Some people swear by adding a little bleach to their well or water heater. It works because chlorine is a powerful oxidizer, same as the air in those fancy filters.
But never mix bleach with other chemicals, and test your water afterward. You don’t want to trade a rotten-egg smell for a swimming-pool taste—unless that’s your vibe!
A better idea is to use a chemical feed pump. It injects a tiny, controlled amount of bleach into your water line automatically. It’s like a slow-drip IV for your pipes.
