We have had some alterations made to our house.
There are now three toilets, one above each other, and each connected to the same stack pipe.
This stack pipe finishes in the top bathroom.The builder has put something called a dorco / durgo(?) valve on the top of this. It does not protrude through the roof to the outside as I thought it would have to, and there is no other stack pipe in our house.
Does anybody know if this is correct?
Does it comply with Building Regulations?
Are there likely to be future problems?
Thanks
