Help fixing leaking tap

[rich99]

Hi,

I've attached a picture of a bathroom tap. I've taken the handle off, and it's easy to see that when it's turned on (it's a twist & lift style tap), water leaks into the top & eventually drips over the sides. The problem is how I stop this! I can't see how to get to anything, or anything ti tighten. Looking down the top, there might be a nut style rung around the blue ring you can see on the top, but I can't get to it. It looks like there's a join between the bevelled top & the rest of the tap, but it doesn't obviously unscrew.

Anyone with experience of these types of taps know how I get it apart, and what I might need to tighten to stop it leaking when it's turned on?

Thanks!

the bevelled top unscrews ,anti clockwise. exposing a large hex nut which keeps the valve in place. you can get replacement valves ,but there's quite a few variations so you may have to go on a mission to match yours.

Excellent, thanks for the info. The beveled top is on pretty tight. Any idea what I could use to get it off without damaging it?

gets limescale build up on thread and makes it stubborn.!! try pouring boiling hot water on to expand a little ,then wrap a cloth around to protect chrome and you then need a gripping wrench with wide jaws on it. like water pump pliers.

if your very lucky tightening the hex nut a little may stop your leak ,but more likely the valve needs replacing.

Ok, thanks for all the help, I'll give it a bash later this week.

Right, stupid question time. I'm struggling to get an adjustable spanner in to the nut, because it's slightly recessed, so I went to buy the right size spanner. The nut is 30mm wide, so I bought a 30mm spanner. However it's too big. What size spanner is needed for a nut that's 30mm across?
