Westminster's water is moderately hard, about 112 to 149 ppm or 7 to 9 grains per gallon according to the city, which is right where many households start noticing scale. A softener can help, but a test and a clear goal should come first. Call the number on this page to be connected with a local plumber in Westminster.
Westminster's water at a glance
Standley Lake is the city's only water source, filled by Clear Creek snowmelt carried through canals. Water is treated at the Semper and Northwest facilities and disinfected with chloramines. The city's latest report lists total hardness of 112 to 149 ppm, roughly 7 to 9 grains per gallon. Housing here leans newer than Denver: the median home dates to 1987, with about a third built before 1980. That means most supply piping is copper rather than old galvanized steel, so the real targets for a softener are water heaters, dishwashers, faucet cartridges and glass shower doors. At 7 to 9 grains, scale builds steadily rather than overnight, which gives you time to test and plan instead of rushing a purchase.
What to do now
- Look at the symptom you care about. White crust and spotted glass point to hardness; a pool smell points to chloramines.
- Read Westminster's annual water quality report so you know the published range for your area.
- Have a plumber test hardness at the kitchen tap to confirm where you fall in that range.
- Decide which taps stay unsoftened: irrigation, hose bibs and possibly one drinking tap.
- Pick a location near the main with a drain, an outlet and room for a brine tank.
- If the home has a well or pond tied to plumbing, know that Westminster requires a backflow assembly on that auxiliary supply.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Chalky ring in the kettle | Calcium and magnesium in moderately hard water |
| Swimming-pool smell at the tap | Chloramine disinfection, which a softener does not remove |
| Water heater rumbling | Scale and sediment settled in the tank |
| Salty taste after a softener install | Valve set to the wrong hardness or regenerating too often |
| Softener using no salt for weeks | Salt bridge in the brine tank or a stuck valve |
What affects the cost
- Unit capacity matched to 7 to 9 grain water and your household
- Copper, PEX or older galvanized pipe at the tie-in point
- Drain routing and an air gap
- Optional catalytic carbon stage for chloramine
- Whether the work counts as a plumbing modification needing a city permit
Westminster's Building Division requires permits to modify plumbing systems, so the plumber can confirm whether your install needs one.
