003 is fine. Most people use theirs up til around 005 I think, but anything up to 010 is meant to be ok for window cleaning.

 

Are you using a DI vessel? If so, changing the resin should make it 000.

I'm Di only so not sure about ur ro, tho I think some have a built in Di cartridge, I could be wrong...if so this might need new resin. If not u might need a Di filter.

 

What ppm is ur water out the tap?

Hi 1stop, judging by the pic, it looks as if you have 3 membranes, 3 filters and a di. Unless your tap tds is ridiculous, you ought to be able to get down to o. I'd expect the di to be in the housing that sits alone, so have a look in there to see if there is any resin in, having 3 membranes could well get the water to 3 without resin. Make sure the housing is very tight. If its still 3try new resin. Only other thing I can think is if they are cheap quality membranes, but don't ask me the name of the best cos I forget! But mine are 3 yrs old, 2 of them and on there way out but I still get o tds for about 600 ltrs with the same amount of resin you use, with water going into it at thirty odd.

Oh, did you flush the membranes for an hour or 2? You have to do that when they are new!

Iv opend up the white cylcinder there's nuffin in it is this where the resin goes, if not where does it go . I flushed the water for 3 hours yesterday iv got it down to 004 won't go any lower than that, I'm thinkin is it this resin business thatl will take it down steve stone


Yeh I flushed it about 3hours before I forst used it, where will I find there resin ? Steve

Yep, needs filling! Can't see it being a filter! Tulsion mixed bed 115 is the good stuff. Get it from daqua, 5 litre bag about 25 quid will do about 6 fills, should last you a year comfy, I get about 2 months, can buy bigger bags but at 4 tds I don't see a need, but suit yourself, as has been said you could clean without bothering, but most would for peace of mind. Do you happen to know your waste/pure ratio is? You're tempting me to add a third membrane

Waste\pure is about 50/50 at min its taking far too long to fill but been told if I get booster pump it will speed it up and improve the waste/pure ratio .steve 1stopsolution -cleaning+maintence

I would have thought that rather than buy a second TDS meter you are better off buying a water tester with a known TDS and checking yours against it. Most TDS meters have a little adjustment screw to adjust accordingly.

 

If you are going to use the last empty 10" housing as a DI vessel then you need to buy a cartridge to put the resin into. I'm sure your supplier of the R/O would have one - Cleaning Spot also sell them I see. The DI housing must be the 'last' housing after the R/O membranes.

Should definitely get to zilch. It sometimes takes a couple of minutes to come through at 0 but I'm guessing you've waited. Is the housing as tight as you can get it, even if it doesn't leak outside, if it isn't dead tight the r o water can seep through without going through the resin, happened to me once, couldn't figure out why r o and di read 12 with new resin
