I have a drain gully at the back of the house which is just used for sinks to drain into, but recently it has started to bubble up a couple of times whenever a toilet is flushed in the house.
I'm not sure if this is relevant but I've tried poking a stick into the drain and it seems to have a lot of gravel at the bottom and I can't seem to feel any continuation of the pipe that would let the water out, is it possible that this is a blockage that might be causing it?
