RO waste water

    I am on a well and have a water softener (for lime and iron) and reverse osmosis filter for the drinking water


    was just curious would it be okay to run the reverse osmosis waster pipe into the attics cold water tank?

    i looked into the tank and the ball valve only fills it to about 3 inches below the overflow pipe

    benifits
    less waste of electricity as all water pumped is being used
    less waste of salt as no softened water going down the drain unused


    problems
    in the (IMO very unlikey) event it fills the attic tank to reach the overflow pipe it will dribble slowly on the footpath


    or am i missing something

    I'm no expert here but are you suggesting dumping the salty waste water from your into your open vented water system?

    Perhaps the header tank you refer to is for your central heating which again I can'e see why you'd want to be dumping salty waste water into it?

    no i mean the waste from the reverse osmosis filter, for every litre of water they make they dumps 12 litres down the drain (read that online somewhere), so its the same water as in the attic tank

    Fair enough I've seen some daft things and if you hadn't mentioned the water softener I wouldn't have said anything.

    So would I be right in saying its the same water with a slightly higher concentration of the crap you are removing from your drinking water?

    Also is there any downside to the operation of the filter if you have a head of water going up to the tank?

    Yeah, that might be a problem, anyone know for sure (whole filter could be moved into attic and piped pure water down instead of pipe waste up)

    Having looked at this for a commercial design. there is nothing wrong with the RO waste water for a tank feed. Where you might have a problem is the head required to get that water from your RO to the attic. (I am not a plumber)

    so best to mover filter and pump fresh water down instead of waste water up, might leave that project till the summer
