Yes that’s true but I think if the non genuine pipe would have been fitted correctly the first time by the garage the problem would not have occurred with it blowing out a few times I think it damaged the groove in the pipe but I guess we will never know. After sending the pipe back I was only expecting a part refund as I purchased the high pressure pipe and the return, I only sent the high pressure one back as the other was on the camper but to my delight I got a full refund
