I can't imaging a furnace being used with the drip leg "off" and laying on the floor.
Someone would have smelled the gas, and it wouldn't have taken "days" for an explosion to happen.
Back in November, the whole house was leveled by a huge explosion. Focus turned immediately to the HVAC contractor since the furnace was replaced days before. The lawsuit photos show the drip leg was disconnected, and laying on the ground. Wonder if that worked itself loose, or was left off completely?
Maybe the "friend" used the drop leg as a stash for his favorite drugs.
An update to this one.. It looks like the victims will be paid by the insurance company.. but I don't think the attorney is done, yet.
In the second article, they discuss the detached drip leg once again:
"The wrench showed loosening marks, not tightening marks," said Rottier. "You can tell which direction the wrench was turned."
