    First post, crackin forum with loads of info and lots of helpful windies here :)
    Done quite a bit of research already, can't find any specific info on avoiding slow RO production though.

    I can't have a static tank, and don't want to leave van hooked up to tap for 2-6 hrs or longer
    due to RO bottleneck.
    500 L per day should do, if not replace twin 250's with twin 350's.
    The Idea I had (probably already been done) was to have a twin tank van mount setup (Transit / Vivaro):

    Tank 1: 250 L - labeled "Pure Water" - mounted across loadspace + flush to bulkhead.
    Tank 2: 250 L - labeled "Tap Water" - mounted across loadspace + flush to pure tank.

    Tap tank feeds RO - RO feeds pure tank (booster pumps or normal shureflo to feed RO?)
    Waste - a 3rd tank maybe or recycle back to tap tank?

    End of day - fill tap water tank - next morning pure tank is full, then refill tap tank again.
    So on a 250L at 12lpm thats roughly 20 mins refill at start and end of day.
    The tap tank should keep pace with the pure tank if its a 2020 or maybe 4040 RO?

    I live in a soft water area (not checked TDS yet) so I may get away with DI only,
    but the twin tank RO idea would still cut down on resin costs in the long run or as a retro fit later on.

    Any ideas on the above, would it work, or am I way off track?
    Cheers for any help :)

    Hi & welcome @soap:thumbsup:

    First thing you should do is buy a tds meter and test your tap water

    Second one down the page HM Digital TDS-3 Handheld Meter With Carrying Case http://www.daqua.co.uk/testmeters.htm

    If your tap water is low then you don't need to use an RO at all.
    Let us know what it is when you've tested it :thumbsup:

    Peter, what RO do you use please (Link if you'd be so kind) and is it expensive to buy and maintain ? Im using a small RO with 2 10" filters and a 10" resin housing. Takes absolutely hours and hours and hours to fill my 1000 litre tank in the garden lol. I need to upgrade cause if I get changed to a water meter my bills will go through the fookin roof !

    Cheers that rules out recycling through RO then.
    As for 4 hr hook up - I live in a terraced house on a narrow road with door opening onto pavement (no rear access either).
    I'd have to leave van flush to front door with hose through SLD - not good for 4 hours :)

    Again, agreed.
    I'm jumping the gun without TDS, as you say that is the logical first step.
    Meter on order, will post back with results, guessing it will show up thurs / fri :)

    BTW - cheers for that daqua link, like the price of their DIY soft water kits.

    Nothing wrong with doing this. Sounds like my system. Takes about 2 days to fill my 1000 litre IBC tank in the garage. I'm on a water meter and my bill has only gone up by about £6 a week. Which is nothing considering how much more work I can do now I'm wfp instead of trad :)
