this is hardly news is it

loads having been using water that isnt 000pmm for ages

i prefer zero ifind the dirts moves quicker but i will use anything up to 15ppm

ive used 43ppm when waiting for resin and been able to see minor spotting i generally
squeegee off the water on downstairs windows when used tds this high to reduce impact

where is the sigh smiley, yes gary old news again from lee, it is common sense

Its not actually news, its a proof test.... you done it? You know about it? Thats cool.  Some will be trying this now and hopefully saving money. I get warm and fuzzy inside bought that lol

I've used water with a tds of up to about 25 - 30 with no problems. It makes me wonder why I change the resin when it gets above about 10. Maybe I fall for the hype that it has to be zero.

Also, Lee's paddling pool. Apart from I don't believe it had a tds of 0001 because to get 6" of rain water takes months and months and months, the amount of debris built up in that time would have contaminated the water as it rots and forget the actions of sunlight and green algae, etc etc, what about all the dirt and that in the water?

The purer the water, the more it will absorb contaminates because that's the nature of pure water. I tested my sisters water butt in her garden which gets used regularly and has a lid on it. TDS was 086 yet a paddling pool was 001.

I could be completely wrong though about the paddling pool but I don't think I am.

You are completely wrong , would you like to see the camera that ran consistently? . The water WAS 0001. I cant change that to fit to your perception, I am sorry

Just re- read the post... forgot to mention we had a lot of rain too

I'll take your word for it and sorry, I didn't mean to sound insulting. I did also write I could be completely wrong.

As per the tittle, it's an experiment so I'll be collecting rainwater next time it rains which I'm sure will be very soon.

No problem buddy... but it made me doubt myself so I just went into the garden again and filmed the whole thing in continuos footage again. I got 001 again but this time I did a second test but with  swirling the water around to get any sediment ( which was not a lot) moving. I expected it to be higher. I was amazed - it was still 001. Then I went to my garden tap and tested the water here. That came out at 258.....

I've used water up to 35ppm before for a few months in a row, and I can't put my finger on it, but it does leave behind spots on certain windows.

I think 000 water dissolves impurities quicker. What I found is that when I used water between 10 and 35ppm, I couldn't be as fast then when using 000.
Windows were the water sheeted down were no problem, but partially hydrophobic windows did dry up spotty, same with leaded lights. Unless I slowed down with the final rinse. It was a real mixed bag. This really became much worse when using hot water instead of cold.

So I bought a bag of resin and all was fine again. I like to work at light speed and I don't want to slow down or worry that it will spot.

When I used higher TDS I was convinced that RO water was just fine, but I gradually changed my mind over the few months that I didn't change my resin. I'm sure there is a scientific explanation for it. Made me wonder, if 0 ppm is faster, then is 0 ppb (marginally) faster is dissolving solids as well?

I'll say it again, but if you're using DI resin at all, then you should be using two vessels to save on resin.

Once you ARE using two vessels, then you will not save a single penny by letting the TDS increase even to 002 before replacing and switching over the pots.

Yep two vessels is the way to go.
