An Upland toilet that runs, leaks or clogs usually needs a new flapper or fill valve, a fresh seal at the floor, or a clog cleared from the trap. Upland's water is mostly local groundwater, and mineral buildup in tank parts is a common reason they stop sealing. Call the number on this page to be connected with a local plumber in Upland.

When a toilet needs a plumber
- You hear the tank refill when nobody has used it
- The water level creeps up to the overflow tube
- The flush starts strong and then fades
- Water seeps from under the bowl or from the supply connection
- Bolts at the base are rusted or the bowl moves
- A plunger only works some of the time
What is local about Upland toilets
The City of Upland provides water through Public Works. By the City's account, about 80 percent of customer demand is met with local groundwater from City wells and from the San Antonio and West End Consolidated water companies, drawing on the Chino, Cucamonga and Six Basins. San Antonio Canyon surface water and imported State Water Project water make up the rest. Groundwater in this part of the Inland Empire tends to be hard, and in a toilet that shows up as crust on the fill valve and the flapper seat, plus narrowed rim holes that weaken the rinse. The City's water quality report has the current mineral readings if you want them.
The City handles leaks on its side of the system and maintains its water meters. Inside the property line, the toilet and the plumbing feeding it are the owner's to repair. For a water leak on the City side, Public Works lists (909) 291-2930, and after-hours mainline leaks go to Upland Police Dispatch at (909) 946-7624.
What affects the price
- The failed part: a flapper swap is short work; a wax seal means draining and lifting the bowl.
- Mineral wear: scaled tank parts are usually replaced together.
- Hardware at the floor: corroded closet bolts or a broken flange add time.
- Shutoff valve: an old valve that will not close may need replacing first.
- Clog location: the trap is quick; a blockage farther down may need a drain machine.
- Hour of the call: nights and weekends cost more.
After you dial
An independent plumber who serves Upland picks up the call. Describe the symptom, how long it has been going on and whether water has reached the floor or a ceiling below. If the plumber recommends a new toilet and a permit is needed, the City of Upland Building and Safety Division takes permit requests online through its Citizen Self Service portal.
