32mm Waste Pipe - Slight Misalignment

[self builder 123]

Hi

I am going to fit a semi pedestals underneath a wash and basin.

The 32mm waste pipe comes through the wall horizontally.

When the trap is fitted the telescopic adaptor needs to be at the minimum position to allow the semi pedestal to fit over the bottom of the bottle trap.

The wash hand basin has a pop up waste.

There is a slight misalignment ( 10mm to 15mm vertically ) between the 32mm pipe and the inlet to the bottle trap. In order to get it to fit I had to bend the 32mm pipe up and into the trap inlet, but I am not happy with this.

I can not get to the pipe in the wall to adjust the height as it is fully tiled.

The misalignment is so small that I can not make use of 45 deg elbows.

Any suggests how I might overcome this ? I have read about flexible adaptors ?

Many thanks.

Classic case of pottery makers not considering carefully what needed to be covered by their artistic creations!

Don't suppose THREE 45s (2 of the M&F type) would fit it, with the trap rotated slightly?? (With three bends, you can set different angles...)

fit one of these.
Adjustable from o to 90%.

well posted, Bob....but it`s from 180 to 90

If 2 x 45 is too much then buy 2 x 112

Hi

Who manufacture the 112 deg fittings in 32mm which you mentioned in an earlier thread ?

Cheers

Heat the pipe and bend it.

Heat a wide area all around the pipe and gently bend it to suit. You need a blowlamp with a large flame and I also use a welding gaunlet. A heatgun would probably work better. Keep the blowlamp moving all the time around the pipe and go slowly - its easy to go too far and melt/kink the pipe.

May be worth practicing on a bit of spare pipe.

If there's an obstacle, then remove the obstacle.

mount the basin 10-15mm lower!

RT(f)OP!!
The problem is that the combined height of trap + popup waste is only just covered by the half-ped. So the (telescopic) trap can't be moved DOWN and the outlet from it can't be moved UP (to match the pipe in the wall) because of the height of the popup waste. And moving the trap DOWN wouldn't improve the situation anyway.

OP - please confirm we're not all misunderstanding the problem!!

Why not enlarge the hole in the wall so you can align the pipe properly.

Thats really your only option if you can't reposition the basin.

CroydonCorgi - I did not say "move the trap down" I said mount the basin lower.

This moves everything down except the pipe the OP is connecting to so it all lines up neatly.

Actually they call it a 165 deg.

I think if the OP is concerned about tiling around the waste pipe, the position (height) of the basin is pretty-much already 'cast in stone'.
