Smellywater.com is operated by Randy Schuyler, who created Waterheaterrescue.com in 1995. He suffered from smelly water himself for a long time and had an aluminum/zinc anode in his own water heater. Because its anode rod has been changed periodically, it is now about four times older than most water heaters in its area.
To learn more about how to make water heaters last for decades, visit the main site at Waterheaterrescue.com.

Also, you'll note that we don't provide a phone number. I work most efficiently by e-mail and by staying off the phone. Although I am a one-man company, I pride myself on answering e-mail and shipping products within 24 hours most days. That would be impossible if I were on the phone all the time
