Hi. I need to connect two old land drains to a new land drain pipe. The old drains are D shaped clay pipe. I was going to use an inspection chamber with rocker pipes. How can I connect the old clay pipes? I assume that an adjustable coupling won't fit. Pipes all sit at 90 degrees to each other. One old pipe faces north and a different size faces west, new pipe will face East. (Couldn't think of any other way to describe positions.... ). New to this field so learning as I go along! Many thanks.

When you say D shape, do you mean a horse shoe pipe. Either way, either cut a hole in new drain and butt it up and seal best you can and cover with gravel. Or get a plastic. Joint for new drain and fit best you can. Can you get a picture on here so someone with more knowledge than me can coment

Hi. I'll take some photos tomorrow. The pipe has a flat section which sits on the ground then rounded on the other sides like a normal pipe. It's a Tricky situation as this drain runs along the back of my house, about 2 feet out. It would be best to have a good seal as the water will drain from the new pipe towards the old pipe. (The new pipe is replacing old pipe which had broken the surface of the path and top of the pipes were broken.)
Thanks for your help.

The horse shoe pipe has no bottom bit. They might be just local to me, South cheshire
Can you get the new pipe inside the old pipe.

Hi. The new flexible pipe is too big to go into the old pipe. The joint is currently the u bend of an old toilet whith holes chipped out.
I will try to upload photos but looks difficult as I don't know where on the net to put them! Any advice welcome

You have to load pictures on photobocket or the like. Sounds like the old toilet needs breaking out.

Could you use some reducers with above ground fittings and go to smaller section pipe on your connection. The send these into old pipe and seal? Or would these be no good underground?

Could be a land drain in Herringbone design, or maybe a peach field from a septic tank. Is there an old tank in the area tank ?

I think that the photos are successfully put up on photobucket link above. The old toilet "joint" butts against the soil pipe, you can see it in the first photo. The soil pipe also crosses the trench at the corner, you can see the concrete cover in the corner of the wall in the second and third pictures. So I can't dig the trench any deeper.
I am a total novice in terms of drains, so I'm learning as I go along. Need to sort this problem as the hill behind sheds water down to the house, comes through the stone wall as well as following the left hand land drain into toilet joint (in the pics) and making the house damp!
Thanks for all your help.
