Did you see my last blog. I just addressed something like this happening.
We were called to check on a system installed by another company because it was not lowering the Radon levels sufficiently. The installing company would not come back unless they were paid up front. Nice. (This goes hand in hand with my last blog) We made an appointment to come back to the home to basically fix everything on it. Look at the quality of work that is being done out there. Using hole saw biscuits to prop up a pipe for pitch? I’m sorry for the strong language here, but this
is just crap. How can you install something like this and take someones money. My brain does not function that way. My installers would never do this because they are trained properly, and would be fired if they did. If you run out of studs to use, you make a trip to the store and get some more. Also, the piping. Clearly not schedule 40. The 90 degree turn is way too sharp and greatly reduces air flow. Not to mention the flimsy pipe will produce a lot more noise. We will post more pics after the system is fixed.
