Why Your Main Shutoff Valve Matters
Your main shutoff valve is the one valve that turns off water to the whole house. In most homes across Pasadena and the San Gabriel Valley, it sits where the water line comes up out of the ground, usually on the front or side of the house near a hose bib. When a pipe bursts or a water heater starts leaking, it’s the first thing you need, and every minute it stays open means more water on your floors.
Many older homes still have the original gate valve, the kind with a round handle. After years of hard water and sitting untouched, gate valves seize, the handle snaps off, or the valve turns but never fully stops the water. Some start leaking at the stem the moment you touch them. Most people find out during an emergency, when it’s too late.
We replace old gate valves with a new quarter-turn ball valve that shuts off fast with one easy turn. We check your main valve on every visit, and if it’s stuck or leaking, we’ll show you and give you a flat-rate price to replace it. Same-day service available.
More Ways We Can Help
Ready to stop flushing a tank and get endless hot water? We install Navien, Rinnai, and Noritz tankless units sized to your home, and many homeowners qualify for SoCal Gas rebates on the switch.
Hard water is what seizes old valves and builds scale inside your water heater. A water softener protects your pipes, valves, fixtures, and appliances. Most systems can be installed the same day.
No hot water, a pilot that won't stay lit, or a tank that's already leaking? We repair and replace gas and electric tank water heaters, with same-day replacement on most standard sizes.
Shutoff Valves We Install
We install lead-free, full-port brass ball valves from Apollo, Watts, and NIBCO, sized to match your main line. A full-port valve opens as wide as the pipe itself, so you don’t lose any water pressure. We add a union where it makes sense, so future work on your main line is faster and easier.
Want the water to shut off by itself when a leak starts? See our smart water shutoff page.
What To Expect
We start by finding your main shutoff and testing it. If it’s stuck, leaking, or won’t fully stop the water, we shut off the water at the meter, cut out the old valve, and install a new full-port ball valve. Most replacements take one to two hours.
Then we turn the water back on slowly, check every joint for leaks, and run the air out of your lines. We also test your water pressure and check the pressure regulator next to the valve. Before we leave, we show you how to use your new valve and give you a quick rundown of everything we found.

Frequently Asked Questions
-
In most Southern California homes, it’s outside where the water line comes up from the ground, usually on the front or side of the house near a hose bib. It’s often right next to the pressure regulator. If you can’t find yours, we’ll show you where it is.
-
If the handle won’t turn, the valve leaks at the stem, or water keeps running after you close it, it’s time. Old gate valves with round handles are the ones that fail most often.
-
A gate valve has a round handle you turn many times, and it can seize or break over time. A ball valve has a lever that shuts off the water with a quarter turn. Ball valves are faster, more reliable, and easier to use in an emergency.
-
Most replacements take one to two hours. Your water is off during the work, and we turn it back on and check for leaks before we leave.
-
The valve at the meter belongs to your water company. The valve at your house and the pipe from the meter to your house are yours. We work on your side, and if the meter valve needs work, we’ll tell you who to call.
-
Call your water company’s emergency line. They can turn the water off at the meter. Then call us, and we’ll come out the same day to fix the leak and replace your main valve so it works next time.
-
If you travel, have an upstairs bathroom or laundry, or want a home insurance discount, it’s worth it. A smart shutoff closes your main automatically when it senses a leak. We can install one during the same visit.
