Replacing our kitchen involves moving the sink to the other end of the room - at the same time installing a waste disposal unit.
The original waste pipe goes out of wall behind old sink and down to one side (about 4 feet I guess) into and above a gully grate.
The new sink waste position will be about 12 feet from the same gully. I think that is too long a pipe run, if I understand what I have read about the topic - true?
So what is the solution? The wastes (old and new) are on the same outside wall. Is there something I can do with the 40mm pipework? or should I lay a new gully near the new sink and pipe that to the old gully (still used by bathroom and drainpipe from gutter)? The second seems a bit drastic just to get rid of sink waste (and dishwasher).
On the subject of waste disposal units - they have to be discharged below the gully grate - is there a better way of doing that other than cutting a hole in the grate? Is there some special fitting?
Thanks
