Describe the Problem
Is it metallic, earthy, musty, salty, chemical, chlorine-like or sulfur-like? Is it present in hot water only or throughout the home? Those details help identify the next test.
Do Not Mask the Cause
Different tastes and odors require different responses. Carbon can improve some taste-and-odor conditions, but it will not solve every mineral or contaminant problem.
Evaluate the Water
Colonial starts with the water source, symptoms and current equipment, then uses field screening or certified-laboratory testing where appropriate.
