Domestic water softener installation problems.

As an entirely predictable and inevitable result of not carrying out suitable checks and planning before I went ahead and bought an ion exchange water softener, I'm now appealing to the PPRuNe community to offer any suggestions and advice to overcome two tricky installation problems that have been encountered. Yes I know its my own silly fault!!
Even so, I would imagine these problems are probably typical of many such installations, and quite possibly other PPRuNers out there may have advice to offer based on their own personal experiences.

Problem 1.
The installation instructions require provision for two 15mm hoses to discharge to the exterior of the building. One is for the overflow of water in the event of the float valve failing, and the second is for discharge of brine during the periodic backwash of the resin ion exchange tank. The overflow is not a problem as it could safely be directed onto the path and lawn in front of the house, but pouring brine onto the lawn will quickly have dire consequences for the grass and nearby plants and so is not an option. It occurred to be to have the brine hose discharge into the waste pipe that the sink and dishwasher are connected to, but since the sink U-bend trap will be higher than the brine outflow spout (not allowed as the flow would be uphill) the alternative is to put the brine hose through a drilled hole in the pipe near to floor level with the result that the hose will have nothing to separate it from the foul gasses of the public waste water system. Would it be too optimistic to hope the brine would kill airborne bacteria settling and moving upwards in the hose? Another idea is to run the brine through a hose running along the side of the house to a back garden gully, a distance of 8 meters along which the speed of water might unfortunately be slow enough to form a plug when the pump stops at the end of the backwash cycle and the risk of that freezing inside the hose in wintertime.

Problem 2.
I had anticipated positioning the machine on the bottom shelf of the cupboard directly below our kitchen sink. However, the machine is too tall by 2 centimetres and the cupboard is not wide enough to put the machine to one side or other of the sink. The dishwasher occupies the space to the right and an expensive rotating basket storage contraption to the left, which in order to maintain marital domestic harmony can not be removed. The shelf I mentioned sits on legs 12 cm high and the side walls of the cupboard screw onto its sides. Would it be realistic to try somehow to remove just enough of that shelf in situ to keep the structural strength of the cupboard and at the same time allow the softener to slide in at floor level to fit neatly under the sink?

Should I just return the unit in disgrace, or is there hope yet?
