extending soil pipe

never_enough

I am replacing the bathroom in my 1920s house & found that the original toilet ciston is larger than many modern ones. This means that the soil pipe (for s trap toilet) is too far forward. I was wondering can the soil pipe under the floorboards be extended (only needs to be about 6") or would the whole length (right across house under boards) need to be replaced as one piece? Is it possible for a competant diyer to do, or should I get a plumber to do it? I could box in behind the ciston to bring that forward but think it might look pants!
If it were possible to extend the pipe it would also mean that I could go for a close coupled toilet rather than low level one, which would be great as they sit lower than current one & that ciston is partly over a window.

Or I could extend the pipe that goes from the ciston to the back of the toilet pan, but not sure on the angle etc...

Hi

I assume your bathroom is up stairs?
If so then its likely that the waste goes out through the wall behind the toilet. Have a look outside Is it cast iron pipe?
If yes then it will be quite an involved job cutting back the pipe under the floor.
One of these might look good in a 1920's house. The flush pipe can be cut to make it lower. So unless you have a very low window sill it should work.http://www.bathstore.com/files/PRODUCT_GROUP/196/THUMB.jpg
That's bathstore.com by the way.
Good luck

can you not fit a p type pan and use a plastic rubber connector?

the connectors are about 5 to 15 quid.

Thanks for your help! :A
The bathroom is upstairs, but the soil pipe doesn't go out the wall in the bathroom, it goes under the bathroom floor, under the landing & out of the wall on the other side of the house(so in opposite direction to the toilet).
Hope you understand?! It is a cast iron soil downpipe. So what I need is to make the soil pipe longer under the floor to move it closer to the wall. Is it possible to join bits of soil pipe under floorboards or would it need to be taken back to the outside soil pipe & installed as one long bit?
That's the toilet I want-Savoy Edwardian. I spoke to the guy from the shop & he said that as the distance from the wall to the back of the soil pipe is approx 19cm that it wouldn't fit. The pipe that comes with it isn't long enough apparently. It's approx 24cm from the wall to the middle of the soil pipe. The window starts only 57cm from the floor. I'm not too worried about a corner of the window being covered, it is at the moment, I just want to make sure the new toilet will fit! And look lovely

I'm not quite sure how that would help Can you explain s-l-o-w-l-y

I think that would bring the toilet further into the room which I can't do due to health & safety for the purposes of cat swinging! ;0))

Yes you can extend the soil pipe under the floor, look in Yellow pages at look for Draincenter (part of the Plumbcenter group) but deals in drainage only.

You need a Timesaver coupling(castiron clamp-2 part) this will allow you to join 110mm plastic soil pipe to the cast-iron.
Cut back the cast-iron soil pipe(use a Grinder) then fit the clamp then attach the plastic soil, then fit any length of pipe or bend you req.

Would this Multikwik MKBAR90 connector (or similar) be of help?
