Hi all
I’m now a proud owner and was just wondering if anyone has removed soil pipe from bathroom and kitchen and have run it outside to create space. And also is there any asbestos in the outhouse ceiling I also believe there may be some behind the baxi boiler is this true and is there any more I should worry about ?
Thanks hurdey 🙂

This is the whole stack and vent exposed, the asbestos starts where the old copper pipe to the toilet cistern crosses it. We’ve cut the cast iron off at the first collar above the rodding access.

Here’s the bathroom now, not finished but you can see the vent pipe has gone, and the built-in cabinets. I’ve covered the window wall with zebrawood splashpanel as a feature and am tiling the other walls.

Hi Hurdey,

I’ve gone for a compromise and removed the boxed in vent (stench) pipe in the bathroom and replaced it with an air admittance valve but left the soil pipe in the kitchen. It makes a big difference in the bathroom having it gone but I’m not really bothered about it in the kitchen, plus I think external pipework is pretty unsightly.

I found that the cast iron ends just above where the handbasin waste enters the stack and from there on up to the roof vent there is a single asbestos pipe, about 8 foot long. Our original plan was to prize out the top cast iron section, but it was so well stuck in that this was not possible so had to cut it off with an angle grinder instead. I have taken the handbasin waste down to the bath waste pipe, which enters the stack between the ceiling and floor level and put an air admittance valve into the cut off top. Also the condensate pipe from the new boiler goes in here, so it cannot freeze outside. This is all concealed by some built-in bathroom cabinets.

Obviously you need to be careful removing the asbestos pipe as it is too long too take out in one piece, so you need to take suitable precautions when cutting it.

Hi again Hurdey, as itsrabbit has stated it is pretty easy to remove the soil pipe from inside the house and replace it with a new plastic exterior pipe.

The main pipe itself is cast iron and can be pretty easily smashed as itsrabbit has stated. There is sometimes a small amount of asbestos at the very top of the pipe in the loft space, This is the main vent that should exit through the roof covering. This is low grade or low risk asbestos where it is present and should be dampened and wrapped and sealed with polythene before removal, trying not to break this section up.

As for the back of the Baxi back boiler, I have removed around six of these to date and at no time have a found asbestos at the back or surrounding the boiler. That’s not to say there isn’t any because different builders used slightly different materials when they were constructed.

My advice as always would be to wear a disposable boiler suit and a good fine particle face mask during any removal of this sort and ensure the area remains damp by using a simple water spray bottle just to be on the safe side.

Always ensure any suspicious material is bagged and sealed. You may find that your local council has a free collection service that will safely dispose of any suspicious waste. You will probably find that there isn’t any asbestos behind the fire but it’s always best to remain cautious. You will also find that the chimney flue is surrounded by grey lagging wrapped with wire mesh. Again, in most cases we do not beleive this to be asbestos, but follow the same precautions and keep it moist, etc. It’s also a good idea to tape dust sheets over doors because it can be a bit messy.

Also remember that there’s a lot of weight in the cast iron flue, but if you follow the guide here, written by Doug, you should be fine. http://bisfhouse.com/removal-of-bisf-house-cast-iron-flue-tube-by-doug/

I have removed soil pipe to out side.
in the kitchen smash all of the pipe and take it below floor level and then seal it over
on the out side dig down and pull the pipe of the pipe going into the house then seal that over .
then put in new pipe out side our join up pipe that goes to sewer pipe.
then from out side pipe you can put up the straight pipe that gose up wall.
then put new pipe work straight threw the metal wall fit bend and join to pipe.
from all out lets bath etc go straight threw metal wall then put a bend to couple up with down pipe
Do not forget to seal over the pipe that is left stuck out of the roof.
