Volcano Drain

Excellent product / easy to install

After looking at Dranjer valves and not being able to see someone actually use it, I looked for other options that would allow water to drain through the sealed sump pit cover while keeping the suction seal from the Radon mitigation system. It was easy to understand how this drain works and how to install it. It's a simple design with proper function. The video demonstration of its function was also very useful.

Not that good

Works Great

Was concerned it might not work very well but it does.Super easy to install. Would definitely recommend!
