I've seen references to both floor drains and foundation drains, is there a difference? There's a hole in our concrete basement floor approx. 3" in diameter; when I stick my finger in all is feel is dirt/gravel. Is there a P-trap underneath? Our main drain stack and 4"(?) waste pipe is nearby, but it is above ground all the way to where it exits the house.
I ask because we're having a fly issue (not sure if they're Drain flies) in the kitchen, so I want to ensure all P-traps have water. I've never added water to the basement hole in ~13 years, and this is the first fly issue we've had.
