Soil pipe connetion question

[jgw1]

Hi all,

DIYer doing up his bathroom. I have tiled my bathroom floor and grouted this evening. Used 12mm ply and the tiles plus adhesive were 12mm.

So when I planned the soil pipe I bought a piece to raise the soil pipe 10mm (McAlpine) and a regular 90 degree bend (Floplast). These are in at the moment.

See pic:

HOWEVER, the join between the two pieces (the black ring in the pic) is very sturdy - no probs there. But the join between the raising piece and the old soil pipe (just after the collar in the pic) is prety flexible. I am a bit worried that this is a problem.

This is primarily because for the pan connector to be fitted it still needs to be raised around two centimeters - so doing this will place a little stress on this joint. Stress that I am worried will cause the joint to leak.

So basically is it usual for these joints to have a little movement and can they take a little stress. Are there alternatives to what I am trying to do.

Any advice greatly recieved as I am planning on fitting the loo tomorrow so that I can stop visiting my local pub.

you could use a flexi pan connector

Providing the fitting you have going into the old soil pipe is the correct type and size then generally there is a fair bit of leeway as regards movement. Trial fit just the pan (without the cistern) and see how it all looks, then you can chuck a few buckets of water down the pan and check for leaks before you fit it all permanently.

Another thought, if it does leak then you could cut the old soil pipe down a bit ( getting rid of the collar) and then connect a length of plastic pipe using a rubber "fernco" type coupling, that will give you plenty of movement.
