It also helps to clean your brush from time to time as well.

001 tds can streak, it all depends what the dissolved solid is.

I only use 000 because I believe the spiel I churn out to my customers.

No it cant as you wont see 1 part per million with the naked eye, TDS is a measure of conductivity not a measure of what
can be seen with the eye.

yes it can, completely depends what the solids are.

you wont see 5 or 10 pppm with the naked eye, nor will you see 500ppm with naked eye, who can see solids in their tap water?

depends whats in your water, just because yours is fine at 001ppm doesnt mean someone elses isnt.

Nobody's talking about what you can see in the water (roll eyes) its what's left on the glass after the water dries, if your seeing
anything on the glass at 1ppm  its nothing to do with the TDS and that's a fact.

Well, thanks for clearing that up for me. I hadn't realised how completely wrong I'd been for the last 10 years.

As far as the OP goes, please yourself how you go about DI, you can go with 020 and maybe be fine, and probably save yourself a couple of ££ or you can go with 000 and eliminate doubt.

[jk999]

I usually go to 020 Max without problems, sometimes I get problem if the weather is crap, but to be honest everyone that knows their customers know which ones complain about the odd spot I know that in my case out of 100 %of my customers is about 5% so if I get a complaint through them  I would just reclean but never had to do one in the fifteen years of wfp

Yes you have been completely wrong for the past 10 years and are still wrong, you have just set your doubt level slightly lower
than others but at the end of the day if that what your comfortable with then there's nothing wrong with it.

[SeanK]

Zero parts per million is just a measurement of the amount of dissolved solids we have in the water it doesn't mean its
free of dissolved solids, there's still plenty left for a parts per billion machine to remove.
Unfortunately some people think that by removing one or two extra parts per million the water suddenly becomes
something different.

The main question is, are you gonna be a gulliable sheep who believes everything a sales man tells you. (Not many truthful sales peoples around).
Or, enter a brand new period in your life where you experiment and push the boundaries to find the truth for yourselve??

Practice on your own windows over a wknd with a slightly higher tds etc and find out. Eradicate doubt and save some money in process.  I know for a fact that in my area i can work upto 016 and provided i do a good job, i know it is fine. I know this because i put my big boy pants on and tried. Even went back on some windows just to double check. Explained to my customers i have changed my filtration process and so was just checking on my work. You would be suprised how this impresses the customer! So its a win win.
Or keep little boy pants on and spend loads of money renewing resin (guess salesman win win) because of being convinced that above 000 tds is scandalous

Or, if you're going to use resin at all, use a double vessel setup so you can keep TDS at zero and it won't cost a penny more than letting it drift upwards.  Now that's what I'd call clever.

I did 000 for five years, until one day I checked tds and for some reason it had shot up to around 018 panic swept in checked some house spot free so since then never relied on 000 anymore

Not noticed anything on the glass at 1ppm never looked

i have however noticed spotting (quite badly) at 4ppm

100% down to the water on that occasion, i test cleaned it on my downstairs window after a complaint, the entire glass was spotted, not runs from the seals, the entire glass had dots on it.

Its not fact, its a load of b******s thats what it is

Unfortunately some people think that by removing one or two extra parts per million the water suddenly becomes
something different.

This is pretty obvious, however where do you draw the line?

what level of tds is safe? 10? 20 ? ? 50 what?

Of course 000ppm isnt pure its just the purest most of us can produce with what available.

It makes no sense what so ever to guess what a safe level is when you can just use 000ppm and be as safe as you can be.

Ive seen spotting at very low levels and coulndt care less about what i "might get away with" or what anyone else has experienced.

At the end of the day we can all do as we please and go from our own experiences

but please dont try to pass off what you are saying as fact, its merely youre observations it has no scientific evidence to back it up

Bang on SeanK, beggars belief what utter bollox is spoken on here at times!

[capn sparkle]

I've been cleaning with 20ppm for months now, my resin is spent and haven't bothered changing it

That's what me Mam in  Buntingford said!!!!

Seriously Lee - Built about 900 houses recently - is Buntingford near your round? Been asked 4 times recently (only
visiting my parents)

You don't need science just a bit of common sense, divide a litre of water into one million parts and one of those parts will be the
dissolved solids in the water per 001TDS, add another three and put them on the glass and that's what you will have left on the glass after it dries.
Doesn't matter what it consists off there no way its going to cover the glass in spots. (roll eyes)
A tds of 004 = 4mg of dissolved solids per kilo/litre of water.

[benny donnelly]

guess im going to experiment a little more myself on this and see just how are i can push the tds before it starts to leave deposits as since i started ive always kept it 000 for peace of mind but if this can go to 30/40/50 then really defeats the purpose of wasting resin/money

[Arnold Palmer]

Unfortunately some people think that by removing one or two extra parts per million the water suddenly becomes

Which people?

There is no point in running your water at anything other than 000 if you run it through 2 bottles. By the nature of the design it actually means that you are wasting resin if you do.

You missed the point about the 001, you're probably right, it's very unlikely to spot at 001 no matter what the dissolved solid is, but like I said that's not my point. My point is that there are some people who can clean with 050. My tap water is 050. The dissolved solids in my tap water will be different to their filtered water leaving different results. My tap water 100% without doubt, leaves streaks.

It's no use advising someone to use 020 when there are so many variables. Maybe it is fine for you, maybe it'll be fine for him. Maybe it won't. Use 000 remove doubt.

[Perfect Windows]

A tds of 004 = 4mg of dissolved solids per kilo/litre of water.

4 ppm would be 4mg dissolved in a thousand litres of water, not one litre.  So just under a teaspoon of soluble impurities in an IBC brimful of water.

And that's the key.  Run two DIs and apart from the initial cost of one extra dose of resin and an extra DI vessel, there is no cost implication at all in using water at 0 TDS.

Omg who cares what it does run everything through your ro or just di as some do check tds people that like 000 then once it rises change resin those who are more confident then run it on what Eva highest tds they will run it on we are window cleaner s not bloody scientists.

Someone asked the question so someone cares.
