If you get ANY resin coming from your DI then you have a faulty DI IMO. I've used two 11Ltr ones for over 4 years & never had any resin get through. The higher the flow through a DI the less the time it gives 000ppm.

Tony

Yes but it will still produce the same amount of pure water. You may have to slow it down a little when the reading starts to rise, but by then it's time to  start thinking about changing it anyway.

Peter

So why not still have the di's in the van & fill tank in no time at full mains pressure & be left with the option to fill up on site? My advise is a no-lose situation.

In my experience (regardless of what others say) a slow flow rate still produces more pure water, i've done both many times & found the slow route to be more productive.

Tony well tonight ive filled the tank in about an hour with tap water and put the di after the pump
like you said ans will see if this is better as today my ppm went up 2.. 6ppm in no time ,so we changed the resin
and away we go Edd

You could have shaken the vessel, put it in van & had 000ppm tommorow without changing the resin. anyway, you'll see a difference now it's in the van.

Having said that, what brand resin you using?

Tony

purlite

which is best iyo

purlite

Thats the worst mate IMO from experience too!  I use DOWEX now & it lasts much longer than purolite. Once purolite hits 001ppm you've had it, it'll be spent in a day. I've had dowex stay at 001ppm for 2 weeks! & then only slowly rise.
