PVC 110 TO SQUARE CLAY CONNECTION ISSUE

[anthony]

Hi all, forgive me if my terminology is incorrect.

I need to connect a new aco drain to an existing rainwater drain. This is made up of a clay 'yard gulley' which has a square clay 'extender' (not sure if this is the correct term) on top which the down pipe drains into. (see photos 1&2)

 

I want to remove this 'extender' and fit a new pvc hopper in its place which also has an outlet for the aco to drain into (see photo 3) however the clay yard gulley is square and the pvc fittings are 110 circular and I can't find a square clay to 110 pvc adaptor?

 

Can someone provide a link to one of these adaptors or advise me if this is the right or wrong way to go about it please?

Many thanks

As you have it and secure with concrete unless you need to keep it accessible but I can’t think of any reason why.

put a longth of pipe into the hopper as far down as it will go then foam it in to hold it. fill top with conc.

If that indicates the height you are going to raise the ground level to, check you are not too close or even above the Damp Proof Course first.
