Can anyone help please? I have contractors who want to run pipes from rainwater downpipes into an inspection chamber that is a combined foul and rainwater drain.
The inspection chamber is a base plus a riser and the contractor wants to put the new pipes coming into the chamber at a level part way up the riser, so cutting a hole in the side of the riser, and then putting the pipes through the hole so that they finish hanging in space above the base of the inspection chamber.
Is this ok to do?
I understand that it saves them having to excavate down to the base of the chamber and finding a spare connection spigot, but is it ok to do?
Thanks

wrt the points
1) because the building warrant specifies it into the drains
2) there will be a trap/gulley which presumably would prevent that, and actually having the end of the pipe suspended in mid air would make it more difficult for them to get up the pipe than connecting the pipe into the bottom of the chamber!

Your opinion that it is a bodge is helpful, thanks. Is it actually against any building regs does anyone know?

Building Regs makes no particular mention of how connections such as this are to be formed, but it defers to the British Standard BS EN 1610:2015 and possible (depending on BCO interpretation) to Sewers For Adoption, both of which require such a connection to be a dropshaft

Occasionally, some BCOs will permite a 'hanging' connection but there have to be extenuating circumstances.
