I responded earlier to an inquiry by EM. Just checking on your credentials to properly evaluate any chemical issues with the NSI system. The Texas State authority did not mention any of these.

Using Titanium electrodes (long life) they can split the salt and water and make Clorox bleach on demand, slowly over time.
