1 1/2 in. Zinc Pelletfor Water Heater Pkg/2

Zinc pellets fifght against odors created by the minor formation of hydrogen sulfide in the water heater. Zinc pellets can be added in the water heater at the same time as the magnesium anode is replaced with an aluminum one. Combined with an aluminum anode, these zinc pellets act directly on the anaerobic bacteria, preventing unpleasant odors similar to rotten eggs that seem to come especially from the hot water.
