The Stuber’s had us out because of water in water heater pan. Water level is not quite yet to the drain pipe but close. I would give it a matter of days till water level in pan suffocates burner. Pan plumbing does appear to be appropriate enough to avoid pan from over flowing. The Stuber’s would like a little time to discuss wether they would like to do a power vent replacement, or convert to a tankless. I will be following up with the Stuber’s tomorrow to discuss the proper solution. The Stuber’s currently have hot water.
