Community Tips

WarningKasa Team

Never exceed 200 ppm (parts per million) chlorine concentration during well sanitization, as excessive bleach can damage well components and create health hazards; most residential wells require only 50-100 ppm for effective pathogen elimination.

TipKasa Team

Run the chlorinated water through every faucet, toilet, and fixture for at least 15 minutes each to ensure the sanitizer reaches all dead zones in the plumbing system where bacteria colonies thrive. Clorox Germicidal Bleach ($3-5 per gallon) is unscented and specifically formulated for water treatment without adding flavor or odor compounds that complicate post-flush testing.

Tool RecKasa Team

A basic water testing kit like the Hach Total Chlorine Test Strips ($15-25) is essential after sanitization to confirm residual chlorine levels have dropped below 0.2 ppm before resuming normal water use, preventing damage to appliances and eliminating taste issues that trigger unnecessary service calls. ---
