How fast does a Corro-Protec powered anode stop the rotten egg smell?

Published October 21, 2025

Our response

In most cases, the rotten egg smell disappears within 24 hours of installing a Corro-Protec powered anode rod. The system uses a low, safe electric current that instantly stops the reaction between sulfur bacteria and the sacrificial anode, which is what creates the smell. If the odor is strong or has built up over time, it can take up to a couple of days for the smell to fully clear.
