I am trying to figure out how to fit a (non-electrical) water softener in my downstairs bathroom where the supply pipe enters the house. It might be made to fit under the washbasin but only if I could relocate the trap from directly under the basin back about 20cm to nearer the wall. It seems to be very unusual to have a trap that is not fitted directly underneath a basin so I wondered if there was a good reason for this or if it is just customary practice.
