Carette compressor first problem after 4 years.

Guess what the compressor had its first problem after 4 years.

It seems the non-return valve malfunctioned and blocked the inflow of the high pressure into the oil water seperator.

The end-result was a mini explosion when the steel tube removed itself from the ferrule after a too high pressure buildup 💣

The culprit was the green rubber inside the non-return valve, it sheered off a small piece and that piece blocked the ingress of the high pressure air.

The repair :

• ordered a spare ferrule set and used it to reconnect the steel tube to the non-return valve.
• removed the green rubber part so it no longer can block the inflow

All is fine again. No leaking even with the green rubber removed... 😎
