Drainage pipework advise

[dextrous]

The phrase "optimum gradient" springs to mind.

From the op's description, the longest length will be about 2500mm with a drop of 30mm (40mm pipe in 70mm space) which is 1 in 83 which is just within (well nearly ) the regs.

With foresight i would have visisted the place 2 years earlier before the person that built the extention died. That way i would have known what he had in mind

Ask Derek Acorah to tell him off for doing a silly thing- maybe it WAS the last thing he did

Hi

Right having spent the afternoon trying to dig it out (have only got a little hole at the front) i have reached the soil/sand underneath. There is a metal wire going through the concrete at approx 70mm down (see image below). How can i cut that without special tools? I also have the wall footing to contend with behind the pipe also.

Thanks for all the previous replies, i have even more thoughts going through my mind, hence over thinking big time now

You can cut the reinforcing with an angle grinder, bolt cutters, a junior hacksaw or even a hammer and chisel if you put something below it.

I told you i was over thinking it as i have 3 out of 4 of those tools

Cheers

Like we said, less than an hour from start to finish

 

[Spiceworld]

I wish an hour, It probably did take about an hour to get that far, then i stood there looking at it for the rest of the time trying to think of a way to get around digging the rest

But seriously how will the pipe that is already there be connected when i finally get down there? Glue? push fit? balanced

If i do go down that far with the manifold, do the other pipes just push fit and then back fill the hole around them?

Cheers

 

[tamz]

At least you had a nice day for it

Will be push fit joints.

 

[dextrous]

Almost certainly push fit. And all pipes pushfit (worth chamfering the end of them with a file or rasp, and purchasing a spray can of silicon lubricant for about a fiver)

Foresight? Reminds me of the night I went to a Clairvoyancy meeting, only to find it was 'cancelled due to unforeseen circumstances'.
