Air line drain close to floor

[Sugarkryptonite]

Hi guys

I'm running a pex line (don't need any opinions on pex pls) to run air to my barn about 30ft from my shop. My shop is the low point. To be able to have a slope, I had to make the pex enter the shop almost near the floor.

I sloped it for any water to drain out as the underground run is a "low spot" in the system.

Any ideas on what I should use for a drain at this low point? Since it's so close to the floor (~1.5"), not sure what to use. The pex line will go vertical up the wall to the rest of my air lines (not finished yet in the picture).

I wouldn't worry too much about the slope , but.... I would put a tee ( the branch of the tee) onto the pex with a valve pointing down ( even on an angle) and your feed off the top of the run of the tee

What Cobbler said. As close to the floor as you are, the drain side of tee will have to almost parallel to floor. Slightly turned down.

Thanks guys. After brainstorming overnight and your suggestions this is what I came up with.

that'll work fine too.
