I am planning on installing two durso's in my overflow just for safety sake. I remember reading about another BRS member with two durso's who connected the two so that they could control both pipes with one air hole. I'd like to do the same thing. Do you think think this will work:
External part of durso's. The T's attach to the bulkheads and the bottom of the T's would lead to sump.
