Ao Smith PP-AS20 Product Preservers Anti-Scale System REPLACEMENT 100291509

Product Description

The AO SMITH PP-AS20 Product Preservers Anti-Scale System protects your tankless water heater from scale formation without adding chemicals or electricity. As water flows, hard water minerals form inactive scale crystals that pass through the water heater. The system is virtually maintenance-free, with filter changes only needed every two years, easier and less frequent than flushing with cleaning solutions.

• Protects your tankless water heater from damage due to scale formation
• Does not add chemicals to the water or require electricity
• Hard water minerals form inactive scale crystals
• Filter only needs to be changed every two years
