I live on the south coast and pay £50 a calender month for unlimited water. On average I fill my 600ltr tank 3 times a week, 12-16 times a month which is 7200-9600 ltrs. The person who I get it off has around 10 customers and is making money from it. Good thing about it aswell is that its a brodex static system and comes out at 000 so your resin lasts a lot longer.
no ,keeping it going getting stuff from it you know how many people look at e-bay window cleaning. i know you want some water boy, just ask.
