This Fluidmaster side entry cistern filling valve is an ideal choice if you have a side entry water inlet with the smaller European thread. This is a reliable replacement for valves with a 3/8 BSP thread and is a valve preferred by professional plumbers. The thread is made of brass, this is much better than ordinary plastic threads as it stops any cross-threading. The blue cup can be fully adjusted so to fill up your cistern to the level you require.
