Sorry guys should of mentioned, I'm in colchester, very hard water worst in country or on par with a few others, it's put through an ro and di, my question is how much do people using a ro pay on average? Because if I can get pure water for 3p a litre locally which always reads 000tds then is this cheaper than maintaining an RO at home and paying higher water bills, bearing in mind 60% of water is wasted and I need 350-400 litres minimum a day?
It seems to me that 3p a litre is pretty good?
