Help From A Plumber Re. My A.shanks Toilet Problem!

[moggie 939]

Hello
I am elderly and before replacing the unit in my Armitage Shanks Close Couple toilet may I ask a question? The toilet is the one with the button on top giving choice of two flushes and is marked inside 'fill delay'.

My problem is that it is dripping inside the 'workings' all the time - not a lot but I removed the top and to the left there is a blue part (sorry to be vague) and under it is some sort of valve from which the water drips all the time after the fill up has occurred.
The cistern only fills up to about 8"" or so and there is no problem with the flush and the dripping does not occur in the toilet bowl at all.
Should I get the unit replaced as my wife thinks it will use a lot of water - but the cistern never fills up above it's level in between flushes and when we were away for a few days it was normal when we returned,
Where the water is dripping does not seem to be an overflow and we have a wetroom in our apartment with no outside overflow.
Any advice would be appreciated.
Thank you

It is almost certainly just the valve that controls the water fill that needs replacing, they have a limited life and need replacement after a few years. Main problem is they get clogged up with limescale in hard water areas.

Modern flush valves have a built-in overflow that sends the water into the bowl so they don’t require the old-fashioned overflow pipe out of the building. If you are not seeing any water going into the bowl there can’t be much water dripping. However, it is hard to see the water going into the bowl as it doesn’t drip but trickles down the back of the bowl and you often only notice because the area where it is trickling gets discoloured over time. As Eddie says, these things have a limited life and do need replacing, it is a question of how much water you are losing and how much it annoys you as to when you replace it.

Thanks both of you - I will keep an eye on it. Looking at the complete unit and putting in a part number my son said the whole unit is less than £30.00.!

Thanks for your help
