My PPM is reading only 3 currently, what reading should I wait to before changing the resin.
When it is too high to be confident you will have no spotting
I have an ro and don't run through di but get perfect results with 4ppm and have used it at 13 with no spots but others..i think spruce is one of them has said that 3ppm will cause spotting where they are
No one can say what your water will be like
010 at the most but i let mine gpo to 005 usly
I only go up to 5, and some will not go past 000.
Know one wants to push there luck, but if I changed my resin every time it hit 001 then I would be broke.
Recently I had a job with no water tap, Big first clean and needed pure due to height and obstacles,
This was when my water hit 10 ppm, Well I changed the resin and filled some bottles with 000, but kept a couple of the 10S for the initial cleaning and will be trying these on my own house soon.
I had mine at 12 last Friday & it was fine & I'm in a hard water area.. I done my first resin change yesterday & it went to 0.8 after.. I done a first clean what hadn't been cleaned in 2 years today with fascia & windows & left everything gleaming but I think I going to have to have a little fiddle around as I'd like for it to be down to atleast 0.3

It was 6ppm daveyboy. When out tap tds was at 250+ the rejection rate was 4ppm. A supplier told me that I didn't need to use resin as 4ppm was fine for cleaning windows. However, the difference between 4 and 6 was far too close for comfort.
We also live on the North Coast so sea spray is another issue we have to contend with. So for me, water needs to be 000 to be absolutely sure. We also rinse more than we do for in land customers.
I bet the salt is a right pain
It's weird how it differs everywhere
I can clean with 12ppm and know it is fine although i wouldn
I cleaned with 003 on my own house and got some spotting, and just like Spruce I change as soon as I notice any change above 000 my tap water is approx 260 RO is 006 it's a hard water area for limescale so don't know if that's a major factor with the water in my area.
I'm sure that must make a difference.
I also don't believe that we can see faint spotting from the outside like you can from the inside in low level light conditions. Our water isn't hard with very little lime and I noticed it at 6ppm although I was looking very closely. I doubt a customer would notice it with a casual glance. (We do have a little lime in the water as we occasionally have to descale the kettle.)
spruce im in same boat as work on sea front most of my work is on the coast and 000 there is a must for shorealso hot wfp is a must as well to get the best resalts salt is the big thing in town i go through loads of water as well more than inland thats for shore
