Elevated Tin (in two different Tanks)

Wtyson254 · Mar 3, 2021

My ICP for Both my Waterbox 70:2 and my 5 gallon pico have resulted, with Highly elevated Tin. These systems are completely separate and only share the same RO water should, holding bin, and saltwater mixing station.

currently the RO water shows a TDS of 0.

I know elevated Tin is typically due to corrosion, but I’m u sauté of the source.

It's probably from your plastic tubing. You can read all about in the great post by Dr. Jim below.

Tin Leaching from Common Plastic Tubing and a Very Inert Tubing that I Found

I'm sure many of you are tired of me posting about tin leaching from plastic, but for those having "tin problems" this might be helpful. Although I found tin leaching from many plastic products, I found that plastic tubing may be the worst culprit. I performed "soak tests" where I would soak...

Would be useful to know the level. lol

Don't blindly accept the word of the ICP companies of what is a problem and what is not. They tend to flag everything.

Plastic is often an important source.

The other tank is also around 24

Those values may not be high enough to be an issue. Many folks see levels like that without apparent problems.

What about the elevated Zn ?

Probably not an issue, but I am not sure what level a problem begins to be seen.

I've had TIN problems with levels at 9µg/l on first test then 10.20µg/l on ATI tests. I've recently upgraded my waterbox 220 sump with a Trigger Platinum Sump with a Fleece roller. The last ATI test I got back 2 days ago show 0 TIN now. Since before it would increases and now its at 0 suspect that it has something to do with washing filter socks in the wash machine.
