Hi George,

There are four places where air could escape from the accumulator tank:

1. A hole in the rubber bladder.
2. The front stainless steel round plate that holds the bladder.
3. The inflation adapter at the back of the tank.
4. A hole in the stainless steel tank.

You can utilize a foamy solution to try to find the leak. If you see air escaping from the round front plate, you can try tightening the bolts. As the rubber squashes and dries with time and can allow air to escape. The air intake valve in the back (tire inflation type) can also be tightened or a sealant added to the threads. A hole in the tank may be able to be fixed with an epoxy glue, such as JB weld or similar. The solution to #1 is replacement. We found the bladders in Greece a few years ago, I believe in Mytilene marina chandlery, Lesvos Greece. His name is Stratos +30-693-9906099 cell, and +30-2251-400460. Since you are in Greece, shipping would  simple.

Also make sure that you are getting to the correct pressure before the pump starts and stops to eliminate the possibility of an issue with the setting on the off/on pressure settings.

Happy Sailing;
