New toilet

[jupiter_19630]

Hi all,
I,m in the process of fitting an upstairs toilet. My only concern is the waste.
I have 2 options. one is to run a soil stack straight down to the mains sewage which obviously involves a lot of digging.
Option 2 is join up to the downstairs loo. This connects to an iternal soil pipe in the floor directly behind the pan.
My idea was to run a soil pipe out through the wall, down the wall and back in through the wall connecting to 2 toilets to the internal soil pipe.
Is this possible? and what connectors would I need?
Thanks.

You should be able to do either but if you connect to the downstairs loo drain you will still have to provide a new vented soil stack & reconnect the loo in to the side of the stack; other wise the first time you flush the new upstairs loo could mean you get a nice pebbledash decoration in the downstairs loo.

Marley used to have a very useful design guide & product list on their web site but the link I have no longer works; a Google search should throw up their new site. Remember that whatever you do must comply with current Building regs. & BC will want to inspect (fee involved) & may even want to witness a pressure test on the new stack/drain. I faced a similar problem with a new en-suite last year &, in the end, decided it was easier to provide a new, separate stack & connection to the foul drain.

Thanks for your reply. I,ll have a look see if I can find the design plans on Marley you mentioned.
Dont relish the idea of digging down to join the mains but looks like I might have to now that you point out the problem of pebbledashing downstairs. Fitting a stack to connect the downstairs loo to could be a problem. Toilet currently discharges straight through the floor directly behind the pan and space is very limited due to it being a small cloak room.
