Introduction
I recently heard my cistern overflowing. On investigation I decided to adjust the float level to stop it by reducing the height to which the water in the cistern rose when it filled. A few days later I heard the distinct sound of the cistern overflowing again. I then realised I needed to repair my Toilet Silent Fill Valve.
In order to satisfy the requirements of Internet SEO (Search Engine Optimisation) the valve is referred to, in this article, specifically as a Toilet Silent Fill Valve or more generally Silent Fill Valve but its full title is a Silent Fill Toilet Cistern Inlet Valve since it is:
-
A Valve.
- An Inlet Valve.
- A Cistern Inlet Valve.
- A Toilet Cistern Inlet Valve.
- A Silent Fill Toilet Cistern Inlet Valve.
Repairing a Toilet Silent Fill Valve used in a toilet is, in my opinion, easier to perform than one on a traditional ball valve (ball cock). Modern inlet valves take up the minimum of space with their small float, are made of plastic and can often be dismantled by strong hands without any spanners because their screw threads don’t jam with calcium and corrosion like brass ones. They are available in various formats. Some mount through a hole in the side of the cistern, and are a good replacement for old brass ones (which are usually mounted that way), while others stand on a tubular stalk inside the cistern which mounts through a hole in the bottom of the cistern. When the fill pipe is attached at the bottom of the cistern the pipe can often be situated out of sight. Bathrooms look much nicer and cleaner when pipes are out of view.
It may be that a Replacement Fill Valve is required. If so take a look at my article “Replacing A Toilet Fill Valve”.
