Whats best way to make this new foul connection to existing? I want to come in line with the trench as pictured. I can put a couple of slow bends before going into IC or a slow bend after coming in to discharge in direction of flow. Obviously a flush connection would involve either cutting a branch in or cutting new pipe quite low down on invert of existing. I thought because I'm coming in on the angle best to keep an inch or so up off existing invert?

Would be doing all pipework inside IC with clay and use a flex seal to plastic once through wall act as a rocker.

Existing joints could do with bit of gear in as you can see

Open to advice please

Cheers

hi Jwill
assuming that the flow is the same way  you need to break through the IC at invert level and create  a New slipper and rebench the IC,we used to be able to get clay slippers but hard to find now,so we generally  cut  sweeping bends to achieve this

Yes flow is the right direction. Have a couple of bends could cut into slippers. Would flush invert be ok with it joining on a bend like that?
Part of me says rip the lot out and replace with pvc. Some of the joints already look a bit gash

always a danger ripping out the lot as the old hepsleeve is liable to fracture
personally i would gut a new slipper on to the bend
and what do you use to post pictures mate?
I can find nothing that works

Tell me about it RE the pictures. Hence the thread title I got in a bit of a mess! Only one this site seems to like is "tiny pic". Its ok no registration needed but only one pic at a time.
Been out there this morning think i've got a good plan now. Will give me flush invert and get rid of existing bad joint. Think I will now go with a channel 45 Branch cut into existing. I offered a pvc branch in as I had it to hand, seemed to look about right with the angles.

What do you think?

hard to explain it but you could almost cut a straight length of pipe at an angle at the end ,and just cut 45 % off the top for rodding access
I feel the bottom of that Y will be hard to get right if that makes sense?

Hi Boss, just got it done today. Also re benched the one further downstream with grano to keep all you lot happy.
I used the way I planned in the end. Keep that new invert nice and low as its only 600mm from top of paving at minute and I've got to get it to the new build and under slab. Should have plenty on a 1:80
Also got rid of a nasty lip where the old bend finished
