Questions on assembling b-vent pipe
I've noticed that the b-vent pipes are designed to snap together tightly. Do you still need to fasten them together with sheet metal screws?
Also are b-vent products from different manufacturers compatible? The local HD has American Metal Products, but they do not have some of the lengths I need and I may have to go looking at other stores. If, say the local lumberyard has b-vent piping from a different vendor, could I still use it with American Metal Products pipe?
