Softwashing didn’t take off as I had expected .... mine hasn’t had much use. Are you still after one?
What have you got? prices ? photos?
“Clever injector” or a dosatron (think it’s the DRE25i) . I payed £900 for it and have upgraded the top valve(£50) which allows you to run water through it with out it pumping through the dosatron.
Not sure how much - make an offer?
