About Franktown
Franktown is a small unincorporated ranching and farming community at the junction of State Highways 83 and 86, about 7 miles east of Castle Rock and 9 miles south of Parker, near Castlewood Canyon State Park. It has kept a distinctly rural identity. We did not find a verified water or sewer provider for Franktown homes in the sources reviewed, so this page does not name one. If you receive a water bill, it shows your provider, and that provider's annual water quality report should include hardness. If you do not get a bill, your home may rely on its own well.
Choosing treatment once you know your water
| Finding | Common choice | Notes |
|---|---|---|
| Hardness above about 120 ppm | Water softener | Size from the reading and household use |
| Iron or manganese present | Dedicated filter first | Protects the softener's resin |
| Sediment or grit | Sediment prefilter | Change cartridges on schedule |
| Bacteria | Disinfection and well repair | Retest after treatment |
| Low hardness, no other issues | No softener | Consider a filter for taste only |
Signs to watch
- White scale on faucets, showerheads and the kettle
- Orange, brown or black stains in sinks and toilets
- Rumbling or popping from the water heater
- Changes in taste or odor
- Pressure dropping at several fixtures
Timing and practical notes
Test before you buy, and if you are on a well, test again after any pump or well work. Results from a certified lab are more complete than a quick strip test, and they give the plumber what they need to size equipment properly. A softener on a home not on municipal sewer sends regeneration water into the private onsite system, so a demand-based valve that regenerates only when needed is worth the small extra cost. Keep equipment in heated space, since open country east of Castle Rock sees hard winter freezes. Franktown is unincorporated, so plumbing permits go through the Douglas County Building Division in Castle Rock, which issues a Mechanical/Plumbing permit for unincorporated areas. A plumber can confirm whether your softener installation needs one and file it as part of the job, so the work is inspected and on record if you sell the property later.
