What causes toilet problems?

Common causes include worn-out parts like flappers, fill valves, or seals, hard water buildup inside the tank or pipes, poor flushing power due to blockages or outdated design, hidden leaks that waste water and weaken floors, and improper installation or aging plumbing systems.

Why is my toilet constantly running?

A constantly running toilet is usually caused by a worn flapper that doesn't seal properly, a faulty fill valve, or an improperly adjusted float. This can waste hundreds of gallons of water monthly and significantly increase your water bills.

Do you offer same-day toilet repair?

Yes, Precision Flow Plumbing offers same-day toilet repair service throughout San Francisco. We also provide 24/7 availability for urgent toilet emergencies like overflows and major leaks.

Should I repair or replace my toilet?

Minor issues like running toilets, worn flappers, or faulty fill valves are usually worth repairing. However, if your toilet has cracks, requires frequent repairs, or is an older water-wasting model, replacement with a modern water-efficient toilet may be more cost-effective.

How much water does a leaking toilet waste?

A running or leaking toilet can waste hundreds of gallons of water every month, leading to significantly higher utility bills. Quick professional repair protects both your home and your wallet.
