sewer vent frost closure
Posted by GJChristensen on December 02, 1999 at 17:56:03:
We live in Minnesota and our house was built 5 and 1/2 years ago. Everytime it snows we have problems with frost closure in all four sewer vents coming out of the roof of our house. These vents range from 2 and 1/2" to 4" in diameter. Are there any products out there that we can install that will illiminate this problem? Climbing on the icy roof to break the vents over everytime it snows is not a very safe practice. We really need some good advice.
