Did a search but wanted to ask as well. When you guys use the leaf blower to clean vent pipe do you also use a cleaning brush? And if so do you use the cleaning brush first and then the leaf blower. Or leaf blower then cleaning brush then leaf blower again? Another question is do you need to take apart the cleanout on the T before using leaf blower or will the leaf blower suck out everything in the T? So you dont need to remove cleanout on T?
