How can I stop this valve? Please advise

[Novice diyer]

Hi,

I am very new to home DIY and am not sure I know terminologies well but I am replacing my washing machine and need to disconnect my old machine. I will need to shut off the tap but have no idea how to work this valve. Can any one with experience please give any advice? Thank you!

The valve would normally have a blue plastic fitting that you could turn by hand.....its obviously missing but if you have an adjustable spanner to fit on the flats of the valve you should be able to turn it 90 degrees to the off position.

Thank you for the quick response, John. I used pliers to turn it clockwise. It seems to go over 90 degrees several times though and it doesn't seem to stop the water flowing. Is there a different mechanism to shutting the flow?

The valve will actually spin round and round, but if you can turn it exactly 90 degrees the water will stop.
A few degrees either side and the water will start to flow again.

Just turn it to the 90 degrees and it will be off, that is with the flats horizontal. It will go round and round, you just needed to turn it one quarter turn only.

A ball valve is only shut when you turn it exactly 90 degrees.

too far, or not far enough, and it will be open again.

Use the flats on your spindle as a guide.

It's time you bought a new valve, but as you have plastic pipe I don't know which one you need.
