toilet drips after being flushed for a while

[helptavner]

i have dismantled it all, cleaned the valve up havent replaced the washer (but it looked ok) was a bit mucky in there, but doesnt seem to have improved it (didnt replace the washer as at the time wasnt aware what sort it was and havent got one yet

it stops if you hold the ball up for a second. (like there is to much play and not making it switch off quicker) it does switch off in the end but takes a good while..

will a new washer improve it?

it it normal to drip for a good while after being flushed ??

toilet about 14 yrs old thanks

There should be an improvement although you'll find yourself still sitting there watching it drip for while muttering to yourself

Pretty much. If in doubt take it with you.

changed it this morning still drips for a fair few hours, pretty sure it cuts off in the end (as if you hold up the ball valve up)

should it really take that long??

thanks

Final thing you could try is to put that new washer in the other way round. I'm surprised that it's still taking so long to stop dripping. The only other reason could be a bit of pitting along the seal rim.

We are talking about a float valve with an arm which has a spherical plastic float, yes?
You've replaced the washer, but it still lets by, yes?

If it has a plastic seat

they can 'craze' and bits fall away causing a leak.

If it is a Part 1, 2 or 3 float valve with a spherical float, get rid and fit something decent - a Fluidmaster, perhaps.

You may find the problem is the ball valve nozzle. I've had one with a crack in it and another where a groove was worn in it.
If your'e changing the diaphragm it makes sense to change the nozzle at the same time. about £1-30 from B & Q

Try an independant merchant. They're not that greedy!!
