Leaking Toilet Base Repair in San Jose, CA
Water around the base typically means the wax ring has failed or the toilet has been rocking on a loose flange. On slab foundations, the flange often sits on concrete and can crack when bolts are overtightened. We pull the toilet, inspect the flange, install a repair ring or new flange if needed and reset the bowl on a new seal. We also check for soft flooring so you know if any water damage needs attention.

Leaky Toilet Repair in San Jose
A leaky toilet can waste hundreds of gallons of water annually, increasing your utility bills and potentially causing water damage. Our technicians in San Jose are experts at identifying the source of leaks, whether it's a cracked tank or bowl, a faulty wax ring, or a worn-out fill valve. We use specialized dyes and pressure tests to reliably locate hidden leaks and provide durable repairs, often involving the replacement of seals, gaskets, or the entire flushing mechanism. Ignoring a leak can lead to structural damage or mold growth, so prompt repair is crucial.
Leaking Toilet Repair in San Jose
Toilet leaks can cause serious water damage to your bathroom floor, subfloor, and even the ceiling below. Leaks can originate from the base of the toilet, the tank, or the supply line. Common culprits include a worn-out wax ring, loose bolts, or cracked porcelain. We carefully inspect all potential leak points, replacing seals, tightening connections, or recommending bowl replacement if the porcelain is damaged, preventing further water intrusion.
Brands We Service in San Jose, CA
FBL Plumbing is experienced in repairing toilets from all leading manufacturers commonly found in San Jose, CA homes and businesses. This includes popular brands like Kohler, American Standard, Toto, Delta, Eljer, and Gerber. Our plumbers are familiar with the specific designs and proprietary parts of these brands, allowing for accurate diagnosis and efficient repair. We stock a wide range of common replacement parts to ensure that most repairs can be completed on the first visit, regardless of your toilet's brand or model.
Fill Valve Replacement in San Jose
A noisy, slow or hissing tank often points to a worn fill valve. Mineral scale clogs the small ports inside, which causes long refill times and phantom refills in the night. We replace old ballcock valves with modern adjustable fill valves from Fluidmaster or Korky and set the water level to the manufacturer mark. The job takes about 20 minutes and makes an older toilet much quieter.
Running Toilet Fixes in San Jose
A toilet that constantly runs or refills itself intermittently is not only annoying but also a major water waste. This issue in San Jose is typically caused by a faulty flapper valve, an improperly adjusted float, a worn-out fill valve, or sediment buildup. Our technicians diagnose the specific component causing the problem and replace it with high-quality, long-lasting parts. We ensure proper alignment and adjustment of all internal mechanisms to restore your toilet's efficient operation and stop wasted water consumption.
Clogged Toilet Clearing in San Jose, CA
Stubborn toilet clogs are a frequent problem that can bring your bathroom to a halt. While some can be cleared with a plunger, deeper blockages may indicate issues further down the drain line or even in the main sewer line. Our technicians use professional-grade augers and sometimes even camera inspections to pinpoint and remove obstructions effectively. We handle everything from foreign objects to excessive toilet paper, ensuring your toilet drains freely again.

Clogged Toilet Solutions in San Jose, CA
Persistent toilet clogs are a common nuisance in San Jose, CA homes, often caused by non-flushable items or excessive toilet paper. While a plunger can clear minor blockages, persistent clogs indicate 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.

Yes, FBL Plumbing stands behind the quality of our work. We offer a warranty on both the parts we install and the labor performed during your toilet repair. The specific warranty details will be provided at the time of service, ensuring your peace of mind.
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.
Weak flushing can be caused by several issues, including insufficient water in the tank, a clogged rim jet, a partially closed stop valve, or a partial clog in the drain line. Our plumbers can diagnose the exact cause and restore full flushing power.
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, preventing potential water waste or damage.
