it on manufacturer guidance, usage and site conditions rather than a generic calendar rule.
