Condensate pipe touching basement floor ok?
Yes, the floor was the downfall of the old pipe, the copper will do much better. While everything looks dry, the floor &amp; bottom of the wall concrete is moist from microscopic condensation, since they're always colder than the air.

Starting the condensate pipe as high as possible will minimize pipe problems &amp; more importantly draining problems. You want the pipe pitched downward for as far as possible to the sump.

Preferably the pipe should never be flat or level &amp; it should have a close by trap, like under your sink. The pipe should also have a clean-out, this is actually a bleach pour-in. Condensate is quite nasty &amp; stinks if the pipe's not bleached once a year or as needed.
