Why Water Flushing & Filter Replacement Is Essential
When wildfires occur, ash, soot, and other harmful particles can enter the municipal water system. This can lead to:
Contaminated water lines that affect water quality
Sediment buildup in your plumbing system
Clogged or ineffective water filters
Potential health risks for you and your family
To combat these risks, it's essential to flush your home's water system and replace all water filters to restore water purity.
