​Main shutoff valve vs. city shutoff valve

Sometimes, you may have to turn off the water coming into your house. For plumbing installations or repairs, or in the case of a flood or back-up, you'll want the water off. Two valves can do this: the main shutoff valve and the city shutoff valve. Most of the time, you'll just need to use the main shutoff valve.

Main shutoff valve

This is attached to the water line that goes into the water meter inside of your home. The main shutoff valve is usually in your basement. Turning off that valve will stop water from entering your home.

City shutoff valve

Also called a curb stop valve or a CC valve, it is found at the property line​​ on your driveway or front yard​. It connects to the underground water main near the street and can be turned off by the utility company. If you need to repair or replace the main water shutoff valve, you'll need the curb stop valve turned off first. Learn more about shutting off your curb stop valve​.

How to find your water shutoff valve

The main water shutoff valve is located next to your water meter. Your water meter will be near the front or back of the house, and usually in a utility room in your basement. Check in crawl spaces near exterior walls or in your furnace room near your water heater.

There will be two valves near the meter. The water shutoff valve is the one located before the meter. It is attached to the pipe coming from the outside wall. You'll see a gate valve or ball valve to open or close the waterline.

Who is responsible for main water shutoff valve?

Homeowners are responsible for the main water shutoff valve. You're responsible for fixing any plumbing issues with pipes, fixtures, and water lines within your home​ and property. That includes the pipe going from your home to the curb stop valve to the city water line. If the shutoff valve leaks, needs repairs or needs to be replaced, it's your job to get it fixed.

The water utility owns the water meter

The water meter itself is our responsibility. If it needs fixing or replacing, the water utility will take care of it. We are also responsible for the curb stop valve, also called the city shutoff valve and the water lines that lead to your property line.

Our crews will repair faulty main lines outside of your property line that may be the cause of flooding or damage. If you're losing water pressure and think the main line is the culprit, we can check for a few things. Soil slumping on the line, tree roots growing through it, leaks, or nearby construction activities can cause issues with your water line or water quality. Contact EPCOR, we're happy to troubleshoot the problem and send our maintenance team if needed. 

How to fix or replace the main water shutoff valve

Over time, mineral deposits and grit can clog the shutoff valve and cause leaks. It can also make it difficult to turn the valve on and off. It is your responsibility to fix it, and we suggest hiring a professional plumber. It requires skill, expertise, and specific tools to do it correctly. Because it's an essential part of your home's plumbing system, you want to make sure to do it right.

Before they get to work, call EPCOR to turn the water off at the curb stop valve. After the repair, contact us again, and we'll turn it back on for you.

Shutting off your curb stop valve (CC)

If you need a temporary water shut off at the property line for home repairs or other reasons, some important tips below will help you understand our process. This will help you plan for the turn off timeframes that may occur:

1. Contact EPCOR dispatch at (780) 412-4500

Common reasons for water turn off requests:

  • ​The main water shut off valve in your home is leaking
    • Very common for valves that have been recently operated to leak through the packing
    • Some valves have a​ packing nut that can be tightened down
    • Use caution if tightening a packing nut, not much force is needed to stop a leak. Small turns, till the leak stops
  • Valve doesn't control the water (seized, handle is broken or missing, gasket inside is worn out)
  • Moving the water line to a new location
  • Precautionary (repairing/replacing sewer lines)​​

2. We will arrange for a site visit to operate the CC valve

  • A technician will come to your address and assess the condition of your CC valve.
  • This pre check can take up to three business days and you will receive a call back from our team to confirm the outcome of the pre check visit.
  • This visit will ensure you are not scheduling a plumber in advance of confirming we can turn the water off.

3.

A) If the CC valve is OPERATIONAL

  • We will call you within three business days to confirm appointment options to schedule a date that works for you.
  • During this call we will review the costs to come to site and turn off the water and the costs to turn on the water for you when the repair is complete. The fees align to the rates outlined in our EPCOR Water Services and Wastewater Treatment Bylaw. 

B) If the CC valve is NOT OPERATIONAL

  • We will call you within three business days to let you know next steps.
  • Following safety and legislative requirements, any repair of a CC valve needing excavation requires EPCOR to call Utility Safety Partners to obtain locates before the work can begin. This will ensure there are no safety concerns with any other utility on the property.

CC valve repair process
  • Employees are allowed to hand expose a CC valve without mechanical means up to a depth of 12".
  • Seasonal factors can cause delays, hand exposing a CC valve is not always successful in colder temperatures as the frost line shifts further in the ground.
  • Any CC valve deeper than 12" or more will require EPCOR to call Utility Safety Partners to obtain locates before any work can be done on a CC that is buried.
  • Any CC valve that paved over or requires mechanical means (jackhammer) to expose the CC, requires EPCOR to call Utility Safety Partners to obtain locates before any work can be done on the CC that is buried.
  • When EPCOR initiates a repair to the CC, the entire process is to ensure the site is safe and ready to repair, this can take up to four weeks to complete.

​In the event of a water emergency, EPCOR will call Utility Safety Partners for an Emergency locate in order to excavate the area to shut off the water.
