Hi,
I am looking to install a 2nd bathroom upstairs into my new house (new to me, built 1985) so have been examining my current set-up.
To me the soil stack seems a little odd and am not sure if i can connect into it safely. I think it may have been set-up like this so that the soil stack would not run on the outside of the house and the vent would go through the roof at the back of the house.
I've drawn a diagram to explain it better, but basically i can see the partially covered soil stack in the corner of the airing cupboard in the downstairs bathroom, i've estimated that the soil stack appears under the middle of the bedroom above's floor, so takes a 90 turn, under the floor to the eaves, then I can see it take another 90 turn up and out through the roof.
What I don't know is what it does under the downstairs bathroom floor as the floor is fully tiled (onto suspended timber floor)
Is it safe to assume that the section under the bathroom floor will have the required falls.
Assumming i can make a connection to the soil pipe under the 1st floor bedroom floor, but below the level of the side that leads to the vent so the waste doesn't collect in that pipe, is this legal?
And I take it that it's ok to send shower and sink waste down the soil pipe?
I can guess that the answer is going to be pull up the bathroom floor for a look, but it will be interesting to see if anyone has seen an arrangement like this.
