Drainage connection to threshold drains

[Pisces67]

Hi can someone tell me the best way to connect two threshold ACO015 threshold drain to an existing clay gully pot. The drains will do either side of the pot close to the wall. Would it require removal and using plastic fittings? Looking down the gully it appears there might be three sections.
Thanks

You will have to dig down and replace the pot chamber for the aco one or you will have to run a new drain to each depending on where you want the acos

I'm trying to use the existing gully position, which currently takes rainwater into the manhole. I'm assuming there is a clay bottle trap at the bottom as per the photo (water visible). I need some at sort of adaptation which will allow me to modify the clay gully to take the threshold Drains on either side if the gully.
Is it possible to dig down to the 3rd section (trap) and place a rubber coupler 163mm to 110mm and stick a hopper on top which has two opposite inlets for the two channels drains either side.

Nope looks like you will need to connect into the main drainage

Would the follwing be correct:
Remove clay pot and p trap and replace with plastic p trap. Insert plastic pipe to finished level and place ACO outlet. See pics?
In effect completely remove the gully feature and have ACO drain running continously through with rain water down pipe over grate.
Correct?

That’s correct dig down and replace the gully /pot

Just a thought, before going ahead and digging and disturbing the existing gully, can I take the clay collar off and then insert plastic pipe into the gully which will then alow the underside knockout if the aco drain to sit on top of level with the final paving.

You could do depending on your finial height and it’s the correct dia

You could just put the aco outlet above the gully, it doesn’t need to be joined to it as such.

That's one option, but I assume the clay pot would still be visible?
I have had two quotes for my drive and each quote mentions a p trap as part of the threshold drains that we are discussing. Not quite sure how the p trap would be introduced, I can only assume it means digging out the old one, any ideas?

Sounds like it’s not your problem, let them get on with it.

 

[Pisces67]

It's my job diy, with help from others, just trying to get ahead of the game and plan materials etc

 

[Ben-gee]

I thought you had quotes , my mistake.

 

[Pisces67]

I did but I don't think they paid much attention to the drainage detail only surface observstions

Let them get in with it, they’ll have overcome worse in the past!
