Linear drainage question

[markbryant]

Hi

I'm about to begin re-doing my patio. Unfortunately, the land slopes towards the house - I don't think there's anyway I can avoid this as it's quite an incline.

So I've decided to install a linear drainage system between the house itself and the patio. There's an existing drain at the moment with I can drop into - this also has a pipe from the kitchen leading into in from the sink etc.

Is it okay to remove the existing drain, fit the new linear one then just cut a hole in the top to allow the kitchen pipe to slot in?

Also, I'm looking at buying an ACO Hex Drain - will this be okay? And am I correct in reading that this should be placed on a 50mm bed of concrete (C20 mix). With the top 150 mm below the damp course?

Sorry, if I sound a bit dumb but I'm a patio virgin - bit gentle!

Thanks in advance,
Mark

no mate its not ,your kitchen waste goes to a foul run,if you start draining surface water into it it can flood the sewers,also you will get eau de poo on your patio
you need to find a rainwater pipe and connect into that drain,or doing it properly construct a soakaway

all drains now should be trapped to avoid deitrius getting into the runs

any more questions ask away

Thanks for that LLL!

I'm a bit stumped now as the rainwater pipe is at the side of the house (in my neighbours garden!) he's just block paved that area of his garden so unfortunately that's a no go.

I've uploaded some photos to give you an idea of the situation here...

You can see how the current patio (by the previous owners) slopes towards the house, and the rest of the garden is raised.

Also, doesn't a soakaway need to be 5 meters away from any building?

Any ideas? I'm open to suggestions!

Thanks again,
Mark

well in the official world you should dig a soakaway in that lovely green lawn of yours

of course if you ran a linear drain via a trapped gully (no smells remember) in the foul waste run,it would save all that digging and mess,
but i couldnt possibly recommend that :;):

Thanks again LLL!

Yeah, I don't really fancy digging up the lawn! Haha...

I've put up a diagram on that page now to illustrate how I saw things working initially...

There's a gully in place at the moment to drain surface water so I thought this arrangement wouldn't be too different? But it would look much neater.

Sorry again if this sounds a bit dumb.

Cheers,

I've been looking at this again, and was wondering if the linear drain is necessary at all?

We've established that the patio slopes towards the house, would it be okay for the new patio to still do this, but also just slope towards the existing drain? Making a funnel effect?

Baring in mind there haven't been any issues with the previous owners arrangement.

Many thanks,
Mark

I've just done something remarkably similar with hexdrain.



Although not ideal in your case you can run surface water into the foul drain. Just trap like LLL says. In my case it made no difference as I had a combined system.

I doubt you'll be able to 'channel' the patio water into the hopper.
