Most Castle Rock homes are on Castle Rock Water, so a hidden leak tends to show up as rising usage, a meter that moves with everything off, or soggy ground with no sprinkler running. A plumber can confirm the leak and locate it before anyone digs. Call the number on this page to be connected with a local plumber in Castle Rock.
A quick look at Castle Rock
Castle Rock is the Douglas County seat, a large and growing town along I-25. Its water comes from Castle Rock Water, which relies mostly on deep Denver Basin groundwater plus renewable supplies, and the town reports its water as moderately hard to hard. Some addresses with a Castle Rock mailing address, such as The Village at Castle Pines, are served by other districts, so check whose name is on your bill.
What to do now
- Turn off the sprinkler controller and every faucet and appliance in the house.
- Check the meter, then check it again after an hour of no use. A change means water is escaping.
- Test toilets with a few drops of food coloring in each tank.
- Close the main shutoff if water is visibly pooling or spraying.
- If water is coming up in the street, report it to Castle Rock Water at 720-733-6000; after hours, press 1.
- Note when the problem started and take photos of stains or wet areas.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Meter moves with the house shut down | A leak somewhere past the meter |
| Wet strip of lawn from the street toward the house | Break in the buried service line |
| One irrigation zone that never dries | Cracked lateral line or a valve that will not close |
| Crusty white buildup on a valve or fitting | Slow drip leaving hard-water minerals behind |
| Damp drywall under a bathroom | Shower valve, drain joint or supply line |
| Warm patch on a tile floor | Hot water line leaking under the slab |
Cost factors
- How many sections of plumbing need to be isolated and tested
- Whether the leak sits under a slab, inside a finished basement, in a wall or in the yard
- Equipment used to pinpoint it, such as acoustic or thermal tools
- Hard-water scale on valves, which can make shutoffs harder to work and add parts to the repair
- The repair itself and any Town of Castle Rock building permit it requires
For irrigation leaks, keep in mind that Castle Rock requires a mechanical backflow device on residential underground lawn irrigation. Annual testing is not listed as required for homes, but the town recommends periodic testing, and a repair visit is a good time for it.
