Common water problems

Here are some common water supply problems that you may experience, and ways of solving them:

No water

No water at the tap can be caused by a variety of factors including:

  • Old galvanized piping in house
  • Plugged water softeners
  • Broken faucets
  • Plugged aeration screens on faucets
  • Plugged water meter
  • Water service or water main leaks
  • Water turned off by the Water and Waste Department for cancellation or nonpayment of bill
  • Possible frozen service (during winter)

For more information, contact 311, and we may be able to help you determine the cause of no water.

Poor pressure

The City's water pressure can vary slightly from area to area and during peak demand times, but on average the City pressure is 65 pounds per square inch.

Poor water pressure can be caused by a number of internal and external factors including:

  • old galvanized piping in house
  • plugged water softeners
  • faulty taps
  • plugged aeration screen
  • plugged water meter
  • water pipe or water main leaks

Leaking service pipes

Things you should know about water leaks:

  • Not all leaks are the City's responsibility to repair. These water leaks include:
    • a leak in your pipe
    • a leak on a fire sprinkler system
    • a leak on a combined fire and domestic service (fire protection and potable supply)
  • Not all water discharges are leaks. What appears to be a leak may actually be: Service repair clamps photo
  • Our crews determine the cause of a leak before corrective measures begin.
  • Before any water main break repairs or other excavation work can begin, all underground utilities (MTS, Hydro etc.) must, by law, be contacted.
    • Scheduling can sometimes take hours or days to coordinate and complete.
  • When we have been cleared to dig, a leak detection crew is dispatched to pin-point the leak.
    • This process minimizes the size of the excavation and maximizes the efficiency of the excavation crew.
  • When there is a leak on a City pipe, barricades are placed at the location to be excavated.
  • Water under pressure (especially in frozen soil or under concrete roads) follows the path of least resistance. This means a leak on a pipe may not be located where the water appears on the surface.
  • Things you should know about leaks on residential property
