Help! Water leak

I sanitize the tank when I de-winterize. I have no problems using water from the tank. I fill with fresh water and put in the appropriate amount of Camco Tastepure Drinking Water Freshener. It is essentially bleach, but made for drinking water, so it keeps the water in the tank safe to drink. Since it is made for that purpose, I am pretty sure it does not have any added ingredients that could be harmful. That is not necessarily the case with laundry bleach. We've been doing this since we bought the trailer in 2015 and have had no problems using the water for drinking, cooking, and washing/showering.

Also do you use the freshener every time you fill the fresh water tank throughout the season or just a couple of times during the year?

I use that taste pure as well. I've used it for a2 or 3 years. I also buy it from walmart. I don't drink the f/w tank water, but I don't want to use unsafe water. Occasionally we are not hooked up to city water, and use it to wash, or brush teeth. I want to be sure it's clean. 

Are you talking steady stream or occasional drip? The tank when filled will sag. As the weight of the water is removed, the tank bottom will flatten out. This is not immediate. As it flattens, it will allow water that was trapped in the sagging area to reach the drain. That could be it.

Originally posted by richardd I just replaced the Anode rod. I noticed the water tank drain is still leaking. I took the cap off yesterday. Maybe it takes awhile, but shouldn't that stop leaking?

Okay. Perhaps I am misunderstanding you. Which tank drain is leaking? Is it the fresh water tank, the water heater tank, or something else?
