Plumbing Supply Lines

Several problems can arise within your homeʼs plumbing supply lines. It is important for the homeowner to quickly identify each issue as it arises so the problem be resolved to prevent potential damage to the home.

Leaking, Frozen and Burst Water Supply Lines

If a leak is detected in a water supply line, the water supply to the house or affected area should be turned off immediately and the builder and the insurance provider should be contacted. Water leaks can create safety hazards around electrical outlets and wiring, and can pool in unseen areas causing hidden structural damage or mould.

Preventative Measures

When colder weather approaches, disconnect exterior hoses, shut off exterior valves and allow the water line to the exterior hose to drain. “Frost free” lines will not protect outside water supply lines from freezing if the exterior hoses have not been disconnected from the threaded connection. Clean up water from a leak as soon as possible to minimize damage to flooring, walls, furniture, etc.

Condensation on Toilets and Water Supply Lines

Condensation occurs when pipes or toilet tanks are cooler by the movement of cold water on the inside and the exterior environment is warm or humid. This typically happens on the toilet tank or the toilet water line and is most common right after a shower or a bath and right after the toilet tank has filled with cool water.

Preventative Measures

The best way to prevent condensation on toilets and water lines is to ventilate the area by opening a window or turning on the exhaust fan to remove excess humidity from the room or your home in general.

Tap Water Supply is Inadequate

There are several reasons why the water supply to a toilet or sink may seem insufficient, however in some cases, this issue is unavoidable. Possible causes may include the following:

  • The shut off valves may not be fully open. The shut off valve is usually located on the water line that feeds the sinks or toilet. Check to ensure that the valve is open fully.
  • The water pressure and supply to your neighbourhood your home is regulated by the municipality. Variations may occur in municipal water supply pressure during peak periods of demand or between neighbourhoods.
  • If your home is located in the country and you use a private water system (i.e., wells, cisterns) you may be able to adjust the pressure regulator valve located on the outlet of the pressure tank. This regulator should be set to between 40 and 80 pounds per square inch (PSI) of water pressure.
  • Most water faucets in bathrooms have faucet aerators that may restrict the flow for water conservation. This is not a defect. Clean the faucet screens by unscrewing the aerator from the faucet tap and cleaning away any buildup or debris.
