    apart from regular timed flushing every hour or so in use.

    depends what it's fouled with...
    if mainswater probably limescale, if RRO probably organics...or both
    afaik commercially they use a flushing set up with very acidic and very alkaline chemicals.
    both pretty nasty.

    how are you running the RO?
    in RRO they typically only last a year if your lucky, due to organic contamination and low rejection rates.
    if mains water should last years as long as they are not run with low rejection rates and regular timed flushing.
    yeeehaaa!

    Cheers dave, I’m currently running RO as a feed inlet but I’m thinking about running recycling hence my hope of cleaning the membrane to give them longer life expectancy

    most people just replace them,
    from what i picked up from some others running ULP 4040 i n RRO they change the membranes about every year...

    Yeah that’s what I’m trying to avoid. Was hoping to make £800 a year £500 a year ��

    Iím sure Andy Finch suggests they can be cleaned??

    I have seen it somewhere where 4Ē waste is used to store them in a cleaning fluid.

    Iím assuming they are not going to come out like new but even if it doubles the life itís worth it..

    I think it takes some time so you would have to have a spare to have it on rotation.

    Give Andy finch a call.

    Yeah this is what I’ve seen, heated solution flushing. Just don’t know the solutions and methods etc.

    I don’t like calling Andy for advice without buying something from him I know he’d be able to answer my questions but also good to have the information on here.
