Water stopcock

[Kelley123]

Hi there, hope you can help! We have lost the 'key' that turns off our water - dropped under the floorboards and gone for good. But we don't know what it's called to try and find a replacement. Have tried a few, such as a lockshield key but no good. Have attached a photo and as u can see it needs something that screws into it.
Thanks if you can help, we are rubbish at this type of thing!

unfortunately you will have to buy the whole stop tap

unscrew the center screw on the head and swap them over

Have you got an outside tap? Should be the same handle as your stopcock.
