Fitting new toilet

[RicHax]

I am replacing my toilet with a new low level one.
Unfortunately the bottom edge of the waste outlet is about 1.5" below the soil pipe in the wall. Although I can use a flexible connector the waste water will have to flow upwards. The only solution I can think of is to put the pan on a plinth. Is this the usual solution to this problem or is there a better way?

Yes this happens a lot,

And unless you can re-run the soil pipe your options are limited.

What is the measurement from the centre of your
new WC outlet to the floor ?

What is the measurement from the centre of your soil
pipe to floor at the wall ?

is the soil pipe PVC, Cast Iron or Lead

Moving the soil pipe or making a plinth are about your only options here, wouldn't advise running the waste uphill

Thanks for the replies. I think I will try a plinth.
jas05 - because the soil pile slopes upwards into the room, both measurements are 7 inches. This suggests chopping off the soil pile at the wall and fitting a new horizontal pipe would work - however, I think a plinth is easier, and doesn't involve potentailly expensive repairs if I get it wrong!
I have discovered another problem. Using a plinth and a connector, when the pan is as far back as it will go the close fitting cistern is more than an inch from the wall. If I remove the connector, however, and plug the toilet waste directly into the spoil pipe (which appears to be a tough rubber pipe,which then opens into a cast iron drum), not only is the cistern against the wall, but the toilet waste fits very snugly. Would there be any problems with this solution? (NB I would seal the pipes together with plumbers mait of course.

I spose technically that would work, it's a bit of a nasty way of doing things though, can't you just cut the soil pipe back a bit?

 

[jas05]

A plinth will look awful,

as Muggles was saying

Cut the pipe flush with the wall and use a straight Multikwik on the wc

and a extension Multikwik to suit the cast 3-1/2" or 4"
( might need to cut this down a bit )

have a bit of faith and go for it, you wont mess up....

... and not worry about an uphill flow?

So youre saying its 7" at the wall and 8-1/2" centre to floor at the wc.

the run on that cast pipe would have suited the old style "P" trap toilet
outlet ( 14 deg.) that were fitted years ago.

cut the cast in the wall from inside the pipe a couple of inches the furher the better using a cheap circular diamond tile saw blade
or worn down metal cutting discs centered on a 12mm bolt with washers and nut horsed up tight fitted on a high speed drill chuck,


this way will keep damage to the wall at a minimum

Keep a firm grip of the drill
