I have a bi-level ranch, just moved in, first house so excuse any mis-terming of items.
In the 2-car garage, the main sewage drain pipe that is angled into the ground always drips (slowly about every
15 seconds) whenever it rains, no other times at all. The pipe seems to have 2 others connecting to it, from the right & left. I can't cut the sheetrock to get a better view of the vertical dripping because there is a horizontal wood beam blocking my view of the drainage pipe if I were to stick my head up into the ceiling sheetrock.
I checked the attic while it rained hard and there are no obvious leaks and all the roof openings are bone dry with cobwebs around some of them. My house also has 2 overhangs, both sloping away from the house along w/ the gutters which are leak-free.
The only culprit I can think of is that for some reason, the vent pipe sticking out of my roof (not from the furnace, that one is covered), collects water whenever it rains and that water finds it's way out of a perhaps broken seal or something somewhere and it hugs the pipe down into the garage. Because the roof water vent pipe seems to be directly above the problem area in the garage...I was going to try 2 things to fix this even though I'm not sure where the drip starts from:
- Cover the vent pipe (not sealed, just to prevent rain water getting in, but air will still get in/out)
- Water sections of my roof/gutters with a hose to try and re-create the leak and figure out where it is coming from....
Any other ideas? Unless of course it is somehow coming from where my raised deck is bolted to the side of the house, but I find that to be a stretch of the imagination....
Thanks!!!
