What to Do Right Now (10-Minute Checklist)
- Shut off the main water.
Most Valley homes have the main by the street in a ground box or on the side yard near the hose bib. Turn the valve clockwise until it stops. If you’re not sure, call our Emergency Plumber Los Angeles team and we’ll guide you. - Turn off the water heater.
Gas: set to “Vacation.” Electric: switch off the breaker. This protects the heater when the water is off. If your heater is acting up, see Water Heater Repair. - Move electronics and rugs.
Clear a path for the plumber. Put towels at doorways to slow water. Consider upgrading old shut-off valves during your next Fixture Installation visit. - Open a low faucet.
This drains pressure from the lines so leaks slow down. - Protect floors.
Use a dustpan or squeegee to push water toward a floor drain or outside. - Take quick photos or a 10-second video.
This helps you remember details and can help with insurance. - Check for a gas smell.
If you smell gas, leave the home right away and call your gas utility emergency line. Once safe, we handle Gas Line Installation & Repair (permits, pressure tests). Learn more in our safety guide: Gas Line Repair Safety. - Find the clean-out.
If sewage is backing up, locating the clean-out cap (often near the front or side of the house) saves time. See how we clear heavy clogs with Hydrojetting and compare methods in Hydrojetting vs. Snaking. - Secure pets.
We love pets, but they can get scared. Keep them safe in a room. - Call a licensed pro.

FAQs
1) How fast can you get to a home near CSUN in Northridge during morning traffic?
2) Where is the main water shut-off in older Valley homes (Reseda, Van Nuys)?
Most are in a ground box by the curb or on the side yard near the hose bib. Townhomes sometimes have shared shut-offs—if you can’t find it, schedule Leak Detection & Repair.
3) Do you service apartments and small businesses along Ventura Blvd in Sherman Oaks and Encino?
Yes. We handle after-hours access, COI, and parking. For heavy grease lines, ask about Hydrojetting and see Restaurant Drain Survival in LA.
4) My yard near Lake Balboa stays soggy—could it be a hidden leak?
Yes. Constant moisture by the sidewalk or meter often means a service line leak. We pinpoint with acoustic/thermal tools and provide Drain Line & Water Line Repiping if needed.
5) Can you reach North Hollywood or Panorama City late in the evening?
We offer same-day and emergency service. Check our Los Angeles Service Area, nearby cities like Burbank and Glendale, then Book Online.
