I had two Truma regulators fail. The second one was bought by me and was less than 6 months old when it failed. Fitted a different make and since then, no problem. Now carry a spare regulator just in case.I have lost count of the number of failed regulators I have chucked in the scrap bin. Certain makes are really bad for being affected by oily deposits. Other, usually cheaper makes rarely fail
This is what we fitted second time.
