Reducing Soil Pipe

[bighen]

You can not always use a durgo

All houses must have at least one vent to atmosphere, if his property is a one stack house then he must not use a durgo

Not quite true.

You work on a 1 in 3 principle. ie. every 3rd house must vent to atmosphere. the other 2 can utilize air admittance valves.

Knew my years in management would come in useful eventually:lol:

Different councils, different rules

When i have dealt with Edinburgh building control they have insisted on this

I would always prefer to vent to atmos, We had issues in a large developent of new flats where the durgos had been badly fitted, it was only when we tested that we found out the valves where not correctly seated

Scotland has a totally different set of rules to England.

Roof bracing/covering technique due to stronger winds
Plaster thickness - 5mm min
etc

But the NHBC stipulate the 1 in 3 rule to which all the councils in England I have dealt with accept

I am with bighen on this one. 1 in 3 vent to atmosphere, i only use AAV (dergo) when i have moved a w/c or extended the branch run into the SVP beyond 1.5m of the vent pipe.

I think that is the regulation.correct me if i am rusty on that reg.

Im only moving the toilet location from 1m away from the stack on one wall to 1.5m away on another wall not going to be altering any vents just the soil pipe route

but concerning the stud work,

should I remove the old dot and dab plasterboard before attaching the stad or can/should I just stud over it ?

If it were me I would start from scratch.

Thats what I did when I rebuilt the studwork and changed the soil stack for this loo.

The soil stack was laid out first.
The stud wall was rebuilt to conceal it.
To reclaim lost space, niches were cut into the wall above the soil stack for storage.
The whole area was neatly tiles to conceal all pipework.
