Our research didn't identify a water provider or a backflow program for Franktown, so the rules depend on who supplies your water, which your bill or Douglas County can confirm. If you need a device added, repaired or checked, call the number on this page to be connected with a local plumber in Franktown.

What's known in Franktown
Franktown is a small unincorporated ranching and farming community where State Highways 83 and 86 meet, about seven miles east of Castle Rock and nine miles south of Parker. It has kept a distinctly rural identity. Our fact sheet doesn't name a water provider for Franktown or a backflow testing program, so we can't tell you what schedule applies, if any.
That leaves two practical points. First, look at your water bill: if a district or utility serves you, it sets the backflow rules, and you can ask it directly. If there's no bill, your property may have its own water supply, and any backflow protection is about keeping that supply clean. Second, plumbing permits for unincorporated Franktown go through the Douglas County Building Division at 100 Third Street in Castle Rock (303-660-7497), which offers a mechanical and plumbing permit.
Rural properties have more ways for backflow to happen: stock tanks, hydrants, sprayers and irrigation all connect to drinking water lines. Each of those is worth protecting whether or not anyone requires a test.
Matching the device to the connection
| Connection | Hazard level | Typical device |

| Garden hose | Low to moderate | Hose bib vacuum breaker |
| Lawn sprinklers | Moderate | Pressure vacuum breaker |
| Stock tank or pond fill | Moderate to high | Air gap or RP assembly |
| Chemical sprayer fill | High | RP assembly or air gap |
Signs you need help
- Hoses regularly sit in troughs or tanks
- A yard hydrant leaks or won't drain
- A sprinkler device spits water at start-up
- You're adding outbuildings with water service
- Freeze damage on any outdoor device
Seasonal notes
Open country near Castlewood Canyon gets hard winters. Disconnect hoses, drain sprinkler devices and make sure hydrants drain properly before the first freeze. In spring, check every outdoor connection before turning water back on to tanks and lawns.
When you call, describe each place water leaves the house: spigots, hydrants, tank fills, sprinklers and any barn or shop lines. A plumber can tell you which connections need a device and which type fits. If you do find that a provider serves you, ask it whether it requires testing and where reports go, then keep that answer with your property records.
