Water in clean out tee

[Nvnv]

I was gone for the last week on vacation. Came home and before starting up the pellet stove I went and pulled the cap off my clean out tee to make sure everything was clear. The cap was almost full with water. I have my vent going out the wall from the stove then the tee is outside the house and then up three feet to the weather cap.

Could the water just be from condensation and from not using it? All my connections are sealed with silicone and I don't see how water could get up through the weather cap. Is it possible to drill a tiny drain hole so this doesn't happen again?

You probably have a leaking pipe seam, If you have an elbow at the top of your pipe it's probably one of those seams that allow the elbow to twist.

That's basically how my stoves are plumbed, and when I had that issue a few weeks ago, it was because of high winds and heavy rain. My spruce trees cause a wind turbulence behind them that was sending rain near horizontal at the side of the house and into the chimney outlet. Rain cap did'nt know how to deal with horizontal rain.

I'm thinking this might be it. I went at it with the foil tape today on the seams of the top elbow and the weather cap. I'll keep an eye on it and see if that helps.
