Summary:
Turn Off the Water Supply to Stop the Leak Immediately
The fastest way to stop any faucet leak is cutting off its water source. Look under your sink for two shut-off valves—one for hot water, one for cold. Turn them clockwise until they stop.
If you can’t find individual valves or they won’t budge, you’ll need to shut off water to your entire home. The main shut-off valve is typically near where the water line enters your house, often in the basement, garage, or outside near the meter.
Once the water is off, turn on the faucet to drain any remaining water from the lines. This immediately stops the leak and gives you time to assess the situation or wait for professional help.
What to Do When You Can't Access Shut-Off Valves
Sometimes shut-off valves are painted over, corroded, or hidden behind cabinets and pipes. In older San Francisco homes, these valves might not have been touched in decades and could break if forced.
If individual valves won’t turn or you can’t locate them, don’t force anything. Broken valves create bigger problems than the original leak. Instead, go straight to your main water shut-off. Yes, this means no water throughout your house, but it’s better than flooding or a burst valve.
Call your plumber immediately in this situation. We have the tools and experience to safely free stuck valves or install new ones. Many San Francisco plumbing contractors offer same-day service for these exact scenarios.
In apartment buildings, you might need to contact your building manager to access the main shut-off. Keep their emergency number handy—these situations always seem to happen at the worst times.
While waiting, place buckets or towels around the leak area to protect your floors and cabinets. Document the problem with photos for your plumber and, if necessary, your insurance company.

When Temporary Fixes Aren't Enough for San Francisco Homes
Some faucet problems can’t be temporarily fixed, especially in San Francisco’s older homes with aging plumbing systems. If water continues leaking after you’ve shut off the supply valves, you likely have a more serious issue.
Leaks behind walls, under sinks, or from supply lines require immediate professional attention. These aren’t DIY situations—they can cause significant water damage quickly in our city’s closely-packed housing.
Similarly, if your temporary fix fails within hours or you notice water pressure problems throughout your home, it’s time to call a professional plumber immediately.
Signs You Need Emergency Plumbing Service Right Away
Certain situations move beyond “temporary fix” territory into emergency plumbing calls. Water spraying from connections, multiple fixtures failing simultaneously, or any leak you can’t control with shut-off valves needs immediate professional attention.
If you smell gas near your faucet (some older homes have gas-heated water lines nearby), evacuate immediately and call both your gas company and an emergency plumber. Never attempt repairs when gas is involved.
Water appearing in unexpected places—like dripping from light fixtures, spreading across floors, or showing up in rooms below your leak—indicates the problem has spread beyond the faucet itself. Your pipes, walls, or flooring might be compromised.
San Francisco’s emergency plumbing contractors typically charge premium rates for after-hours calls, but water damage repairs cost far more than emergency service fees. A small leak can cause thousands in damage within hours if it reaches electrical systems, hardwood floors, or structural elements.
Don’t wait if you see water stains spreading, hear water running when all fixtures are off, or notice your water meter spinning when no water is being used. These signs indicate leaks that temporary fixes cannot address.
Why Professional Plumber Diagnosis Matters for Permanent Solutions
Even successful temporary fixes mask underlying problems that will resurface. Professional plumbers don’t just replace worn washers—we diagnose why components failed prematurely and address root causes.
In San Francisco’s older homes, faucet leaks often indicate broader plumbing issues. Mineral buildup from our hard water, aging pipes, or incorrect water pressure can cause repeated failures. A licensed plumbing contractor examines your entire system, not just the obvious problem.
Professional diagnosis also reveals when replacement makes more financial sense than repeated repairs. Older faucets with discontinued parts might need multiple service calls, while a new fixture provides years of trouble-free operation.
Quality plumbing contractors offer warranties on our work—something no temporary fix can provide. We also ensure repairs meet local building codes and won’t cause insurance issues if problems develop later.
The investment in professional service pays for itself through water savings, prevented damage, and the peace of mind that comes with knowing the job was done right. Temporary fixes serve their purpose, but permanent solutions protect your home and your budget long-term.
Getting Professional Help for Lasting Faucet Repair in San Francisco
Temporary fixes can provide immediate relief from annoying drips and prevent water waste while you arrange professional service. However, they’re exactly what the name implies—temporary solutions that buy you time, not permanent repairs.
The key is knowing when to attempt a temporary fix and when to call for immediate professional help. Water damage happens quickly and costs far more than emergency plumbing service.
