water dripping in toilet tank

[oldgirl]

Hope this is the right category.
I've water dripping in continuously from the valve (?) The bit that fills the tank after flushing. As a result water is going in the overflow.
When I raise the float ball, it stops.
There is a fair amount of scale in the tank and parts.
I adjusted a nut on the handle to its limit but hasn't helped. The ball valve handle is plastic.
What can I do?
Thank you

How hard are you pulling up the arm to make it stop?

Also unscrew the float ball and check its not got water in it.

You could strip the valve down and clean but I personally would just replace the valve for what it costs.

You can buy a rubber washer from BnQ (if you can find someone on their plumbing department, as them which one. get them to show you how to swap it too). its pretty easy to change - I bet the one you have is gunked up with scale or is perished. Literally a 2 minute fix once you know how.


In fact, its been described on here many times.

Hi xr4x4. I'm pulling up by a very small amount.

For any repair would I have to drain the tank? If so do I just stop water by turning off the stop valve?

My guess is the ball has water in it, so will never float.

Check that first.

If its a side fill, just turn off the stop valve, if it's a bottom fill, yes you have to drain.

Checked ball. No water in it.

Then you need a new valve, or repair the old valve.

Sometimes the repair doesn't work, so I mostly always just replace.

Also I believe that the tank is many yrs old.i don't know whether that makes any difference to the mechanism that's there. Bn on u tube n can't see system like mine. Can't ask my husband when he replaced bits in it as Unfortunately he has recently developed dementia. He was a wizard with diy n I never had to worry in the past.
But I've learned a lot from him and like to have a go. With help from Good people like you.
Thank you.

 

[oldgirl]

Thank you. I'll try n replace it. Will let u know how I get along.

Sorry another problem. I turned off the stop valve supplying water to toilet tank. Flushed the toilet But a very small flow continues to flow. I hv turned off another app Valve which I know it's for the outside garden pipe.
What could b wrong?

 

[oldgirl]

Ok its stopped now. Sorry.
