    My grandmothers house is approx 100 years old the guys that did the cobble lock told her the sewer pipes were (clay pipes) ! I have never heard of them. The problem is she keeps getting blockages and a plumber told her she needs an AJ as the length of pipe is too long to "rod" the pipes. Money is tight for her and I said I would have a go at it, I have done a little with wavin pipes 4" and would be happy enough if these would just slip into the "clay" pipes. Any tips or advice would be appreciated also any tips on how to lift cobble lock without breaking it. Thanks.

    Is the clay 6" or 4" do you know ? Is that the correct term ?
    Thanks

    Last Christmas I had to replace an old clay shore with a new plastic one. I used one of the couplers with jublie clips on either side to join the new 4" plastic pipe to the clay pipe. The interior diameter of both pipes is similar but the clay pipe has a much thicker wall. So if the plastic pipe is 4" the outer diameter of the clay pipe is close to 5"

    I bought the 4" plastic to clay coupler in goodwins in blanchardstown, but i've seen them cheaper in woodies since then, about €13.

    The trick is cutting the clay pipe some what square so the coupler will just slip over it. The clay pipes are very brittle, especially as they are so old. I cut most of the way through my one with a 9" grinder. So most of the pipe came away nicely. The bit that was left I cleaned up with the 4" grinder.

    To be honest you can't really go too far wrong, the plastic pipe is very easy to work with and the coupler to join the two pipes is as simple as it gets.

    I've attached pictures of the clay pipe after i cut it and the coupler in place ready for the feed from my new shore/u-bend

    You could always dig down and build your own manhole using galco 24x24 lid.
