California Law Requires a Main Water Shut-Off Valve
Is Your Home Up to Code? Missing This Required Valve Could Cost You. Avoid Fines, Water Damage & Code Violations
Why You Need a Main Shut-Off Valve — Now
Water damage doesn’t wait. A single burst pipe can cause thousands of dollars in damage within minutes — soaking drywall, flooring, furniture, and even the foundation. The only thing standing between a leak and a disaster? Your main water shut-off valve.
Without One, You’re at Risk for:
Major water damage during plumbing failures or pipe bursts
Slab leaks and unseen water waste costing you hundreds on your water bill
Failed inspections during remodels, sales, or insurance claims
Code violations under the California Plumbing Code (CPC §606.2)
“Each building supplied by a separate water service shall have a separate shutoff valve near the point of entrance.”
— California Plumbing Code, Section 606.2

Who Needs One Installed or Inspected?
If you’re a homeowner in California—especially in Murrieta, Temecula, or the surrounding areas—you are legally required to have a working main water shut-off valve. Whether your home was built before modern plumbing codes or you’ve never had the valve professionally inspected, it’s crucial to confirm your system is up to code. Many older homes are missing this essential feature, and some newer homes may have faulty or hard-to-reach main water shut-off valves that won’t protect you in an emergency. If you’re unsure whether your shut-off valve is compliant, it’s time to act—especially before you’re hit with water damage, fines, or denied insurance claims.
You should contact us immediately if:
You don’t know where your shut-off valve is
Your valve is rusted, stuck, or hard to access
You’re planning a remodel, ADU, or home sale
You want better leak protection or monitoring
You just want to be safe, prepared, and up to code
Don’t wait for a burst pipe or a surprise home inspection to reveal the problem. Prestige Plumbing offers fast, affordable installation and inspection services—and we recommend upgrading to a Moen Flo Smart Water Monitor & Shutoff for added protection, automation, and peace of mind. Contact us today to schedule your main water shut-off valve inspection or installation, and stay compliant, protected, and prepared.

Main Water Shut-Off Valve FAQs
Do I really need a main water shut-off valve?
Yes. In California, it’s required by the California Plumbing Code (CPC §606.2). Every building that’s supplied by a separate water service must have a clearly accessible shut-off valve near the point where the water line enters the building. It’s not just about code — it’s about safety and protecting your property.
What happens if I don’t have a shut-off valve?
Without a shut-off valve, you risk:
-
Major water damage in case of a leak or burst pipe
-
Longer emergency response times (while searching for a water main)
-
Failed inspections for home sales or remodels
-
Fines or code violation notices in some cases
How do I know if my shut-off valve works?
If it’s rusted, stuck, inaccessible, or hasn’t been turned in years — it may not function in an emergency. If you’re unsure, Prestige Plumbing can inspect it and recommend whether to replace, repair, or upgrade your valve.
What’s the benefit of a smart shut-off valve?
The Moen Flo Smart Water Shut-Off Valve:
-
Detects leaks automatically, even small ones
-
Lets you shut off water remotely via smartphone
-
Monitors water pressure and flow 24/7
-
Helps prevent catastrophic damage
-
Can qualify for insurance discounts
It’s one of the smartest upgrades you can make to your plumbing system.
Can you install a shut-off valve in any home?
Yes — whether you’re in an older home with no visible valve or just want a smart upgrade, we can help. We install standard shut-off valves and smart valves like the Moen Flo for homes in Murrieta, Temecula, Menifee, and surrounding areas.
How much does it cost to install a shut-off valve?
Costs vary depending on the location of your water main, the type of valve, and whether you’re opting for a standard or smart shut-off system. Call us at (951) 330-7139 for a quick estimate or to schedule an in-home inspection.
Will installing a shut-off valve disrupt my water service?
Only briefly. In most cases, we can complete the installation or upgrade in a few hours. Our licensed plumbers will minimize downtime and ensure your system is tested and fully operational before we leave.
Can I include this with my other plumbing work?
Absolutely. Many customers bundle this with repiping, water heater installations, or leak detection services. If you’re already upgrading your plumbing, it’s the perfect time to make sure your home is protected with a compliant shut-off system.
