1970's ex. council house. Bathroom is entirely inside, with no exterior
walls. Have just revealed some hidden pipework to find that the existing WC
has an overflow that runs under the bath and emerges in a cupboard in the
adjacent bedroom. Fortunately there has never been a problem.

I am about to replace said WC. What is the best way to plumb this given
that there is no easy access to an outside wall? Best I have found so far
is a tundish and presumably a U bend into the soil pipe. New WC has
already been purchased as part of a suite so there is no option of
replacing with a WC that will overflow down the pan.

I've seen cistern overfows arranged to discharge over the bath.in
similar circumstances. Not very pretty, but you do get a visual warning
of a fault.

It's a possibility but perhaps I should have said - it is separate
bathroom and toilet. But they are next door so I might be able to route it
through the adjoining wall. But as you say, not very pretty.

Modern cisterns now have internal overflow, as they do on the continent.
makes fitting them much easier. no big holes to drill throught the wall. etc

except for the even bigger hole to let the turds exit?

I noticed in an office building that the overflow pipe was taken down and
into the toilet pan, The end was flattened to enter below the seat. This
gave a letterbox shaped outlet which may have restricted the flow a bit but
certainly gave warning of impending problems. One other thought. I don't
know how the overflows work that run into the pan, but it seems logical that
it is all contained in the syphon unit, so perhaps you might be able to just
substitute a replacement syphon.

I hadn't thought that it might be a function of the syphon and not the WC.
I shall take a look this evening if I get a chance.

Mine is integral to the siphon - I have checked! (Same problem, ladlocked
bog). The bloke in Bath Store said it was a fairly common feature these days
- as I made a point of asking before I bought.

Pah; teenagers and their magazines.

If the new cistern doesn't already have one then replace the flush
mechanism with one with an internal overflow, e.g. Screwfix 20824
http://www.screwfix.com/p/opella-dual-flush-siphon/20824 if it's a
siphon type with a lever, or a variflush
http://www.opella.co.uk/flushingvalves-3.html if it's the drop valve
type with a pushbutton.

Thanks. That looks ideal if it does not already have one - and cheaper and
more aesthetically pleasing than a tundish.

The power of Usenet strikes again.

You don't have to change the WC, just the flush mechanism. These are OK
http://www.fluidmasteruk.com/product/550073.aspx B&Q stock them.

As others have said, a new toilet is likely to have an internal
overflow. But if you really did have to solve this problem, then you
might like to consider a one-way valve instead of a U-bend (trap). For
a start, you'd have to fill a trap with water at installation time.
Then, under ideal circumstances, the cistern will never overflow and the
trap might dry out (or contain nasty stagnant water). McAlpine (at
least) make a combined one-way valve and tundish-equivalent for this
purpose.
