I just got a new High Efficiency water heater to replace an old 15-year old not high efficiency. The new unit has a whole bunch of condensation tubes and pipes coming out of it and it ties into the drain in the floor (which previously only tied into the drain pan).
And the drain on the floor goes down three stories (I live in a condo) and out the outside of the building, where it has froze up.
I don't have any other drains in my utility closet where the unit resides.
What kinds of options do I have other than getting angry at the installer for not checking where the drain terminates and warning me about using a unit with condensation?
I'm very concerned I will have to ditch this $3000 unit and get a whole new, non-efficient one like the one I had before which was crap because we can't accommodate a continual drainage.
Is it possible it froze because it was dripping on the gas line pipes and created a stalactite back up into the drain terminal? The amount of pipe coming out of the side of the brick outside is about 1 foot long of 2" PVC.
The biggest concern is that it will continue to back up to the second story and back-flow through the drain pipe in the unit below me.
