Plumbing: Change a ball valve on a toilet cistern

As a handyman I get called to many overflow problems.

There are many variations on this theme.

Whether its a toilet cistern, cold water tank, or the central heating header tank, the process is generally very similar.

I've taken a couple of photos while on the job to show you what neeeds to be done.

The object in question is a side entry low level cistern. It's probably the simplest to do.

In a ideal world the sequence is as follows:

1. TURN OFF THE WATER!

2. FLUSH TOILET!
(Let out at least some of the water)

________________________

3. DISCONNECT BALL VALVE FROM SUPPLY
(usually 15mm pipe - but not always)

_____________________________

4. UNDO BACK NUT AND REMOVE BALL VALVE
Normally two nuts hold the ball valve in place -
one on the inside and one on the outside.

5. FIT NEW BALL VALVE

Just reverse the order of doing the above.

Turn water on and check for correct function AND LEAKS!

I've said it before, and I'll say it again it's a simple process, but simple doesn't mean easy, and be aware, there are things that can go wrong.
