Unlike gravity systems, which rely on uneven flow and can cause localized saturation and premature failure, pressurized flow dividers ensure equal dosing across the entire drainfield via controlled pressure. This results in better biomat formation, slower soil percolation for optimal treatment, and suitability for sloped or remote sites common in Ontario. While gravity systems are simpler and cheaper upfront, pressurized options like those from Canadian Shield Consultants offer longer-term reliability and reduced repair costs in variable Canadian climates.
