Total Dissolved Solids

Measure mineral content and overall water purity. WHO safe limit: 500 ppm.

0-50: Ultra Pure 50-300: Excellent 300-500: Fair 500+: Poor

Acidity / Alkalinity

Analyze water acidity. Safe range: 6.5–8.5. Below causes corrosion, above causes scale.

< 6.5: Acidic 6.5-8.5: Ideal > 8.5: Alkaline

Calcium & Magnesium

Determine if you need a water softener. Hard water damages appliances and dry skin.

< 60: Soft 60-120: Ideal 120-180: Hard > 180: Very Hard

Liters / Gallons per Min

Measure faucet/shower flow rate. Check against WaterSense efficiency standards.

≤ 1.8 GPM: Efficient > 2.5 GPM: Wasteful

Disinfection Level

Check free chlorine disinfection levels. EPA limit: 4 ppm. Ideal: 0.2–1.0 ppm.

< 0.2: Insufficient 0.2-1.0: Ideal > 4.0: Exceeds Limit
