We have had a couple of cracked cisterns over the years and the current one was
not fitted too well (by plumber). The overflow pipe has been forced into
position and is getting in the way of some new "boxing-in" which is in progress.

I would like to route the pipe between the wall and the basin waste pipe. Can I
bend 21.5mm plastic pipe to joggle it (hot air gun)?
There is only a 2" offset between the tank connector and the hole in the wall so
not room for just 2 90degree bends (whose legs are about 2" long each).
Alternative would be a bent tank connector to (say) 6" horizontal pipe then bend
to vertical then bend back to the wall hole.

I know that you can get syphons with internal overflows but I prefer to use the
3-piece units which allow easier replacement of the flap diaphragm.

solvent weld connectors are generally shorter, could do a short vertical
drop to a single 45 degree bend, then on to the existing 90 degree
elbow? You'd need to rotate the elbow a bit (or replace it if it's welded)

Must admit, my first thought was HepFlex (about 3/4 down this page
http://www.bes.co.uk/products/125.asp). Unfortunately only available
in 32 and 40 mm - not 21.5 (or close). By the time you step up/down
sizes it would be getting pretty unmanageable but I thought I'd post in
case there is anything similar out there in a more appopriate size.

Hypothyroidism is a seriously debilitating condition with an insidious

Although common it frequently goes undiagnosed.

Might be neater to drill a new hole through the wall above the waste-pipe.

Alternatively, you can get 135 deg solvent weld joints for that kind of
pipe. With that, you could mabe squeeze it behind the other waste pipe.

You might get away with combination of some washing machine waste hose &
other fittings to make a flexible connector.

===================================
You could probably use one of these in conjunction with a T-piece:

Other sizes / patterns are available if you browse the shelves.

Given that trade off I reckon the internal overflow wins hands down in this
example. How often do you change a diaphragm?

OK - gotta thank you chaps as usual for a variety of ideas which I will have a
closer look at.
BTW I hate working on plumbing - hardly looked at the damn thing and got weeping
at the downpipe and a bead of water on the screw of the stop valve...
