Clearing Weep Hole Tubes
We purchased a new construction home with brick facade and what is to my understanding an air gap between the brick and the siding of the house. My understanding is that these plastic weep hole tubes are placed to let moisture drain out instead of getting trapped and leading to mold and other issues.
The problem is that they are mostly full of masonry material. This was noticed during inspection, but it looks like the builder only ended up clearing the few that I happened to check again during walk through.
I tried using a small drill bit to manually scrape out the insides, but it seems like the tubes are a bit longer than I expected and it doesn't seem like I'm reaching to the other side, but I am seeing some moisture at the tip making me worried that there is water already actively building up.
What's the best way to clear these without damaging the system? Someone else posted about replacing these with metal, filtered tubes, but I'm not sure that's needed and I worry about breaking the plastic tubes during removal.
