Hello.
We woke up in a VERY smelly house this morning. We'd been getting the odd pungent whiff here and there ever since we'd taken the dining room ceiling down to assess the condition of/replace some joists. ( - the internal waste stack runs through the dining room).
After checking that the noxious odour wasn't the result of my Wife's morning oblutions, I checked the waste connections on all the sanitory appliances and found no issues. I checked that all the traps were still sealed, and they were. After that, I started to look at the stack and noticed that it is of the Marley push fit variety, and now being almost 50 years old, it looks like some of the joins in the the stack are leaking with evidence of seepage.
All of the waste pipes look to be connected by push fit too.
I'm contemplating DIY replacement - at the moment it is not an issue to bash out the plaster covering the stack (precautions taken for asbestos) and with the right access equipment, get onto the roof and remove/replace the stack top vent. Our home is a typical 70s built 2-story suburban dwelling.
My only concern is that the bottom piece of the stack with it's long radius bend is embedded in conrete turning a relatively straight forward job into a complicated one, if I were to attempt it myself. There is a push fit connection at ground level. I'm figuring if I use PVC pipe with solvent welded joints to replace all of the stack above ground, I could leave existing bottom piece in situ, perhaps replacing the O ring?
Am I clinically insane for even considering this? I would of course consult Part G of the building regulations before starting any work.
Thanks in advance for your help.
