Can I connect a stand pipe to a soil pipe?

[jacoscar]

Hello, I’m considering buying a water softener and I’m planning where to connect the waste pipe and the overflow

The water supply into the house is in this toilet, but the water softener will have to go in the room to the left of it (when looking at the picture)

I need to somehow connect the waste pipe and the overflow to the soil pipe or the white waste pipe coming from the toilet sink
What’s best to do here?

And can I just bend the softener’s waste pipe to create a sort of trap or do I need a proper one?
What about the overflow pipe?

Can I connect a stand pipe to that white pipe or to the soil pipe?

You'll need a Standpipe as a minimum, which can be connected directly into the stack using another strap boss, or couple into the existing waste in the pic if easier.

thanks!
I think the height of the stand pipe should be lower than the overflow outlet of the softener, am I right?

I don't actually have space to drill into the soil pipe, unless I drill it from the room to the left (which is where the water softener will be, just below the consumer unit by the way, is this ok?)

If the softener discharges by gravity, then yes.

Should be ok, as long as the electrics cannot get wet. Just bear in mind, you'll need suitable access to clean and apply solvent weld to the stack, you need to get the boss attached securely so it doesn't leak!

Access to apply solvent weld is not a problem, the issue is getting a drill on the side of it, I’ll have to cut a hole through the plasterboard on the left, from the other room

The drain can discharge to a height of up to 2m but I think the overflow discharges by gravity as this is usually just pushed through a hole in an external wall...

Is it better to have the stand pipe in that boxed in together with the soil pipe or in the other room (together with the water softener, consumer unit, meters)?

Whatever suits ease of installation and aesthetics I'd say.

The stand pipe would need to go here as there is not enough space in the box where the soil pipe is

After almost 2 years I finally have my water softener, I just need to install it. Can I connect the waste to the existing basin waste using one of these? https://www.screwfix.com/p/washing-...zwPdZGgnnJ32sQUUYERoCvtAQAvD_BwE&gclsrc=aw.ds

I'm not sure as the connection would be AFTER the basin trap
