We're on a shared sewer (4 houses) and the last house before it goes into the road have recently paved over their front garden (and covered what I assume was a vent -little cast iron thing about 150mm high). Since then you have to flush the toilet 2-3 times to clear the turds, I imagine due to negative pressure in the pipe? As this vent is situated within the end property boundary, presumably the water board cannot insist he reinstates it. Anyone got any experience of this kind of thing? I'm sure it's not the first time old vents have been covered up during makeovers. The flush seems perfectly normal and there's no evidence of a blockage of any kind. TIA
