Should pea gravel be used in a low-pressure pipe dosing system?

In a low-pressure pipe dosing system, using pea gravel is not recommended because it can impede the flow and distribution of effluent. Pea gravel is small and rounded, which can create voids between the stones, leading to uneven distribution of water or clogging issues. The design of low-pressure systems typically requires materials that promote uniform and consistent flow while preventing blockages, such as coarse sand or gravel that has angular shapes which interlock better than rounded materials. Therefore, ensuring proper filtration and effluent distribution is critical to the function and longevity of the system, making pea gravel an unsuitable choice.
