Replacing A Toilet Fill Valve

Introduction

helpfulcolin.comI am in the process of making some changes and additions to this post. Please bear with me.


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.

Repairing A Toilet Silent Fill 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.

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 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”.

Should You Worry About Your Bath Overflowing?

“Me, worry about my bath overflowing? Its got an overflow pipe.”

“Oh! Has it?”

Why you DO NEED to worry about your bath overflowing?

I know someone who has had a bad experience with a bath overflowing, but it wasn’t their bath overflowing. It was in a flat two floors above. Interestingly the flat in between on the floor immediately below the bath didn’t get wet. How can that happen?

Well lets start with the overflowing bath. The person, whose bath it was, admitted it had overflowed but not very much. I suspect this means that the water did actually run over the rim of the bath. That means it rose above the bath overflow outlet (assuming there was one.) On my bath, water would start to go down the overflow pipe when it is within 8cm of the top of the bath. The top of my bath is 8cm above the bottom of the overflow. So if it is full to the point where it will overflow the rim of the bath the head of water pushing out through the overflow will be 0.08m whereas the head of water from the water level in my header tank in the loft is 2m. Alternative forms of hot water provision can be at mains pressure which usually has a lot more than 2m head. My point is that the tap’s pipe diameter and overflow pipe diameter are similar but the input pressure is a lot higher than the output pressure. Consequently baths can fill faster than they can overflow. So eventually a system with no faults may eventually overflow the rim of the bath if the taps are turned full on. So DON’T LEAVE BATH TAPS RUNNING WHEN YOU LEAVE THE BATHROOM. You may be distracted and forget about them. Continue reading “Should You Worry About Your Bath Overflowing?”
