haven't found anything specific to my issue, so I figured I'd give it a shot here.
I have an outdoor, tankless water heater. It is mounted in a recessed wall on the back of our house. It has a a short, horizontal vent "mouth."
Last night when my wife was in the shower and she turned off the water, I happened to be standing by the back window and noticed a fairly decent amount of water "belch" out of the vent. I am also able to replicate the experience on a smaller scale, using the bathroom faucets; i.e. upon turning off the hot water, after about a 5 second delay, about a tablespoon of water will come out of the vent. Any ideas?
