I am getting my electric releaser setup and trying to figure out if I need to put in a moisture trap. For one the releaser itself has a ball in a cage on the vacuum port that looks like it would prevent water from getting sucked into the vacuum line. Also, the vacuum pumps are 400' away with a difference in elevation of ~20'. It seems like between those two things it would be pretty hard to get any moisture up to the pumps.

What do the veterans say?
