So I have the Frabill bait station 19qt and its awesome.I like that it uses battery,cigarette lighter plug or 120v.The issue is with the lid closed and latched it eventally builds up pressure and forces water out of mounting for aerator on lid which isnt fun when its on front rack of quad.Has anyone gone thru this and figured out a way for it to be still be water tight but bleed off excess pressure? I know i could just drill a hole in lid but still want it to be water tight. Any suggestions?
Short answer: no. Anything you do to relieve air pressure will also allow water to come out as well so your watertight will be gone.
Other solutions: If it's just a short hop turn off the aerator until you reach your destination. If you have a two speed aerator switch it to low. Or pause occasionally and just release the latch to relieve the pressure.
I initially thought of a mini check valve but that would allow water as well as the air to escape and would probably freeze in very cold weather. Perhaps just a tiny hole and a length of vinyl tubing (like 1/16th inch) to direct any water to a better place?
Maybe it's even easier. What is the "aerator mounting" that allows air/water to vent? That could be the simplest answer. Pics?
