What must suction pits or piping configurations not compromise?

The focus of suction pits or piping configurations in radon mitigation systems is primarily on maintaining the efficiency of the mitigation system. These systems are designed to effectively reduce radon levels in indoor environments by creating a negative pressure that draws radon gas away from the home and vents it safely outside. If the suction pits or piping configurations compromise the efficiency, it may lead to increased radon levels, potentially putting the occupants at risk.

Maintaining proper configurations is essential to ensure that the radon gas is adequately captured and vented. Any modification that affects the suction abilities could lead to less effective mitigation. Therefore, the correct answer reflects the necessity of keeping the efficiency of the mitigation system intact to protect human health. Other considerations, although important in a broader context, do not directly impact the specific function and effectiveness of the radon mitigation process.
