    HI,

    So we have a build over the agreement and the building officer came, he said we have to replace the channel with clay pipe only not plastic.

    (I have found, not sure if that is the right one)
    https://www.travisperkins.co.uk/Hepworth-SuperSleve-HouseDrain-Pipe-100mm-x-1600mm-SP1/p/711543

    I asked him do we call the water board to come and do the work (as it serves about 5 other properties) or do our builders do it. He said your builders can do it.

    I then asked how to we couple it to the old clay pipe (which is like really old and half encased in cement), can we use those rubber couplers with jubilee clips (They allow for different diameters) I said - he said no. I Think he said to use some sort of clay couplers with quick drying cement - but I cant seem to see them - I only see the flexseal couplers

    https://www.travisperkins.co.uk/Flexseal-Standard-Coupling-100-115mm-SC115/p/221468

    Any help appreciated

    I don't know the answer hereh, but thisere, should all have been submitted as part of your build over application and agreed with the water company before hand. What did you tell them you would do?
    We had to give full drawing to Thames water before we could get the agreement.

    thanks for the reply John. that part was not detailed.

    just the new building superimposed over the old pipes and our proposed redirection of other pipes and position of new manhole. a cross-section of how we would deal with pipes crossing the new foundation (Granular bedding/polystyrene/lintels).

    but no actual details of how to couple new clay pipes to old clay pipes. (private drains will be done in plastic, no problem there).

    no info from thames water about coupling - only pipe must withstand jetting (4000psi).

    Fernco jubilee type couplers are fine. Tell you BCO to do one.

    thanks for the reply noseall

    I suspected as much - I asked him twice about the rubber couplers with jubilee clips and both times he was very sure that I could not use them. I had tried to research it before he came, and all i could find were these jubilee couplers.

    Thames water is coming anyway as the builders damaged the pipe but did not sever it, so it's not an emergency - we will see what they say.

    There were/are some wierd water companies that insist on clay to clay. Ours is Severn Trent who didn’t.

    Rubber coupling will be fine, use the ones which the large stainless band in the middle too to align the joint and keep it there.

    thanks for the reply mfarrow,

    I don't want to go against what the BO said (unless thames water says it ok) - the problem is how do I do it all in clay? I cant seem to find a suitable coupler. Does anyone have a link?

    And there's the added problem of doing the thing without getting a step in the pipe.

    How very stupid. There are plastic couplings (supersleeve brand) that will join clay to clay but they are rubbish. They aren’t tight enough to stop roots getting in.

    Have a look in Travis, there are loads of different bandseals, the plastic end of the AC6000 should fit over supersleeve. I hate supersleeve, it’s like glass, if I were Thames Water i’d rather have plastic.

    Perhaps your BCO is as old as me and remembers stoneware salt glazed double sockets, and drainlayers cutting the pipes on the sand pile, loaded with sand and tapping round+round with a cold chisel and hammer;)
