Water Testing Service Plano TX | Hardness, PFAS, pH, Iron

In-home water quality testing in Plano runs $150–$300 and measures hardness, pH, iron, chlorine, total dissolved solids, and water pressure — the parameters that drive whether you need a softener, a reverse osmosis system, or no treatment at all. Staggs Plumbing tests the water before recommending treatment, so you're not buying equipment based on someone else's guess.

What’s Actually in Plano Tap Water

Plano’s municipal water comes primarily from the North Texas Municipal Water District (NTMWD), drawing from Lake Lavon, Lake Tawakoni, and Lake Texoma. The water meets all federal safety standards. But “meets federal standards” doesn’t mean it’s optimal for your plumbing, appliances, or daily comfort.

Hardness: 15–20 grains per gallon (moderately hard) — 2–3 times the national average. Builds scale on faucets, showerheads, water heaters, and dishwashers. Reduces soap effectiveness. Cuts water heater lifespan by 30–40%.

Chlorine and chloramine: Used by NTMWD as the primary disinfectant. Affects taste and smell. Hard on rubber seals in appliances over time.

TDS: 200–400 ppm: Drinkable, but noticeable on taste tests against filtered water.

PFAS (“Forever Chemicals”): Detected in NTMWD source water under EPA UCMR 5 monitoring. EPA’s finalized limits take effect with full utility compliance required by 2029.

When You Should Have Your Water Tested

Before installing a water softener: Sizing a softener correctly requires knowing your actual hardness — not the city average, but your tap.

After buying a home: Testing tells you the baseline before you start making decisions.

When you notice symptoms: White scale buildup, cloudy glassware, dry skin after showers, soap that won’t lather, rust-colored water, higher energy bills.

Before major equipment upgrades: Water chemistry affects equipment life.

What Our In-Home Water Test Measures

Parameter	What It Tells You
Hardness (GPG)	Drives water softener sizing and confirms scaling risk
pH	Affects pipe corrosion rates and treatment system effectiveness
Iron (ppm)	Source of staining and taste issues; indicates pipe condition
Chlorine / chloramine	Baseline for filtration system sizing
Total Dissolved Solids (TDS)	Overall mineral content; baseline for RO performance
Water pressure (PSI)	Diagnostic for fixture wear and PRV operation

FAQ

Water Testing Service Plano TX | Hardness, PFAS, pH, Iron — Common Questions

Straight answers before you call.

How hard is Plano tap water?

Moderately hard — typically 15–20 grains per gallon, 2–3 times the national average. Hardness varies slightly by neighborhood depending on which NTMWD treatment facility serves the area.

How much does water testing cost in Plano?

Professional in-home water testing runs $150–$300. Includes hardness, pH, iron, chlorine, TDS, and water pressure measurements with written report and treatment recommendations.

What's in Plano tap water?

NTMWD water contains chloramine for disinfection, total dissolved solids in the 200–400 ppm range, low levels of PFAS compounds detected through EPA UCMR 5 monitoring, moderately hard water (15–20 GPG), and typical surface-water mineral content. The water meets all federal safety standards but is hard on plumbing and appliances.

Is there PFAS in Plano water?

Low levels of PFAS compounds have been detected in NTMWD source water under EPA UCMR 5 monitoring. Concentrations are below imminent-emergency thresholds but above EPA's finalized 4 ppt enforceable limits for PFOA and PFOS. Full utility compliance is required by 2029. An under-sink reverse osmosis system reduces PFAS in drinking water to undetectable levels.

Should I get a water softener in Plano?

For most Plano homes, yes. At 15–20 GPG hardness, savings on water heater lifespan, fixture replacement, soap and detergent use, and skin/hair care typically pay back a softener within 3–5 years for a family of 3 or more. Test first to confirm your specific hardness, then decide.
