Not quite, in the middle of a run between inspection chambers. As in inspection chamber > 2m straight > 45 degree bend > 2m straight > inspection chamber. I think tomfe has the correct answer. Thanks for all the help.

Can i use a 45 degree bend in the middle of a soil pipe run. I have to install a new inspection chamber, cannot get it square on to the existing chamber due to falls etc so would need a 45 about 2 meters from each chamber. Is this acceptable to building regulations and is it sensible. I know...

I have to join two pieces of 63mm MDPE, the coupler came with plastic inserts. I always thought they were to help avoid crushing the pipe. The MDPE pipe is so thick i wouldnt think i could crush it if i tried, therefore why is it supplied? The pipe is having pumped grey water through it and i...

Thanks all, wessex thats what im thinking it will end up like so its good to know it happened before, thanks Nige, i should have statted my problem is actually that the invert is practically nothing, like 260mm. If they put the ground beam 150 below ground it would be smack in the way of the...

Hello, Is there a maximum depth below floor level a ground beam can be cast? The reason for asking is there need to be waste pipes which would pass right through the ground beam, obviously weakening the beam and probably causing the waste pipe problems in the future. If i install the beam...

Thanks for the diagram, it needs the pipe for expansion so even though my pipe tees before 2.8m i am going to assume i can keep counting the pipe after the tee and would have alot more than 2.8m to a draw off. PRV would be under the floor but at ceiling height in the garage so i will see...
