How to Change Water Filter Cartridges
Swap out sediment, carbon, and specialty cartridges in whole-house and under-sink systems -- the right filters, the right schedule, and the correct order for multi-stage setups.
Common Water Treatment Problems
View All →Bad Taste or Odor in Water
Water that tastes or smells off -- chlorine, rotten eggs, metallic, musty -- has a specific cause for each type. Identifying what it tastes or smells like is the fastest path to the right fix.
Hard Water Buildup
White, chalky deposits on everything -- faucets, shower heads, glass doors, inside pipes and water heaters. Calcium and magnesium restrict flow, kill efficiency, shorten appliance life. About 85% of US homes have hard water.
Low RO System Output
RO system filling slowly, weak trickle, or running out of water? Clogged pre-filters, worn membrane, low feed pressure, or waterlogged tank. Most fixes are filter replacements or pressure adjustments.
