Review on Walker 40002 1 1 Diameter Galvanized by Ron Houston

I have this to bleed my concrete saw fumes when working indoors as I installed an exit window last year and need to redo the drain lines in my basement this year. It worked. Something like. What I did was not of typical use and I would not recommend it, although I chose it as a cheaper alternative to buying an electric saw in addition to my (I think more powerful) petrol saw. Access to a machine shop also played a role in my decision now, as I was able to craft the required counterparts. But much to my disappointment, the hose is definitely leaking. It mostly moves outside but my carbon monoxide alarm still goes on and I had to pause to air the room. I think even in normal use it should be more efficient than it is. In short, I would not rely on this hose to fully vent the exhaust, especially in a poorly ventilated situation as carbon monoxide poisoning becomes a very real and dangerous hazard.
