My mains pressure has always been a steady 1.5bar, About a week ago it reduced to about 0.2 The inlet stop cock and pipes make a hissing sound. Pic 1 shows water main A, but there is also an odd thing. If I put my ear to toilet drain downpipe B, there is a clear sound of running water in it. Here’s what I've checked. When the stopcock is off, both sounds remain. When the stopcock in the road is off, both sounds stop. Mains supply in road has been checked by TW and aok. There is nothing going down the toilet drain (condensate, toilet leak etc).
So it's, likely I have a supply leak on my side? I cannot see any external signs of a leak. Is it possible that beneath my slab the water main pipe runs into and through the toilet drain. I'm sure I must have a leak but cannot understand why the running noise is coming from the toilet drain?
Hi gavski1 Sounds like you have a serious leak on your mains in. It could be the mains pipe runs close to the waste pipe hence you can hear running water. Regards S
Thanks for the reply, guess I'm going to have to get someone to have a look - do you know if that would be a plumber, or will I need a specialist leak detector. There are no obvious signs like any damp pateches, cheers
Hi gavski1 Search for local companies that specialise in replacing mains water pipes - they may be able to trace where and if there is a leak. Hopefully you are not on a water meter. Regards S

Thanks for that, fortunately I'm not metered at the moment.
