Why Knowing Your GPG Matters

GPG (Grains Per Gallon) is the industry standard for measuring water hardness. Anything over 10 GPG is considered "Very Hard" and can rapidly damage water heaters, appliances, and plumbing.

Most DFW cities sit between 10 and 17 GPG. Knowing your specific number helps us size your water softener correctly so you don't overspend on salt or undersize your system.

Why DFW Water Feels Harder Than It Used To

Drought Effect: Drought conditions can raise mineral concentration in surface water by reducing dilution in reservoirs. In North Texas, this can result in periodic increases in hardness (calcium and magnesium), especially during extended dry cycles.

🪨 Why is it Naturally Hard?

  • Source: Water comes primarily from surface lakes (Lavon, Lewisville, Ray Hubbard).
  • Geology: Regional limestone geology contributes calcium and magnesium.
  • Result: Many homes experience "hard" to "very hard" water (often 8 — 18 GPG).

🧪 Why Does it Taste Chemical?

  • Disinfectant: Most DFW cities disinfect using chloramine (chlorine + ammonia).
  • Challenge: Chloramine is more stable but harder to remove than chlorine.
  • Solution: Basic filters are often ineffective. Catalytic carbon systems are required for full reduction.
