Installed radon system 7 years ago - still going strong
(Ann Arbor, MI)
I installed a radon mitigation system myself 7 years ago with products and information obtained from this website. It's been running non-stop since then without any problems, and it still draws the same amount of vacuum. It dropped my radon levels from 20 pCi/L down to 0.5 pCi/L, where it's stayed ever since. I'm definitely a satisfied customer.
