How A Toilet Cistern Silent Fill Valve Works

Introduction

This article is in effect an addendum to the post Repairing A Toilet Silent Fill Valve 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 Toilet Silent Fill Valve

Preface

This post describes: How to repair a Toilet Silent Fill Valve. Basically that’s how to replace the rubber diaphragm within the valve.

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.

Unblocking My Wash Basin Drain

Introduction

I recently noticed the waste water leaving my bathroom wash basin drain was taking more time than usual to drain away. Realising this meant a total blockage may be imminent, I set to work dismantling the waste pipe and bottle trap so that I could begin unblocking my wash basin drain. Boy was there some gunge to clear out.

Fixing Shelf Battens To Old Walls

Preface

This post describes: How I spent a day fixing shelf battens for two shelves in a house. The walls were old and not solid brick as expected. The walls crumbled when I drilled into them so I had to repair them and drill again.

Zipper Slider Repairs

Introduction

Here are two zipper slider repairs that can be done when the pull tab has come off and either:

  1. the crown (or lug) is lost,
  2. you still have the crown (or lug).

This post is an edited compilation of two posts I wrote on this blog in the past describing the repair of Zipper Sliders. I have updated the references and deployed WordPress SEO (Search Engine Optimization) by Yoast to improve visibility on the internet.

Dripping noise from a rainwater spout

Introduction

This post refers specifically to downpipes with a square cross section. It shows how to modify a rainwater downpipe spout (shoe) to stop a dripping noise when the drip starts within the outlet shoe.

For drips that drop off the guttering outlet and fall all the way down to the bottom of a straight downpipe and hit the shoe you may get immediate relief from the noise by removing the shoe and letting the drip fall on the ground, roof or whatever is below the downpipe. In the long term this may cause excessive splashing under heavy rain which could cause damage to foundations or brickwork mortar, because the water is not directed away from the building.

The drip needs to be guided to the side of the downpipe so it will run down the pipe and only tend to drip at the bottom where it can be dealt with by the method described here. Any method devised must not prevent leaves and dirt from being washed all the way down the pipe or a blockage will ensue.

Bed Headboard Wall Fixings

Introduction

This post describes a method for DIY readers to make and mount bespoke wooden Bed Headboard Wall Fixings, to my design, so that no bolts are visible and so the headboard can be removed by just lifting it vertically to allow for cleaning or horizontal adjustment. It gives a specific example. Other headboards will be different, but I hope anyone wanting to use this fixing method can work out how to do it with their headboard. I’m open to questions – just use the comment process.
