Turn Tap On then Toilet Flushes

Postby suntanmandan » Tue Jan 20, 2009 10:53 am

Hi, i hope someone can help with this strange prob im having. I had a new bathroom suite installed downstairs last year, working fine uptill now:
When i flush the toilet (its one of those button flushes, either half or full flush), it flushes as expected, but if i then turn either the basin tap or kitchen tap on the toilet begins to flush again. Well it's not exactly as fast as a normal flush, and continues flushing indefinetely until i flush the toilet again.

I have though about stripping all the gubbins down from inside the cistern, maybe somethings wrong there?

Yes, the plunger thingy in the cistern is stuck in the up position - take it out and clean it.

From what you describe it sounds more like the cistern is overflowing (if you didn't know, modern cisterns don't overflow to the outside through a pipe, but down into the pan itself - this is why it appears that is is constantly flushing).

As to why opening the taps causes this, not entirely sure why a reduction in pressure on the valve should cause it to open and remain open which will cause the subsequent overflow. Not too difficult nor expensive to replace this inlet valve fitting.
