    How often should you change the pre filters and membrane?
    Do they look dirty, are there any indicators?
    I've looked around and there are a lot of different opinions, any advice appreciated.

    I got told 3 months for pre filters, I reckon they could prob go a bit longer, depends on how much your pure your producing and your tap TDS.

    R/O should be good for a few years if the tap pressure is good and the pre filters are maintained.

    A key indication that you filters need changing is when your pressure gauge drops you then know your filters are clogged.

    Plenty of filters on the market but always ask for the specification as this will give you an idea how litres the filter can treat.

    In some cases you may get more or less but totally depends what is in your water.

    Due to this heavy rain people are changing their sediment filters a bit more regular as there is more sediment in the water at the moment.

    Cheaper doesn't mean better value for money as if you worked out the cost per litre in the long run the well know brands like Pentair give you better value for your money.

    I have 2 gauges, one before the sediment and one after the carbon block. I can see when the sediment needs changing when the gauges are reading different pressures by a margin. I also have them in clear housings so I can also see the the muck on the sediment filter.

    A carbon block lasts me 3 months but I often have to replace the sediment filter every month.
