How often must the pressure head of a pressurized system be checked for compliance?

• A. Every 12 months
• B. Every 24 months
• C. Every 36 months
• D. Every 48 months

Answer: (C)

Regular checks of the pressure head are needed to ensure the pressurized system continues delivering effluent at the intended pressure and dosing volume. The pressure head governs how the pump distributes water through the laterals, and over time components such as seals, gauges, and switches can drift or wear. Verifying the system on a 36-month cycle keeps reliability high while avoiding unnecessary costs from more frequent inspections. If checks are done less often, small issues may go unnoticed and lead to improper dosing, poor distribution, or system failures. Conversely, more frequent checks tend to be unnecessary for most systems and add avoidable expense.
