stop tap won't reopen.

[GaryHope]

Helping a friend fit a new flush mechanism to his upstairs loo. No ball valve so fitted one of those in the process, hence needed to stop water supply from cold water storage in loft. He closed the feed from the cold water tank, tap stiff but didn't need any force with a spanner (wrench/grips) to turn.

Job all done and time to turn the stop tap back on and it just goes round and round. Red tap head removed and the brass shaft turn easily but just keep turning. I can get a trickle of water flowing wafter a combination of tapping the stop tap body and pulling the tap had outwards.

My conclusion - tap washer stuck, needs a new tap. Beyond my 'pay grade'.

Any other ideas welcome

Thanks

If it was red handled it's a Gate valve and the thread normally wears or shears in the gate.
New gate valve (or lever valve) required, not a stop tap tho' as the pressure at the tank isn't high enough to lift the washer / jumper.

Gate valve it is - lazy layman talk here.

thanks for confirming though
