Filling Valves

The filling valve is a crucial component of your toilet's flush system, responsible for filling the cistern with fresh water for use. If the filling valve develops a fault or fails, it renders your toilet unusable. Additionally, older filling valves may not be as water-efficient as modern counterparts, making an upgrade a sensible choice. The filling valve plays a role in preventing overfilling of the cistern.

Our selection includes products from top manufacturers like WirquinIdeal Standard and Geberit.
