Perforated land drain to solid pipe - Connection

[steve seymour]

Hi guys

I'm about to start a herringbone drain project on my boggy clay lawn. I found a solid drain pipe at the bottom of my garden which connects to a surface grate flush with my lawn . The pipe begins in my garden then runs straight to next doors garden and so on. I'd like to run perforated pipes to it. Question is how do I connect to it? I was going to use a adaptive coupling from Flex seal and join the two pipes directly but I'm now thinking that this won't work as the perforated pipe doesn't carry the water like a solid pipe.

Hope this makes sense. Thanks for help in advance

Think I've solved it. I'm going to perforate the solid pipe as it's easy to drill into. This way all I've got to do is end my main drain in the area of the carry away pipe and the water should find it's way in.

Nahh just join them up, dont worry about if the pipe is carrying anything, chances are that if your land needs this drainage then its slow to pass through anywhere so let it find a direct route out to that pipe, no need to drill it etc. its just as easy and the correct way

Thanks for the advice. I'm all set to go and order every thing

How old is your house? Are you on a foul or combined system?

If its the foul drain then you can't connect your drains into into, it will have to go into the top water drains where your downspouts go.

Not to mention the trouble you could get from the local water authority, you need theur permission to combine them. but you are creating a leach field for those foul drains if they ever back up you'll have a garden full of sewage

hi
I've done lots of checking with waterboard and council regarding this pipe. The pipe isn't a sewer/foul drain. The pipe isn't registered with the water board or local authority. Council believe it was put in to drain the land while the houses were being built. All I know is it works as I ran a hose pipe down it for around 15 mins and it went somewhere without backing up
