Found a flat and it has a garage nearby- wondering if I could run a window cleaning business from it. There's a garage and could run a 40 metre extension lead from my flat window and there is an outside tap about 55 metres from it. There is road and communal gardens between the garage and house- could I run a small RO unit in the garage or is this a stupid idea? is it better to just purify the water in a van outside the flat? On my budget finding it hard to choose a place to live which could also accommodate an RO.
