Roof shields surrounding vent pipes can leak if the sealant is old.
Vent pipes are attached via connecting couplings to various sewer lines in your home. Depending on local building codes, each water fixture can have its own individual vent line (toilet, shower, sink, etc.), or sometimes vent lines can accommodate more than one fixture. Vent pipes can crack in extremely cold conditions, or sometimes break if old. The vent sealer around the roof shield can also crack if old, allowing moisture down into the wall cavity. Either job is fairly simple to address and not very time- consuming. Does this Spark an idea?
Instructions
Fixing Broken Vent Pipe
1. Mark the vent pipe six inches both above and below the break/fracture--use a felt tip pen. Cut through the pipe at both marks with a hacksaw. Make sure the cuts are straight and remove any burrs with a work knife.
2. Measure the distance between the two cuts. Cut a new piece of vent pipe to this length and remove the burrs.
3. Apply ABS glue to the ends of the new pipe. Also apply glue to one inside end of two straight ABS couplings. Push the couplings onto the ends of the pipe.
4. Glue the two cut ends on the existing pipe, as well as the remaining inside ends of the two couplings. Squeeze the couplings/new pipe between the cut ends of the existing cut pipe. Hold in place for 30 seconds.
Resealing the Roof Shield
5. Brush away any dirt from the area where the vent pipe enters through the roof shield.
6. Scrape away any loose roof sealant from the roof shield area-, using a work knife.
7. Squeeze the sealant onto the area where the pipe enters up through the shield. Use a brush to smooth out the sealant so that it fully surrounds the pipe.
