Which maintenance interval is described for daily valve inspections?

Answer: A — Daily

Valves affect water flow and pump pressure, and their condition can change day to day due to use, heat, debris, and wear. Inspecting them daily ensures each valve is in the correct position, free of leaks, and that packing, seals, and stems operate smoothly. This immediate, day-by-day check helps catch problems early so the pump and supply system stay ready and safe for service. Because the item specifies daily inspections, that interval is the best fit. Less frequent checks—weekly, biweekly, or monthly—could allow issues like a leaking packing, a SAMPLEstuck valve, or a misaligned handle to go unnoticed, risking pump performance or safety.
