WC to far from soil pipe?

[poppyfields]

I am having a new bathroom fitted and ordered a back to wall WC with fitted bathroom furniture. The plumber has now informed me that because we have moved the WC further from the soil pipe, we have to put the WC on a plinth to create a slope! this is a problem because of space. We have the option of Saniflow pumps, but these are supposed to be horrendous and expensive. Can I lower the soil pipe, which is currently exposed within the bathroom? Can anyone help?

It is probably impractical to lower the entire soil pipe, but you may have enough space to cut out the existing 'Y' piece and fit a new one lower down.
Why is putting the WC pan on a plinth a problem? It should only take up vertical space. Unless you have very young children, (or are short in the leg) raising the WC by a few inches could be the simplest (read cheapest) solution.

If it is a bathroom that is not on a grond floor then I can not see a problem. You're plumber should quite easily be able to adapt or replace the existing soil pipe with no problems. I suspect he did not do his homework and did not foresee this work when he measured up and surveyed the site to see what work was involved, and subsequently has not quoted you for this extra work of knocking holes in the outside walls to lower the pipe and is now trying to fob you off with the cheapest soloution of sitting the pan on a box plinth to allow a suitable fall to the existing ( un-altered )soil pipe.
But then again if the bathroom is on the ground floor then he may be unable to alter the soil pipe and the only way round this is what he has suggested or the mecerator option which you apear to be against due to the excessive cost of the units. ( Saniflow is just one make of these macerators ).
They do however work perfectly fine when installed correctley, but i would not recommend one for the main bathroom as they are noisey
and would only reccomend one for an additional cloakroom in the cellar, Understair cupboard space or attick conversion when it is impossible to gain access to the main soil pipe.

gasman is correct, its not impossible to move the pipe to suite, its just more work. It looks like your plumber dousn't want to do the awkward part of the job, just the easy bit. This is a problem with a lot of tradesamen(not all)they want the big money without the hassle.Get someone else.

A simple but costly way around your problem is to fit a "SANIFLOW" unit at the back of your loo, this chops everything up and sends it down a 2" pipe under pressure so elimanates the need for a fall, run this into your existing stack and connect using a saddle strap connector. The down side is you will need to supply the unit with 240 volts via a fused spur.
The plinth idea sounds the cheapest.

Trouble with sanflows is they are noisy and can quite easily be jammed if anything other than the norm is put down the loo, which does happen sometimes. Also not much use in a power cut.
