Heise's Plumbing completed a professional
toilet dye test and
leak detection service for a homeowner in the
St. Francis Wood neighborhood of
San Francisco, CA. The customer contacted our office near the historic St. Francis Wood Fountain after noticing their toilet was running constantly and causing their utility bills to rise. Our licensed plumbing technician performed a detailed dye test, placing non-toxic colored tablets into the tank to confirm if water was seeping from the tank into the bowl. We diagnosed a degraded flush valve flapper that was failing to seal, alongside a malfunctioning fill valve assembly. Our team replaced the worn flapper, installed a high-quality fill valve, adjusted the float arm, and tested the toilet's flush cycle. After finishing the repairs, we verified the leak was resolved and confirmed the toilet was operating safely and efficiently. If you need professional leak detection,
toilet repair, or general
plumbing services, Heise's Plumbing provides expert solutions throughout San Francisco and the Peninsula.
