Terasen Gas maintains your home's gas meter, and the gas service line that extends to it from the street.

 

As a customer, it's your responsibility to maintain the gas piping that extends past the meter into your home, and any piping that may run underground to detached buildings, pools or outside appliances like barbecues or patio heaters.

A registered gas contractor, or leak inspector (look under Inspection Services in the Yellow Pages), will locate and conduct specialized tests to ensure the gas piping you can't see — your buried gas piping — is functioning safely and efficiently.

 

 

It's a good idea to have a registered gas contractor inspect visible and buried gas lines at the same time you're having your gas appliances and furnace serviced.
