    I’m looking to need to run a soil pipe through a house wall below ground level and going the route of rocker pipes to allow for any movement.

    For clarity on the situation a soil pipe will exit through a core drilled hole in a house wall and be fixed rigidly in the wall. Internally the pipe will be fixed in free space to the bottom of a suspended timber floor which is attached to the wall, so no movement joint would be needed. Externally the pipe is emerging below ground level and I was looking to make a rocker pipe arrangement to connect into an inspection chamber to allow for any ground/building movement.

    Having never put in rocker pipes before I was wondering if joints are simply made by cutting the pipe into sections and using those rubber connectors with big jubilee clips to create joints that can flex a bit? Am i missing anything or is it that simple?

    Any help appreciated.

    What material are you using for the pipework? Plastic will absorb any slight movement, and even clayware in that situation should have a flexible joint near enough to absorb any movement.

    To be honest, I've never known rockers used anywhere other than on clay or concrete pipes, where they are entering/leaving a large lump of masonry, e.g. a manhole or headwall.

    Would be doing it in plastic. To be honest I would see it as overkill, but technicaly it should be done, so was wondering how it was done correctly.

    Going to ring building inspector tomorrow and will see what they recon. Quite a good chance they will say dont worry about it, but best be prepared.

    My plan for a loo under the stairs has now snowballed into removing structural wall, adding some bifold doors, and a new kitchen... so have a few to discuss! :LOL:

    Virtually every house will have a soil pipe exiting through the wall. Really, it should be lintelled over at that level, so none of the weight of the brickwork above bears onto the pipe, then the hole plugged as required.

    I was hoping to avoid having to carve out a big hole and put in a lintel (much less effort to core drill), and part H gives the use of rocker pipes as an alternative for a pipe fixed in the wall.

    Waiting for a call back from building inspectors and will find out what they think, hopefuly they will just say stick it through the wall! :)

    If they insist on a lintel, you could still core drill out the hole. Choose position for pipe exit, knock out course of bricks above, replace with lintel. Once lintel is set in position, core drill out your hole underneath. ;)

    Building inspector got back to me and his view was the house would of settled as much as it was going to and just coredrilling and running pipe straight out would be fine. :)
