I fill my 650 litre tank through twin di vessels but do it slowly over a period of about 5 hours and find that the resin lasts onger by doing this as well.

[jouk45]

mines lasts around 8 months, but now will last over a year, as i now use the wet scrub method, saving loads of water now, if you use resin, run it slowly, and you will get almost double the life from your resin,

I think everyone is getting confused with the whole DI and Resin. I think some people that have replied to this post are on about the small DI's. Mine is 25lt, takes a 25kg bag.

so are two smaller di vessells better than two larger ones . if you have your di after the pump does it put extra pressure on your pump

and that only last you 4 weeks, something not right there, should last you around 4 to 6 months, the bigger the vessel, the more your resin lasts, 55ppm is reasonably low

[Orange WC]

Why should it last so long?

Joe, what's the wet scrub method? Scrubbing the glass first with the fllow off?

[williamx]

out of a sack of 25 kilos of resin you should be producing 9090 of pure water.

500000 divide by your tds tap water 55 = 9090

If I was you I would check the flow rate of the water that is going though your di tank, it might be going though too fast.

I would also check that the tap water is going though the inlet connector and not the outward one.

tds round my way is shockinn 28-32ppm i mean how am i to cope LOL

[windowinfo]

  TDS ONLY 22 - 55ppm !!!!!  from the tap!!!!!!!

 Im in the south east and mine is a bit higher than you lot,
 
 189ppm from the tap!!!!   

 any chance i can hook up a hose from your house lol!!

 I use double d.i only
 my tap water is around 300 ppm
 but i only use w.f.p for 1st floor and above and i only do 3 days a week at the mo

 but 1 bag of 25 L dowex resin as lasted around 6 months and i still have some left!

hi what size is your d.i are you using? my ppm is just under 300 and was looking at doing ups only aswell

[allan wood]

if you go double do both containers have to be the same size

[dan hughes]

I'm twin 11 ltr DI bottles.

"Used" one as water goes in to my tank.
Then the 0ppm one after tank, after pump to my leaky hose .

I bought one bag last year, and one last week. My "used" DI bottle was up to and equal my house tap water  022 ppm.
So I changed it.

Whilst on site the highest I've found my way was 112ppm - I nearly passed out from the shock of it !

I like this set up coz I can fill up quickly and at most sites (where there is availability of a tap) and it's cheap.

APART from the times like last week, where I was working hard as the van filled, only for one of my connections to blow before the Shut off tap and fill my van up to the doors cill level !  not happy .
It's a van not a boat !

Can you explain why you think this to be true?

[biggles]

pure hydro , orange is getting 20000 litres of water so that is better than your calculations of 9090 and hes only using one di cannister ?

It doesn't matter if they are different sizes.

Joe, what's the wet scrub method? Scrubbing the glass first with the fllow off?

yes, but only on maintainance cleans, not first cleans, just wet the glass lightly, then wet scrub frames and glass, then rinse of, i use less than half of what i use to use cleaning this method, before i was over doing it, you get the same results using the wet scrub method

Those resin calculators are a waste of time.

For instance what brand of resin was used? We all know purolite is a very poor resin while dowex or tulsion will outlast it by far, even more so when utilising 2 DI's.

i cant see how 2 resin vessel can save me on resin, does anyone have real proof of this, the real idea of 2 di resin vessels, came about years ago, it was for folk with high tds readings, who mainly do commercial work, and this method was to fill up on site, saving them running back to refill, if they had a tds of say 400 or more, one vessel was not enough to bring that hardness down, so the 2 vessels where born, i think over the years the whole thing has been misinterpreted, 2 vessel will still give the same results as one vessel, i think it will still come to the same calculations when the resin is spent, prove me wrong, becouse i just dont believe it
