Common Problems

Toilet Keeps Running

One of the biggest water wasters in a home. Water flows continuously into the bowl or overflows inside the tank. Worn flapper, faulty fill valve, or float set too high. 200+ gallons per day wasted.
Toilet Won't Flush Properly

Weak flush, incomplete, or multiple flushes to clear? Tank water level too low, clogged rim holes, flapper closing too fast, or partial clog in the trap or drain.
Toilet Leaking at Base

Water pooling at the base usually means a failed wax ring. Left unaddressed: sewer gas in the home, subfloor rot, mold, and structural damage beneath the floor.
Phantom Flushing

Toilet refills on its own without anyone flushing? Tank is silently leaking into the bowl through a worn flapper. Water level drops, fill valve kicks on. Wastes hundreds of gallons per month. One of the easiest toilet repairs.
