Found basement system, condensate removal pump unable to pump water. Replaced condensate removal pump with new pump. Flushed all drain lines to ensure water flow. Also vacuumed water from emergency pan. Also tied in the new pump safety float switch so that if pump were not able to remove water, it would shut down system before water overflows.
