Water Softener Plumbing

[Spinny]

Struggling over best option for plumbing in the Monarch Water Softener - see sketch.

Builders plumber has put in a stand pipe with a dry trap that is connected into the toilet waste pipe with a strap boss directly behind the WS position. This seems a pain for several reasons - it isn't visible - it stops the WS going back against the wall which then blocks the doorway into the u/stairs cupboard - is it a good idea to connect a water softener to a toilet waste pipe.

Going out through the wall of the house seems like an option but would mean putting in an outside drain by digging up the hardcore and messing with the underground drainage pipe - maybe breaking the pipe run to the left of the larger chamber to put in a Y junction. This outside drain would presumably need a trap to stop smells outside from the drain.

Presumably I would have to put 2 holes through the wall, one for the discharge drain pipe, one for the overflow. Then presumably neither would need a trap or tun dish or anything.

 

Thoughts ?

Anyone got any photos of neat and tidy water softener plumbing work ?

I don't know if these are of any help. I would have thought turning the water softener through 90 degrees so it's parallel to the outside wall would improve access to the cupboard.
