Why does the dampener lose pressure?
The primary reason a dampener will not hold pressure is a failed bladder/bellows. The dampener should be inspected and the bladder/bellows replaced if it has failed. A spray solution of soap and water should be used to check the fittings around the control package at the top of the dampener as vibration over time can loosen these fittings. For a thorough system test, the dampener should be removed from the system. Charge the dampener to working pressure and submerge under water. Any leakage will be seen as air bubbles. CAUTION: Remove all pressure from the dampener AND pumping system before disassembly, removal or maintenance of the dampener.
