Broken sewage plastic pipe

[Bobharford]

Hi
Had the drainage done for small add on extension by a company as there was lots of digging and a few inspection chambers. Two pipes coming out of the ground for under the extension base. One the contractors men drove a digger over the pipe coming from the gullet and snapped it .He is offsite ill but I suspect he wants to glue it back on rather then dig out and replace. It is the outlet for wastewater from washing machine and two sinks. I am concerned if a repair would eventually break down and cause a problem with the wooden bearers of the floor.
Anyone have a view on best thing to do ? I have attached a fe w pictures.

Its not really up to the digger driver to determine the appropriate repair (unless you're employing him directly). The main contractor is responsible for what gets handed over to you, you need to be talking to him.
If this was a diy job i'd be thinking yes glue the top of the pot back on (if it is solvent-weld it can be glued very successfully), tape inside the pot with some repair tape. Water level in that gulley pot should never get to the height of that crack, only time it'll get wet is from the pipe feeding it.
Question- who thought it was a good idea to have a gulley trap indoors?

That Gully is easily changed, but if that's going to be inside the footprint of the extension, it needs to be a sealed connection to the drain. That Gully should be removed and a Waste Adaptor fitting to reduce from the 110mm drain to 40mm waste pipe.

It also needs some form of access to allow the underground pipework to be cleaned/unblocked if need arises.

Crikey. Digger driving aside, if they think that's the right thing to use under a floor then this is an opportunity to question every aspect of the whole job, before they start building.

Who's designed and/or approved it? Do drawn designs exist?

Are building regulations involved?
