How to Replace a Main Water Shut-Off Valve Edmonton
Why Replace Your Main Water Shut-Off Valve?
The Critical Role of Your Main Shut-Off Valve
Your main water shut-off valve is the first line of defense against catastrophic water damage in your home. This crucial component allows you to quickly stop all water flow in case of:
- Burst or leaking pipes
- Fixture failures or overflows
- Planned plumbing repairs or renovations
- Extended absences from your home
Signs Your Valve Needs Replacement
Leaking or dripping around the valve stem or body
Difficulty turning the handle due to mineral buildup or corrosion
Incomplete shutoff – water continues to flow when valve is closed
Visible corrosion or rust on the valve body
Age – valves over 20 years old are prone to failure
The EPCOR Coordination Process
Important EPCOR Information
Before replacing your main water shut-off valve, you’ll need to coordinate with EPCOR to have your water temporarily shut off at the property line. Capital Plumbing will guide you through this process, but here’s what you need to know:
EPCOR Toll-Free Phone Number:
Initial EPCOR Contact
Call EPCOR at 1-800-667-2345 and inform them you need your main water shut-off valve replaced. Tell them you’re working with Capital Plumbing for the replacement service.
Request a CC Test
We strongly recommend requesting a CC test before scheduling the water shutoff. This critical test checks the condition of the curb stop valve (also called the CC valve) at your property line.
Why this matters:
- The CC test ensures the curb stop valve is operational before scheduling the work. If issues are found, they can be addressed first, preventing delays on the day of your scheduled replacement.
EPCOR Site Visit
EPCOR will send a technician to inspect your CC valve, usually within 3 business days. They’ll check if it’s accessible and in good condition. You’ll receive a call from EPCOR about the outcome.
If the CC valve is operational:
EPCOR will call you within three business days to schedule a date to turn off the water. They’ll also inform you of any applicable fees.
If the CC valve is NOT operational:
EPCOR will call to discuss whether the valve must be repaired or replaced before proceeding with your main shut-off valve replacement.
Coordinate with Capital Plumbing
Once your EPCOR appointment is confirmed, contact Capital Plumbing at 780-451-5666 to schedule our technicians to arrive at your home shortly after EPCOR turns off your water. We’ll ensure a smooth, efficient valve replacement.
Main Water Shut-Off Valve Types
Ball Valves
Our Recommended Option
Quarter-turn operation for quick shutoff
Reliable, long-lasting performance
Less prone to leaking or sticking
Clear visual indication of open/closed status
Ball valves are considered the most reliable option for main water shut-offs and are our recommended choice for replacements.
Gate Valves
Common in Older Homes
Multi-turn wheel mechanism
Allows for flow regulation
More prone to mineral buildup and sticking
Often develop leaks as they age
While common in older installations, we typically recommend upgrading gate valves to ball valves during replacement for improved reliability and ease of operation.
