Toilet Repair and Installation in San Francisco

Heise's Plumbing provides professional toilet repair and installation services in San Francisco, CA. Running toilets can waste thousands of gallons of water and increase your utility bills, while leaking toilet bases can rot floorboards. From simple flapper and fill valve replacements to installing modern, low-flow Toto and Kohler toilets, our licensed plumbers ensure your bathroom fixtures function reliably.

Common Problems We Resolve

• Constant running water from worn flappers or fill valves.
• Water pooling around the base indicating a degraded wax ring seal.
• Stubborn clogs in the toilet trap that household plungers cannot clear.

How We Diagnose & Solve the Issue

Inspection & Diagnosis: We perform dye tests to detect internal valve leaks, inspect the floor bolts and flange for decay, and verify flush power efficiency.

Our Service Process: We replace worn internal hardware, install new wax rings and bolts, seal the bowl base, or install a new high-efficiency toilet, testing the system for smooth, leak-free operation.
