Turns out there's a one-way vent cap in the drain pipe designed to help the system drain faster (at least there is in ours). Also turns out that you can easily replace this vent. Who knew! Well, I didn't. Bought new vent caps on Amazon, unscrewed the old, and screwed on the new...with a little thread tape to seal it.

Anyway, it's that simple. Thought I'd share.

Jeff ain't that the truth! Sort of sheepish to admit, but I spend a lot of time on the forum just learning from others - just like in this case. Sure has been a great place to land and find new folks to bounce ideas off of too! Glad you nailed down your issue and it was a simple fix.
