Licensed and Experienced Local Plumbers
In every home, the water distribution system relies on a series of shut off valves. The most important one is the main shut off valve, typically located near the water meter in the basement. It controls the water supply for the entire home. Other essential shut off valves are installed at specific fixtures and appliances — including under sinks, behind toilets, on the water heater inlet, for washing machines, and for outdoor garden taps.
These valves are not just practical — they are mandatory under Ontario plumbing codes. For example, if a toilet mechanism fails and causes a leak, the dedicated shut off valve allows you to isolate the issue without shutting off water to the entire house.
Over time, however, shut off valves can deteriorate due to age, corrosion, or poor installation. Common issues include:
- Stuck or broken handles
- Incomplete shut-off
- Dripping from the valve stem
- Leaks at the joints
- Rust or heavy corrosion
- Restricted water flow due to clogging
- Excessive force required to operate
If you live in Mississauga and are experiencing any of these issues, our team of licensed plumbers at Mister Plumber and Sewer Expert is ready to help with professional shut off valve repair, replacement, or installation.
Replacing Your Main Shut Off Valve in Mississauga
In most cases, replacing a shut off valve requires turning off the water supply and draining the line. If you’re planning to replace the main water shut off valve, there are a few important steps involved:
- Book a licensed plumber.
Contact Mister Plumber and Sewer Expert in advance and share photos of your current setup. This allows us to bring the right tools, fittings, and valve sizes. - Arrange for curb stop shut off.
Before the main valve can be replaced, you must call 311 to have the City of Mississauga temporarily shut off the municipal water supply at the property line (curb stop). In rare cases, the city valve may be damaged or inaccessible — if so, the City will need to repair it first. - Professional installation.
Once the curb stop is off, our plumber will replace the old valve using top-quality parts and modern tools to ensure a leak-free, code-compliant installation.
Other shut off valves inside the home (under sinks, behind toilets, etc.) can typically be upgraded without calling the city, as long as the main valve is functional.
Do You Need to Provide a Valve?
No, you don’t. Our plumbers come fully equipped with all necessary parts, including different valve types and sizes for copper, PEX, or PVC pipes. We’ll select the most suitable shut off valve for your system — saving you time and ensuring the installation is done correctly the first time.
