What I am hearing from the Sammamish area is that the are many parts of the city that have frequent and sustained outages. This waterfront house had a 11kw installed (10kw on natural gas). After our pressure test passed with Sammamish inspectors we connected the gas line. These types of inspections can be really helpful find if there are any leaks in the gas line. Not only can a leak from an untested gas line be dangerous but it can also add cost to your monthly natural gas or propane bill.
