Please note that in some states you are not allowed to tap into the sump pit. Some states like Illinois have a 422 code written specific to how a system has to be installed to conform. Also a mitigation system should not be installed to a GFCI outlet. Should be wired to a waterproof shut off switch and enclosed in water tight EMT.
EPA Standard 402-R-93-079 Section 14.2.9 requires the radon discharge to be vented a minimum of 10' above finished grade, and if possible near or above the roof ridge line and a minimum of 11' from any doors or windows to allow for dissipation of the radon gas. This prevents concentrations of the gas to be allowed to pool at ground level.

EPA Standard 402-R-93-078 Section 14.2.8 requires the radon discharge to be vented a minimum of 10' above finished grade, and if possible near or above the roof ridge line and a minimum of 10' from any doors or windows to allow for dissipation of the radon gas. This prevents concentrations of the gas to be allowed to pool at ground level.
Radon mitigation with the sump pit works VERY well at my 12 year old house. WARNING / FYI: the little ball drain doesn't actually work if you test it. In theory, the ball is supposed to float up and let water drain in. In reality, the ball gets overwhelmed by the water and ends up being stuck in the down position, blocking the water. I'm guessing the vacuum made by the radon system helps keep the ball from floating up.
Can you explain why the discharge goes *up* into a downspout? Won't that just cascade concentrated radon down on anyone who happens to walk under the discharge? Why not discharge it just above ground level, where it will spread out, at the feet of passersby?

The electrical switch must be within 6 feet of the fan and visible from the fan

Nice looking system. Like the downspout pipe up the side of the house. Much less noticeable than PVC.
