- Hardness grains-per-gallon and TDS reading
- Iron, manganese, sulfur, or PFAS presence
- Household size and peak flow rate
- System grain capacity (32k / 48k / 64k / 80k)
- Whether you add a drinking-water RO at the kitchen sink
- Drain availability for backwash and brine

- Schedule in the off-season (late fall through winter for most exterior trades).
- Bundle related work (e.g., gutters with roof, or HVAC with electrical) for a single mobilization fee.
- Check eligibility for the federal Energy Efficient Home Improvement Credit (up to $1,200/year) or the 30% Residential Clean Energy Credit.
- Avoid the cheapest quote — in our network it's a strong predictor of change-orders later.
When NOT to skimp
Some line items are tempting to cut and almost always cost more later: full tear-off vs. overlay on roofs, Manual J load calcs on HVAC, full-frame vs. insert on rotting window openings, and waterproofing/membrane work in bath remodels. If a contractor offers to skip any of these to "save money," get a second opinion.

Frequently Asked Questions
How hard is Nashville water?
Nashville Metro water from Metro Water Services averages 5–7 grains per gallon (moderately hard). Williamson and Rutherford County municipal supply runs 6–10 gpg. Private wells across Middle TN commonly test at 12–20 gpg, sometimes higher.
Do I need a water softener in Nashville?
If you have city water under 7 gpg, you may not — appliance lifespan won't suffer dramatically. Above 7 gpg, a softener pays back through extended water-heater, dishwasher, and washing-machine life plus less soap use. Well-water households almost always benefit.
How much does a whole-home water softener cost installed?
A typical 48,000-grain dual-tank softener installed in Nashville runs $2,200 to $3,800 in 2026, including bypass valve, brine tank, and plumbing tie-in. Premium metered units run $4,000 to $4,500.
What about PFAS (forever chemicals) in Tennessee water?
TDEC sampling in 2024 detected PFAS above the new EPA limit in several Middle TN municipal supplies. Point-of-use activated-carbon filters or RO systems remove the most common PFAS compounds; whole-home solutions exist but cost $3,500 to $9,000.
Reverse osmosis or whole-home filtration?
RO removes the most contaminants including TDS, fluoride, lead, PFAS, but only at one tap (typically the kitchen). Whole-home filtration treats chlorine, sediment, and taste at every fixture but does not reach RO levels of purity. Most Nashville households benefit from both.
