Review on Lippert Components 389381 Siphon Roof by Michael Welborn

I had a 1 and 1/4" ABS breather tube and the adapter from the kit fit the tube perfectly as shown/described in the instructions. No need to overcomplicate it like reviewer Stephanie did with two extended tubes. If you need to relocate them, just add the coupler and tube one by one and make one taller. The kit includes the parts you need to fit a 1.25" tube etc. There are even pictures showing how to install it into a duct. She didn't follow the instructions and cut off the strips! Carefully cut off the plastic tabs. The instructions show how to install the system on the four main types of vents with diagrams and it went very smoothly.Also it seems to work as advertised,I don't feel anything after installing it.We love it but it must cost 10 bucks and then gets it everyone.
