What ppm do you change your resin?



Recommended Posts

Jonathan Harwood

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

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 [emoji41] 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.)

I change mine at .005 tds and never had problems. I'm in a hard water area and Tap is usually around .400 tds.

If I get problems with spotting it's rare and usually around vents. Nothing to do with quality of water

Not 100% if mine or your water comes from hanningfield resevoiur as I was once told there where lots of underground pockets of water, also your tap water ppm seems a fair bit higher than mine.

Essex & Suffolk supply mine and I believe it is from Hanningfield. My tap tds fluctuates. It has been as low as .375 but it's not often.

Mostly it's between .390 and .425

go gas m8 its much cheeper under £200 and ur set upG-)

Wow thats high ppm -375, I can't imagine. Our ppm is 37 in my town and my DI tank is at 1 ppm and I'm contemplating changing the resin, I'm feeling spoilt after reading what some of you have to deal with. Good for you to have it figured out though....well done.

I ended marrying a second tank which read 3 to my large tank which read 1 and I ended up back at 0 ppm reading going to the watered pole. I'll keep an eye on it but putting a second tank to my original helps us so much when we run into a higher than 1 reading.....just a thought for some who may want to try this.

Been working for last 2 weeks at 006-009. No spots and no complaints, and I have some very fussy customers who check my work every time.

I change my resin before it gets to 4ppm. It seems to last at 3ppm for ages. I have cleaned my own windows with 5ppm once to experiment and the results were spotless. The other day I checked my eater and it was 8ppm! I used it and ordered some resin sharpish. I am in a hard water area (300ppm).

I had no complaints from the 8ppm BTW. Although I dont like using above 3pp.

You should be able to clean very well with 004 ppm. I done mine today at 003 and the windows are perfect, you might get spotting as seals leak and the dirt in air catching in droplets, its never goign to be bang on perfect is it!!!! There will be some kinda mark somwhere, its out in nature and dust fling around. But in the main I never had a complaint with WFP only compliments. I think its all in the rinse, anyhting up to 004 ppm you should be getting great results. Plenty or rinse :)
