I have a heat pump in my garage that is located against an interior wall to my downstairs den. It has overflowed into the garage floor and water has. One under the wall to the carpet in the den and downstairs hall ( which leads to door to garage). I replaced the pump and the tubing but it still leaks a bit. Long story shorter is I’m having someone look st system and will have to have the carpet replaced, Again. My question is this... Before I invest in flooring again, does anyone know a way to waterproof this area of the wall in garage behind the unit; namely where the cement floor meets the drywall? Hate to keep replacing flooring only to have all of this happen again! Thanks in advance!

You can caulk the gap but if the floor slopes that way, there's little that can overcome a significant amount of water short of grinding some of the concrete away to create the proper slope.

 

Hi, Heat pump in garage? What pump did you replace ?

I think he's air handler is in the garage, which would make sense. In that case, an overflow pan should be placed under it with a switch to shut down the condenser if the drain over flows.
