Plumbing emergencies always feel like they happen at the worst possible moment — late at night, right before work, or when guests are over. The good news: acting fast can dramatically reduce damage, cleanup time, and repair cost.
At Peninsula Plumbing Solutions, we help homeowners across San Carlos, Belmont, Redwood City, and San Mateo with same-day and emergency plumbing service. Here’s exactly what to do the moment something goes wrong.
Shut Off the Water — Fast
A. Main Water Shut-Off (Most Important)
In a typical Peninsula home (San Carlos, Redwood City, Belmont):
- The main shut-off is usually on the side of the house, near the front hose bib.
- Newer homes: look for a ball-valve with a yellow handle.
- Older homes: may have a gate valve.
How to shut it off:
Turn the valve clockwise until it stops. This cuts water to the entire house.
B. Fixture-Level Shut-Offs
If the issue is isolated (toilet, sink, water heater), you can shut off water just to that area:
- Toilet — valve behind the bowl
- Sink — valves under the cabinet
- Water heater — valve on top of the unit
- Washing machine — hot & cold hoses behind the machine
What to Do for Common Plumbing Emergencies
Overflowing Toilet
- Don’t flush again
- Turn the valve behind the toilet
- Remove the tank lid and push down the flapper if needed
- Use towels to block water from spreading
Burst Pipe
- Shut off main water immediately
- Open faucets to relieve pressure
- Place a bucket under drips
- If flooding is near electrical outlets, leave the home and call 911
Major Leak Under a Sink
- Shut the fixture valve
- Clear items under the sink
- Put towels and a bucket under the trap
- Avoid using the sink until repaired
Water Heater Leaking
- Shut off the water at the heater
- If you smell gas, leave and call PG&E
- Do not relight anything
When a Plumbing Emergency is Dangerous (Leave the House or Call 911)
Leave immediately if you see:
- Water rising near electrical outlets
- A ceiling that looks like it may collapse
- Water spraying near your electrical panel
- A strong gas smell around the water heater
Your safety comes first — plumbing can be repaired, people can’t be replaced.
What Not to Do During a Plumbing Emergency
❌ Don’t Use Chemical Drain Cleaners
Older San Carlos homes have cast-iron or galvanized piping — chemical cleaners can eat the metal, crack the pipe, or make the clog worse.
❌ Don’t Keep Running Water Into a Blocked Drain
This turns a small clog into a full-on backup.
❌ Don’t Ignore Small Leaks
Small drips under a sink often mean the joint is failing — and sudden failure causes thousands in damage.
❌ Don’t Try to DIY Pressurized Lines
Burst pipes, main lines, and valves require proper tools and safety.
When You Need a Professional Plumber (No Exceptions)
Call a licensed plumber ASAP for:
- No water to the entire house
- Repeated clogs (could be tree roots or collapsed pipe)
- Sewer backing up into tubs or showers
- Water heater leaks or no hot water
- Low water pressure throughout the home
- Major leaks you can’t locate
