Bit of a funny one.
Got back from 2 weeks visiting family and the upstairs bathroom soil stack is now making a noise I can only describe as an echo of filling water when I either flush the bog upstairs or even worse noise when I run the basin taps.
Can't see any evidence of backfilling but it didnt do it before I left. Its like I can hear the noise from the ground floor coming up the pipe to upstairs.
