Thoughts please about possible cistern issue

[paul bing]

Hi everyone,

I have a problem with my outside loo (yes, some old houses still have them!) I can hear the sound of water running through the pipe which runs into the cistern. It is like the noise the cistern makes after being flushed but when it is almost re-filled (a low level noise if you see what I mean). There is nothing coming from the overflow. I use this loo as a storage (dumping) space so I haven't yet had time to clear it and inspect the cistern but I think that may be where the noise is coming from. Any ideas what could be causing this, what I should look for and how perhaps I could fix it.
The stopcock is jammed in the 'on' position, so I can't isolate the supply. I'm going to get my plumber to fit a new one so I can turn the water off altogether permanently, but until he comes I thought I'd ask if there is anything I can do to stop the noise?

Thanks.

Can't be 100% but if it's and old galvanized feed coming from floor and your toilet isn't overflowing then more than likely the pipe underground has burst giving the sound of running water.

Either the syphon is passing? Or the inlet valve isn’t shutting off? Or a leak on the cold inlet pipe to the cistern

Thanks for the replies. The same thing happened over the winter but the noise mysteriously disappeared. No issues since yesterday. As I said the toilet itself if full of junk. I don't know if any wether is trickling into the pan, but from what I can gather (and it's only a guess) the noise seems to be coming from the cistern. I hope its not a burst pipe!

I've just been on the phone to my plumber about having a new stopcock fitted, but can I ask a couple of questions here?

I think the rising main from the stopcock to the cistern is copper (I'll know when I clear the place and check tomorrow) but it will be imperial as opposed to metric. Any issues surrounding this or if it is a lead pipe? Is it possible to fit a new stopcock? Also I have thought about having the supply to the toilet capped off or an outside tap fitted above the stopcock. If so I will remove the toilet bowl and cistern and just use it for what it has become.

just need to tell your plumber if its lead but a new stop tap can be installed no problem on either

and thats fine also just need to tell the plumber incase he needs to get bits etc
