Hi there
We stay in a 4 bedroom detached house and have recently noticed a water flowing sound that appears to be coming from one of the main waste pipes in the house.
The pipe is downstairs from our en-suite bathroom but there is no noise coming from the cistern in the en-suite and no signs of leakage.
i do have a WC at the other side of the house which is constantly flowing and has a leak but not sure if this is what’s causing the sound.
Any help would be appreciated.
Cheers
