I have 2 types of soil stacks in my bungalow :
The first is in my internal ensuite which runs into the attic and then vents externally through the roof.
The second is in my main bathroom and only runs to a height of 1.5m, where there is a white cap which can be unscrewed (I'm assuming this is for access to clear blockages)
Why does the second stack not vent externally ? Does the second stack need to be at this height or can I reduce the size to 1m ?
The reason for asking is I'm undertaking my second bathroom fit out and looking to box up the wall with the stack up to 1m as this will hold all the toilet, sink, and bath pipework.
Many thanks
Iain
