Need some advice from someone familiar with a comfortmaker heat pump
My Daughter's Comfortmaker Heat Pump (approx. 12 years old) has a PVC
condensate drain at the evaporator coil but, in addition, has two
short 1/2" copper tubes protruding from the cabinet, one offset and
slightly above the other and both somewhat above the PVC Drain pipe.
They each protrude outside of the cabinet approx. 1" and are open to
the outside (disconnected). My daughter said there used to be a blue
plastic hose connecting the two but it has since deteriorated.
Now, the condensate drains from the uppermost copper tube, instead of
being directed to the PVC Drain.
Does anyone know what these two short copper tubes are for and if and
how they should be connected - if at all ?
Meanwhile, I'm going today - to see if the PVC Drain is clogged.
Thanks for your help
