Role of the pressure vessel
The pressure vessel helps stabilise pressure and reduce how often the booster pump starts. If it fails or loses charge, the system can become noisy, unstable or start and stop too often.
Symptoms of a vessel problem
Common signs include short cycling, rapid pressure changes, water hammer, pump starting with tiny demand, unstable pressure and increased pump wear.
Possible causes
Possible causes include loss of air charge, failed bladder, incorrect pre-charge, undersized vessel, leaking valves or incorrect system settings.
What to send
Send photos of the vessel label, pressure gauge, booster set, controller and a description of how often the pump starts.
