What are the operating characteristics of a "waterlogged" potable water system hydro pneumatic header tank that needs to be recharged with compressed air?

Correct Answer: Option C — Very short and frequent running and idle periods for the potable water pump.

A waterlogged hydro-pneumatic tank lacks the necessary air cushion to absorb pressure fluctuations. Consequently, the pump starts immediately upon any demand and stops instantly when demand ceases. This rapid cycling leads to excessive wear on pump motors and starters, necessitating immediate recharging of the air cushion to restore system elasticity.
