    So ive been cleaning windows for 2 weeks, making 600 litres a day. My resins all ready needed changing (running 2x 25 litre tanks). Does this seem right? Expected it to last a lot longer. Tds of tap water is 60, first tank takes it down to 20, last tank 0. Thats about 60 quid a month on resin running at 60tds before it goes in?

    I'm DI only and my tds at source is 50 - 60. I run two 11ltr DI Vessels. 400 ltrs every day. Change one vessel every 6 - 8 weeks.

    So to me it doesn't sound right at all. What Resin are you using?

    Just done a bit of research, if the waters at 50tds, it should make 12000 litres before tds goes up. Mines lasted 10 days at 60tds. Is there a way to make it last longer, for example more tanks?

    How are you testing? I have had a couple of dodgy tds meters in the past.

    Got a decent tds metre, the last 2 days a few windows have come out terrible. Checked tds and its at 20 after di tanks! Havent bothered checking as i expected it to last at least a month. Only think i can think of is i leave the tanks in the garden 24/7. Maybe the heat from the last 2 weeks has affected it..

    Not sure mate. I can only speak from personal experience. My 11 ltr Vessels are in the van, fitted after the pump. I run tap water direct to tank and purify on demand via two vessels.

    Are you running water through them too fast? That can cause a channel through the resin and some water will no touch the resin or so I have been told.

    Someone will know more than me. Give Doug at Daqua a shout he knows about these things. He is on here quite often.

    Cheers buddy appreciate the help, decided the tanks are going in the van and gonna set up after pump see if that helps it. Gonna give them a good shake around daily too incase they do form a tunnel and water just passes through.

    Bang on SP;)

    Sounds to me like you're filling your tank through the vessels at full mains pressure/speed? Put the vessels on the van & pump through them, filling your tank with tap water. I think you'll find this cures your problem.

    Also if the vessels are in the van the natural movement as you drive with stop channels forming.
