Last season I bought the kit to use mains water supply, complete with blue, drinking quality hose. Each time I have used it I have noticed a "plastic" taste to the water, even when used to make coffee. I have tried leaving water treated with Milton in it for a couple of days, but with no discernible effect. Has anyone got a solution (pardon the pun!), as I am concerned that I may have the same problem if I buy new hose, Thanks.
