£699.99 Including FREE Delivery

The Tapworks AD11 water softener was one of the UK's most popular domestic water softeners, helping homeowners permanently eliminate hard water problems while supplying fresh, softened water throughout the home. Designed for households of up to 5 people, the AD11 became a trusted choice for protecting appliances, reducing limescale build-up, and improving water quality every day.

Please note that the Tapworks AD11 water softener has now been discontinued. However, if you are looking to replace your existing AD11 system, a modern like-for-like replacement is available.

The recommended direct replacement is the NSC11PRO water softener, offering improved technology, high flow rates, smart metered operation, and easy installation compatibility for existing Tapworks systems. The NSC11PRO is designed as a direct replacement option for AD10 and AD11 models.

Why Choose a Replacement for the Tapworks AD11?

Replacing your older AD11 water softener helps ensure continued protection against hard water and limescale problems throughout your home. Hard water can affect boilers, showers, taps, washing machines, dishwashers and pipework, causing scale build-up and reducing efficiency over time.

The modern NSC11PRO replacement continues the proven Tapworks approach while offering enhanced performance and water-saving technology. It is suitable for homes from 1–8 occupants and provides efficient water softening only when required.
