how do I change the washer on a Bristan 1901 basin tap?

have taken the cap off, but the screw under the cap won't turn, am I supposed to be unscrewing this? thanks

Bristan Bristan 1901 D.I.Y, Plumbing Washer Tap Turn

Hi Emily - usually the situation is this...under the tap cap there's a smaller hexagon nut that the stem passes through - this is the gland nut and it stops the tap leaking through itself, if you see what I mean. To access the washer though, the larger hexagon nut beneath is the one to undo. Biggish spanner needed - and water turned off, naturally! Cheers John

thanks John, can you just confirm am I supposed to be unscrewing the screw under the cap?

The large hexagon nut needs to be released to access the washer - the whole tap insert then comes out. These are often very tight indeed, and you need a large spanner or other gripper to hold the tap itself while you undo the nut. If the whole tap starts to turn there's a good chance it will leak.
