Professional, Licensed, and Local Plumbing Services by Mister Plumber
If you’re a homeowner in Mississauga, having a fully functional main water shut off valve is critical for protecting your property. This valve is typically located where the main water pipe enters your home through the basement floor or foundation wall. It allows you to control the entire water supply to your house — essential during repairs, renovations, or in the event of a plumbing emergency such as a burst pipe or major leak.
Why Replacing Your Main Shut Off Valve Matters
Many homeowners only discover their main shut off valve isn’t working when they desperately need it. Over time, these valves can wear out, corrode, or become stuck — making them unreliable when you need them most.
Common Signs Your Main Shut Off Valve Needs Replacement:
- Water doesn’t stop completely when valve is turned off
- Handle spins but doesn’t control water flow
- Valve handle is broken or difficult to turn
- Water leaks from the valve stem when turning the handle
- Strange noises or pipe vibration (known as water hammering)
- Valve restricts water pressure or doesn’t fully open
- Valve is smaller than the pipe size
- Valve was installed incorrectly
If you’re noticing any of these issues in your Mississauga home, it’s time to call the experts at Mister Plumber. We offer professional main shut off valve replacement and plumbing consultations, performed by licensed and experienced technicians.
The Replacement Process: What to Expect
Replacing a main shut off valve requires coordination with the city and a licensed plumber. Here’s how it works:
- Call Mister Plumber to schedule an assessment and arrange your service appointment.
- Contact 311 (City of Mississauga) to request a temporary shut-off of your water supply from the outside.
- Confirm your plumbing appointment once water shut-off is arranged.
- After installation, call 311 again to restore water service when instructed by your plumber.
- Our technician will test the new valve and show you how to operate it correctly.
Globe Valve vs. Ball Valve: Which is Better?
Older shut off valves are typically globe valves, which use a rubber washer and require several turns to open or close. These tend to:
- Wear out over time due to chlorine exposure
- Leak or seize up
- Reduce water pressure because of a restricted internal opening
Modern ball valves, by contrast, offer significant advantages:
- Full-port design that matches pipe size — no pressure drop
- Chlorine-resistant internal components
- Easy quarter-turn operation with a lever handle
- More durable and longer-lasting than globe valves
Mister Plumber highly recommends upgrading to a ball valve for superior reliability and performance.
