On arrival, found that water was leaking out of the air handler stand in the bottom corner. Introduced water to system and found that the leak was coming from the threaded connection from condensate pan to PVC pipe. Disassembled condensate piping and found that the threaded male adapter was cracked between threads, which would be the cause of the leak. Replaced male adapter and tested condensate drain. Found no other water leaks. System is now in good operating condition.
