Toilet problems are some of the most common plumbing calls in any Fontana household, and many can be narrowed down before anyone arrives. A toilet that keeps refilling usually has a worn flapper or fill valve. Water on the floor around the base often points to a failed wax ring or loose closet bolts. A toilet that clogs over and over may have a partial blockage in the trap or a drain line problem further down.
Hard water in the Inland Empire can leave mineral deposits on fill valves, flappers and the rim jets that rinse the bowl, which leads to weak flushes and parts wearing out sooner. If your toilet runs on and off by itself, that is worth fixing quickly, since a running toilet can waste a lot of water and push up your bill.
If water is rising toward the rim, turn the shutoff valve behind the toilet clockwise to stop it. If the valve is stuck, lift the tank lid and raise the float to stop the fill. When several fixtures in the house back up together, mention it, since that suggests a main line issue rather than the toilet itself. For general guidance see our California toilet repair page.

The toilet problems Californians call about most
- A toilet that runs or refills on its own: usually a worn flapper, a misadjusted float or a failing fill valve. A running toilet can waste a large amount of water, which matters in a state that regularly faces drought restrictions.
- Weak or incomplete flushes: often mineral deposits blocking the rim holes and siphon jet, a common issue in hard water areas.
- Frequent clogs: wipes, excess paper, or a partial blockage further down the drain line.
- Water at the base: a failed wax ring, loose closet bolts, a cracked bowl or condensation on the tank in humid weather.
- A rocking toilet: loose bolts or a damaged flange, which can lead to a base leak if ignored.
Hard water and toilet parts
Much of Southern California and the Inland Empire has hard water. Minerals build up on flappers, fill valves and the small rim jets that direct water into the bowl. The result is a toilet that runs intermittently or flushes weakly even though nothing is broken. Cleaning mineral deposits and replacing worn rubber parts often restores performance. If the bowl stains quickly and the flush keeps getting weaker, scale is a likely cause.
