In a Chino Hills plumbing emergency, close the main, and if you smell gas, leave and call 911 and SoCalGas at 1-800-427-2200. For City water or sewer emergencies after 4:45 p.m. and on weekends, the City lists (909) 364-2860. For leaks and backups on your property, call the number on this page to be connected with a local plumber in Chino Hills.

When you call the number
Calling connects you with an independent plumber who serves Chino Hills. Have the address ready, describe what is leaking or backing up, and say whether the main is off. If you can tell whether the problem started suddenly or has been building, mention it. Ask how after-hours pricing works before the plumber heads over. Arrival depends on the time of day and the plumber's schedule, so no arrival time is promised.
What determines the price
- Hour. Late-night and weekend work typically costs more than weekday service.
- Extent of damage. One leaking fitting is very different from a burst line inside a ceiling.
- Access. Hillside lots, long yard runs and finished walls can add labor.
- Permitted work. The City fee schedule lists plumbing permits for water heaters, onsite water supply lines, sewer lines and residential re-pipes under Building Services, so a replacement may include one.
Chino Hills water and sewer
The City of Chino Hills provides both water and sewer service, which simplifies the question of whom to call when something fails in the street. A few properties are sewer-only accounts with the City and get their water from a separate agency, so check your bill if you are unsure. The City adds a pass-through fee set by the Inland Empire Utilities Agency to each sewer account, reflecting the regional role in wastewater.
During business hours, Public Works is at (909) 364-2800. After 4:45 p.m. and on weekends, the City lists (909) 364-2860 for water and sewer emergencies. Use those numbers for a main break, water flowing down the street or a sewer overflow in the road; a backup or leak confined to your home is a plumbing job. The City disinfects its water with chloramine, and its service line inventory found no lead service lines in its service area. Where household pressure runs high, a worn pressure regulator can strain supply hoses and water heater valves, so it is worth having checked during the visit.
Checklist before help arrives
- Close the main shutoff and open a lower faucet
- Switch off a leaking water heater at the gas valve or breaker
- Avoid using water during a drain backup
- Unlock the gate and clear access to the cleanout
