Main Water Shut-Off Valve Replacement

If your house started flooding right now, could you stop the water?

Your main shut-off valve is the most important piece of plumbing in your home, but it’s usually tucked away in a dark corner of the basement and forgotten. Most homeowners only realize there’s a problem when they’re trying to do a simple repair—or worse, during an emergency—and find out the valve is seized solid or won't stop the drip.

At Hydra Plumbing, we specialize in replacing those old, unreliable "gate valves" with modern, heavy-duty ball valves that actually work when you need them to.

 If your Ottawa home was built more than 20 years ago, you likely have a gate valve (the kind with the round, faucet-style handle). These are notorious for:

• Seizing Up: Mineral buildup makes them impossible to turn by hand.
• Snap-Offs: The internal "gate" can snap off inside the pipe, leaving your water stuck "on" or "off" permanently.
• Slow Leaks: They often start dripping from the stem as soon as you try to use them after years of sitting still.

We replace these with high-quality brass ball valves. A 90-degree turn of the handle and your water is 100% off. No guessing, no muscle required.

 Replacing a main valve isn't like fixing a faucet. Since the valve is the entry point for your home, the water has to be shut off at the street (the "curb stop").

Don't worry about the logistics—we coordinate with the City of Ottawa to have your water service temporarily paused while we perform the swap. We’ll make sure the timing is tight so your water is back on as quickly as possible.
