Replacing A Toilet Fill Valve

Introduction

I have already written about making a Toilet Silent Fill Valve Repair, but whether a toilet fill valve is silent or not it can’t always be repaired. So I have written this article about replacing a toilet fill valve to help those who need to get a new one.

I have also written another article about How A Toilet Silent Fill Valve Works which is appropriate to a specific type of fill valve.

How A Toilet Silent Fill Valve Works

Introduction

This article is in effect an addendum to the post Toilet Silent Fill Valve Repair which explains how to access and dismantle such a valve and inspect or change the diaphragm that sits in the valve. That post also explains what is, and is not, silent about a Silent Fill Valve. This is now complemented by the post Replacing A Toilet 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:

  1. A Valve.
  2. An Inlet Valve.
  3. A Cistern Inlet Valve.
  4. A Toilet Cistern Inlet Valve.
  5. A Silent Fill Toilet Cistern Inlet Valve.

This type of valve is complex and deploys a built-in mechanism which uses the inherent water pressure in the Mains Water to drive the valve from the closed to open position and then from the open to closed position. The mechanism is controlled by a much smaller valve in the form of a stopper covering a pinhole which requires a much smaller effort to operate it than the main valve.

The article endeavours to explain to the reader how the complete valve works so that they understand the order in which physical processes take place and why they follow on from each other as they do. The theory behind the workings of the valve are developed from the basic principles of forces and pressures acting on the individual parts but without the detail of too many mathematical formulae.

Repairing A Silent Fill Valve Used In A Toilet

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:

  1. A Valve.
  2. An Inlet Valve.
  3. A Cistern Inlet Valve.
  4. A Toilet Cistern Inlet Valve.
  5. A Silent Fill Toilet Cistern Inlet Valve.

Repairing a 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”.
