Dunno if anyone can help me with this- when I occasionally clean conservatory roofs, I use an Ionics "domestic" system, it's just a disposable cartridge of that resin stuff that you connect to an outside tap, and a pole of course.
The problem is, the cartridge only lasts for 2 or 3 roofs, so at 30 quid a time, they aint cheap.
The Ionics guy told me that because I'm in such a hard water area, I need an "R O" instead, and it would mean buying a van or trailer system, which I don't want to do.
So my question is, would it be possible to use an "R O" in the same way, i.e. carry it in the car, and connect it to the customers tap? And would it work out cheaper?
P.S. I don't even know what an R O is!
