Response to My PAC FAB Nautilus filter, 20 years old, is dripping from the outlet of the top of the pressure relief valve. I need a replacement. All I see available are 'Manual Relief Valves' p/n 273550. They do not show a top air relief, only a manual thumb screw bleed port. Every day when the timer turns the pump on, air vents out all by itself, the stops when the filter is charged with water. I can't see how that can happen with the manual valve. What is the p/n and where can I buy the auto relief valve?
