According to Ontario Ministry it is not recommended to put septic products into the system. We moved into our country home last Aug (2010) - first time we've had a well and septic system. We have a water treatment system, including ultraviolet and reverse osmosis - expensive and supposedly top of the line. However, we've had a persistent bad odour in our bathroom vanity taps from the beginning. Contrary to our government advice, we flushed 2 doses of your Septo Clean product into the toilet today and much to our relief and surprise, the smell in the vanity tap is gone.  We'll keep using your product - thanks a bunch for giving us a solution for what we are worrying about!!!
