A toilet that runs intermittently through the night, rocks when seated, or fails to flush properly is more than an annoyance—it can silently waste thousands of gallons of water and rot the subfloor beneath your bathroom tile. In Upland homes, mineral-rich water degrades rubber flappers and fill valves within three to five years, while seismic vibration and settling can break floor flange bolts and break the wax seal. Our plumbers rebuild running toilets, repair rotted closet flanges, and install high-performance, water-saving commodes.
If you hear your toilet suddenly refill for five seconds in the middle of the night, your toilet has a phantom flush. This occurs when the rubber flapper or flush tower seal no longer seats tightly against the flush valve opening, allowing water to trickle into the bowl until the float drops and triggers the fill valve. We install heavy-duty chemical-resistant flappers and anti-siphon fill valves that resist hard-water mineral attack.
A toilet should never rock or shift when you sit down. Movement indicates that the floor closet bolts have loosened or the underlying cast-iron or PVC flange has cracked. Once a toilet shifts, the wax seal between the porcelain horn and the sewer pipe shears apart. Every subsequent flush forces moisture and sewer gas beneath the bathroom flooring, rotting wood subfloors and tile underlayment. We pull the toilet, inspect the subfloor, reconstruct broken flanges with stainless steel repair rings, and reset the unit on a heavy-duty reinforced wax seal.
Older toilets installed before 1994 consume 3.5 to 5.0 gallons per flush. Upgrading to a modern high-performance commode reduces consumption to 1.28 gallons per flush (GPF) or 1.1 GPF, saving an average family thousands of gallons annually while delivering superior bulk waste clearing. We install chair-height (comfort height) elongated models from industry leaders like Toto, Kohler, and Gerber.
Unaddressed plumbing wear damages building materials, increases water waste, and risks sudden structural failures.
We install durable, commercial-grade materials designed for long-term reliability in the Cucamonga Valley.
A rocking toilet indicates that the closet bolts securing the commode to the floor have loosened, the floor itself is uneven, or the underlying closet flange has cracked. Rocking breaks the watertight wax seal and must be repaired immediately to prevent subfloor water rot.
