Where does the condensate go now? To a condensate pump? If you
want to eliminate the condensate pump, the usual procedure is to just
route the condensate from the HVAC over to the sump pit. During dry
periods not unusual for there to be no pump running at all. The
condensate just drains into the ground.




Why not just strap the smaller pipe to the larger pipe and let it drain
into the sump pit. If it where you can see the water drip from the line,
that would be good because condensate drains can often clog up.
