    Spoke to Mark who made this video and he said for me this is the way to go. I only need 100 litres a week on Saturdays. And for me this is better than an RO. I think the principle behind it is pump the tap water into the first DI which is a bit rundown (meaning the TDS coming out is 16 or something) then put it through the next DI which has fresher resin and this brings the TDS down to 0. Is this right? Anyone done this?

    He reckons can make 4000 litres for £70. I live in Bournemouth and TDS is high (over 300 think), but this should still work here apparently.

    I go through roughly 5500 litres of water per week all through a twin DI !

    Its not as expensive as it seems.

    My water is also 110ppm

    Just called company who sells DIs and they said they can sell two with resin for £180, He recommended two 11 litre ones.
    In my situation I may not have access to water in garage so might have to drive or carry the DIs 40 metres down the hill near my flat where there is a tap. Or drive to girlfriend's and fill my barrels which will go in my car through the two DIs. Are two 11 litre ones practical for this or would I have to just leave them in once place (e.g. garage)?

    Would two 11 litre DIs be small enough to take in and out of car quickly and set up n next to tap? Are they heavy?

    My 11 litre vessel is quite light so no bother
    The spectrum 25 l one tho is a different story certainly wouldn't want to be lifting that
