110mm bend radius

[Mr Blobby]

A bunch of these have arrived on site to go into the KORE slab for services (like 32mm water pipe into property) as well as waste out:

 

 

 

 

 

Should these be long radius bends instead so that it is easier to pull services through? 

Do they need to be like the above so that the pipe runs vertically through the slab?

 

Am I over-thinking this?

That should be fine for getting any of the services into the house but a long radius bend would of course make it slightly easier, especially for the water. 
 

We did have a struggle getting the BT cable to the vicinity of the house. It came down a pole and into BT ducting which was about 25m long and included 3 ninety degree bends before it got to the entry to the house. That thin cable in a long narrow duct with the three bends was a bitch to pull through.

we don't seem to do long radius bend round these parts.

Diagram 2.1 says large rad bend should be used at bottom of stacks. Same diagram as in English regs I think.

silicone grease on the cable is your friend here .. stops it snagging and doesn’t affect the insulation

@PeterW  way too late for me but hopefully that nugget of info will save someone else the almighty tug-o-war that we had!
