This common issue is often caused by a faulty flapper, a misaligned fill valve, or an improperly adjusted float.

Clogged Toilet Solutions in San Francisco, CA
Stubborn toilet clogs are a common nuisance in San Francisco, CA homes, often caused by non-flushable items or excessive toilet paper. While a plunger can clear minor blockages, persistent clogs suggest a deeper issue in the trap, drain line, or even the main sewer line. Our plumbers utilize professional-grade augers and hydro-jetting equipment to safely and effectively clear even the toughest clogs without damaging your toilet or pipes. We also inspect for potential causes like root intrusion or pipe corrosion, which are sometimes seen in older homes.
Toilet Flush Mechanism Repair in San Francisco, CA
If your toilet isn't flushing properly, it could be due to issues with the flush chain, handle, flapper, or fill valve. A weak flush might mean the tank isn't filling correctly, while a loose handle might not be engaging the flapper. Our plumbers are skilled at diagnosing these internal tank problems, replacing worn or broken components like flush valves, fill valves, and toilet handles to restore full and effective flushing power.
Weak Flush and Clog Repair in San Francisco, CA
If your toilet needs two flushes or clogs often, the problem may be scale in the rim jets, a partial blockage in the trapway or a flush valve that does not open fully. We auger the trap, check the vent if gurgling is present and clean the jets with a descaling treatment. Some low-flow toilets from the 1990s simply flush poorly, and we will tell you honestly if replacement is the better fix.
Toilet Tank and Bowl Crack Repair in San Francisco
Cracks in a toilet tank or bowl in San Francisco can lead to serious water leakage and require immediate attention. While small hairline cracks might be temporarily sealed, larger or structural cracks often necessitate replacement of the affected component. Our technicians assess the severity of the crack and advise on the most cost-effective and durable solution. We can perform precise tank or bowl replacements, ensuring a watertight seal and proper function, preventing further water damage to your flooring or subfloor.

Cracked Tank and Supply Line Repair in San Francisco, CA
A hairline crack in the tank or a bulging braided supply line can let go without warning and flood a bathroom. We inspect the tank, tank-to-bowl bolts and gasket, and the supply line during every visit. If the porcelain is cracked we will price a replacement tank or new toilet, and we upgrade old plastic or vinyl supply lines to braided stainless.

Frequently Asked Questions About Toilet Repair in San Francisco
Most simple toilet repairs, like a new flapper or fill valve, run roughly $125 to $275 including parts and labor. Resetting a toilet on a new wax ring is typically $175 to $350, and flange repairs can bring the total to $300 to $500. We give you a firm price before starting.
Yes, FBL Plumbing stands behind all our toilet repair work in San Francisco, CA with a full warranty on parts and labor. We want you to feel confident in the durability and quality of our repairs. Specific warranty details will be provided at the time of service.
While some minor running toilet issues, like a simple flapper adjustment, can be DIY, more complex problems may require a professional. If you're unsure about the cause, or if the issue persists after basic troubleshooting, calling FBL Plumbing ensures an accurate diagnosis and lasting repair, avoiding potential water waste or damage.
While some minor issues like a simple flapper replacement can be a DIY fix, many toilet repairs, especially those involving the internal mechanisms, drain lines, or significant leaks, are best left to professionals. Incorrect repairs can lead to greater damage, water leaks, or code violations.
Hard water leaves calcium and magnesium deposits on flush valve seats, fill valve ports and rim jets. Over time this causes leaks, slow refills and weak flushes. Descaling and choosing parts made to resist scale help repairs last longer.
Most flapper, fill valve and supply line repairs take 20 to 45 minutes. Pulling and resetting a toilet usually takes about an hour, and flange repairs can add another 30 to 60 minutes.
Most standard toilet repairs, such as fixing a running toilet or replacing internal tank components, can be completed within 1 to 2 hours. More complex issues like clearing a tough main line clog or replacing a wax ring might take longer, potentially 2 to 4 hours.
Common signs include a toilet that runs nonstop, a weak or incomplete flush, water leaking around the base, a rocking or unstable bowl, or a visible crack in the porcelain. Any unusual noises, like gurgling or whistling, can also point to an internal issue that needs attention.
