In Chino Hills, a sump pump usually handles water from a sloped lot, a retaining wall subdrain or a room below grade, since most homes have no basement. Common failures are a stuck float, a bad check valve, power loss or a worn motor. Call the number on this page to be connected with a local plumber in Chino Hills.

What happens when you call
Calling the number on this page connects you with an independent plumber who covers Chino Hills. Be ready to describe the pit's location, what feeds it, and whether the pump is silent, humming or cycling. A plumber on site typically tests power, lifts the float, watches a run cycle, checks the check valve and follows the discharge pipe to where it ends. On a sloped property, that often means walking a long run down the yard.
If the problem is the drain feeding the pit rather than the pump, they will tell you that too.
What drives the cost
- Repairing a float, switch or valve compared with a full replacement
- Sump pump or sewage ejector
- Pipe length and vertical lift, which can be significant on a hillside lot
- Basin condition and access
- Battery backup or alarm
- Permits through City of Chino Hills Building Services, whose fee schedule lists plumbing items such as sewer line installation and repair
Chino Hills conditions
The City of Chino Hills provides water and sewer service, and a pass-through fee set by the Inland Empire Utilities Agency is added to each sewer account. Some properties have sewer-only accounts with the City and get water from another agency, so check your bill if you are not sure. Either way, the City's sewer handles household wastewater; storm runoff from a pump should go outdoors.
The City lists (909) 364-2860 for water or sewer emergencies after 4:45 p.m. and on weekends. That is useful if an ejector backup turns out to be a problem in the City's line rather than yours.
Pumps on hillside lots tend to run only during heavy winter storms, so they can go a long time without anyone noticing a stuck float or a clogged intake. Where the discharge empties also matters on a slope: water released at the top of a bank can soften soil or undercut landscaping further down, so a plumber may suggest extending the line or moving its outlet.
Checklist before the plumber arrives
- Shut off the pump circuit if water is near it
- Note where the discharge exits and whether it is blocked
- Clear leaves and debris from any yard drain that feeds the pit
- Look for wet spots or erosion along the slope below the discharge outlet
- Have your water and sewer bill handy
- Keep children and pets away from the pit
