After heavy rain, water pools around our basement furnace. After climbing onto the roof, I found a mysterious (plumbing?) vent.
This post seemed relevant, but 0.5 gallons comes in after a good rain. It seems more than just a flashing issue.
There are 2 such vents on the roof, in addition to the original chimney.
- Would putting some sort of cap on top of the vent fix this?
- What would such a cap be called?
