2 X Di Resin Tanks

Ok, so i take it if you are in a soft water area and you are already getting a zero reading through the 1 vessel then its pointless, but if you are in a harder water area and not quite getting zero from one vessel then the 2nd vessel will come into play ?

 

Thanks guys......... Good guys on this forum without chips on there shoulder, always there to help . cheers

I've been asking about this too , the way I'm going to do it is have 2 di vessels in my van (I have one in my van already) . I will fill my 500ltr tank up with tap water and as I work it will come out of my tank through my 1st di vessel which I hope takes the reading down from 240 to the lowest possible then into my second di vessel and come out of my brush head as I'm working at 00.00

Sounds like a plan mate, at least your not messing about connecting everything up outside the van 1st, and if you need an emergency fill on the jobs its just a simple fill to the van. To be honest i can get away with the 1 di vessel and get 00.00. I just didn't no if they was still an advantage in using 2, but i get what people are saying now. When i 1st started i was totally clueless and was messing about with ro units and all sorts. Realised later i didn't need it lol.

I'm hoping I won't have to keep buying loads of resin all the time I've got the new Merlin RO system on top of my tank in my van I have to drive to my mates house and wait around for 3 and half hours for my tank to fill, but then it takes the water down to 15 then when I work it goes through my resin, my resin lasts forever but I just can't be dealing with hanging around for it to fill up

Steve, I'm not sure you understand the twin di method. Maybe I'm reading your posts wrong? The advantage of twin is to keep using the resin past it's shelf life. Ie when the first vessel has crept up to say 006ppm, then that vessel becomes the first vessel and the second vessel will have new resin in. The idea of the first vessel is to take your tap water down a whole load of ppm before it hits the new resin. This will make the second vessel's resin last longer than it would by using just the one and in turn saving you money.

 

Hope that made sense :-)

No you haven't been reading my posts wrong, that's the answer i have been looking for, it makes perfect sense now! So basically it allows you to get the maximum use out of the 1st vessel, with one vessel you would be throwing your resin away once your ppm was out of range. But with the second vessel in place it allows the 1st vessel to keep working to a degree and in turn the 2nd vessel isn't working as hard. Nice one pal that has answered the question.

 

I suppose rotating the vessels would help ? Like once the ppm on the 2nd vessel creeps out of range you would throw away the resin in the 1st vessel and move the 2nd vessel to the front and the new resin would go into the new 2nd vessel, so that you would never be throwing away any resin that still has life in it.

No probs mate , I've looked on eBay but bit confusing as some of them say pressure di vessel or something like that I thought they were all the same

 

They is a link on here, it under a thread called WHICH RO UNIT, if you scroll down they is a link to the auction site with them on, if you click on other items for sale they have all different sizes etc..... they are not badly priced, but it all depends on what you want to pay tho!

Arrrgh can't find it lol

 

Just tap which ro unit in the search, and scroll down 3/4 of the page, then they is a link for a ro and a link for di, the di advertised is only small but in other items they is bigger ones....they are all reconditioned di vessels....... specifically for window cleaning/valeting
