A: This unit has been out of production for quite a while and we can`t think of any source.
There is no direct replacement available and the nearest would be the Supajet 100 which has water supplies on the left hand side, it is also mains voltage so a new cable would be required and some alteration to the pipework.
It can be ordered online by clicking on the link below.
