Hydrophore pump short cycling.

• Pressure switch faulty- check pressure switch
• Pressure switch wrongly set
• Non return valve after pump leaking, hence water under pressure going back to storage tank- that would be indicated by monitoring of the concerned pump if reverse rotation is taking place.
• Check on/off controller from pump main panel-contacts opening/closing
• Check if system is overcharged
• Check if system in undercharged- Since water is incompressible as soon as water is filled up pressure rises but just on little consumption pressure will drop drastically and pump restarts
• Check for any air leaks
• Faulty automatic air volume control
• Not enough water in tank due to clogged pipelines
• Air  leaking from relief valve
• Tank is about to empty
