Mike Lamb Posted May 24, 2013 Report Share Posted May 24, 2013 The air conditioning condensate drain empties into this plugged floor drain which has a hole drilled in it. If this floor drain has water in the trap is there anything wrong with this? Would it need to be primed trap? I'm not sure what these wires are all about coming out of the drain. They used to plug into something, perhaps an alarm to warn of drain backup? Click to Enlarge 39.65 KB Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted May 24, 2013 Report Share Posted May 24, 2013 If there is a trap that maintains a seal through the winter, there still needs to be an air gap for a proper indirect waste receptor. Quote Link to comment Share on other sites More sharing options...
Marc Posted May 24, 2013 Report Share Posted May 24, 2013 What Bill said but do confirm a trap in the condensate line near the air handler/evaporator coil also. It keeps air pressure in the evaporator cabinet from pushing/pulling on the seal in the plumbing trap. It also keeps conditioned air from escaping via the condensate line.
