Hello again,
Installing toilet in loft conversion, house has two upstairs toilets with internal soil stacks, these are vented into the loft with aav's.
I'm guessing the vent pipe are 3"', these are installed in box sections in the bathrooms.
I'm thinking my only option is to replace the 3" pipe with a 4" and extend the pipe up into the loft for the toilet, sink and shower. Then vent the pipe further up.
Which will mean dismantling the bathroom.
Can it be done like this?
Only other option is a saniflow.
