Install an under-sink reverse osmosis system for the cleanest drinking water at home -- feed water connection, filter mounting, storage tank, drain saddle, dedicated faucet, and the critical initial flush.

Test your water with DIY strips, reagent kits, or certified lab analysis -- what to test for, how to collect samples, how to read results, and what treatment actually fixes common contaminants.

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.

Pick the right salt, fill the brine tank correctly, break up salt bridges, and keep your water softener running so you get consistent soft water without the scale and spotty dishes.

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.

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.

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.
