apparently gas leakage can occur for up to an hour.
So here's what happened:
I smell gas while changing filter.
Call technician to come check.
Finds small leak in pipe connection - problem fixed.
Wife still smells gas, calls utility co.
they find leakage at first burner orifice - get red tagged.
Call technician again - order new valve.
New valve installed - problem fixed.
Wife still smells gas.
I check with cheapy detector - leakage at first burner orifice
Call technician - ordering new replacement for bad new valve
I have a feeling we'll have the same outcome.
So is it safe?
How do I convince my wife that it is?
