In a Castle Rock plumbing emergency, close the main valve, and if you smell gas, leave and call 911 and Black Hills Energy, using the number on your gas bill. Then call the number on this page to be connected with a local plumber in Castle Rock.
Castle Rock runs its own utility, Castle Rock Water, with the Plum Creek Water Purification Facility as its main plant. Some homes with a Castle Rock mailing address, such as in The Village at Castle Pines, are served by other districts, so check the name on your water bill. Natural gas in town comes from Black Hills Energy, not Xcel.
What to do right now
- Stop the water. Close the main valve where the line enters the house. If water is running in the street, report it to Castle Rock Water at 720-733-6000 and press 1 after hours.
- Cut power near the leak. Turn off breakers for wet outlets or appliances if you can reach the panel safely.
- Isolate the water heater. If the tank is leaking, close its cold inlet and turn the gas control off.
- Hold off on drains. During a sewer backup, every flush adds to the overflow.
- If there is a gas smell, get out. From outside, call 911 and Black Hills Energy at the number printed on your bill.
- Photograph the damage before you start cleanup.
Common symptoms and their usual causes
| Symptom | Likely cause |
|---|---|
| Rumbling, then a puddle under the water heater | Sediment and scale wearing out the tank |
| Water stain spreading on a ceiling | Leaking supply line, drain joint or toilet seal above |
| Gurgling toilet with water rising in a tub | Blockage in the main house drain or sewer line |
| Wet ground near the street | Service line or main leak; call Castle Rock Water |
| No water on a sub-freezing morning | A frozen pipe in an exterior wall, garage or crawl space |
What affects the cost
Night, weekend and holiday calls generally cost more. Access is the next factor: a pipe in an unfinished basement is faster to repair than one behind drywall or tile. Water heaters deserve a mention here, because Castle Rock Water describes its water as moderately hard to hard, roughly 6.6 to 10.8 grains per gallon, and scale shortens tank life. Castle Rock Water does not recommend softeners because of the salt they add to wastewater, so ask the plumber about flushing the tank as part of routine care. For a replacement, the plumber can confirm what the Town of Castle Rock building department requires. No arrival time is promised.
