I have a small leak from the water inlet fixed to the wall that attaches to my washing machine. I think it’s coming from the valve itself as when I turn the valve to off position, the drip does not stop. 
 

Anyone around to fix it? You’d need to get the parts (toolstation is a few mins walk away if needed).
