Question

The tank regulator on a one month old grill seemed to be leaking so I swapped out for new regualtor.  Same problem occurs and I get both a singing noise from the tank as gas flows, smell of gas from valve on tank, and very low flame height on the ignition burner.  When other burners are turned on, all flame levels decrease as burners are added.  Have also swapped out tanks through Rhino swap system.
