Soil connection to main

[fiaraziqbal]

Good morning all.

 

I am laying a new soil pipe system and i would like to know what you guys would prefer to connect to and why.

 

I have the choice of 160mm PVC pipe or a manhole?

 

Thanks in advance.

Manhole- make it easy to rod if there is a problem, make inspection of flows easier..

Thanks,

 

what would be the easiest way to compete the task? is an internal drop still viable?

Ah thought this was in the ground!

 

maybe a sketch of what you are thinking will help everybody.

Yes its in the ground.  i thought mayeb something like this would reduce the amount of excavation needed.  Its a pretty straight forward connection.  600mm trench. 1 in60 drop straight to the manhole

Internal backdrop (which that image is) are not normally allowed and they prefer the use of external back drops and the use of cored access into the channels. The downside with these use of external backdrops into existing chambers is that they sometimes have concrete encasement to the rings which means you need big access holes to core into the chamber.  
 

That picture is amusing as it wouldn’t pass any BRegs inspection :

- None of the pipework is strapped / retained 

- The bottom bend is a double socket - it should be a rest bend with plain end

- The coring through has not been sealed / made good

- The tee isn’t capped / secured (debatable/dependent on the BCO)

- It cannot be rodded as the tee obstructs the end of the main run 

 

There are much better images and methods..!! This is a good example.

Oh thanks for that, i think as stated earlier i will negate the 160mm pipe connection and get an approved contractor to connect to the man hole.   It is a steep learning experience!
