Hi, just wondered if anyone can offer me any advice. I have a Sprite Quattro with end washroom, it appears that either the hot or cold water pipe has sprung a pinhole leak where it passes either under the shower or under the toilet. Does anyone have a recommended method to attack this? I don't really want to have to remove the locker where the cassette toilet goes. I was wondering if I remove the actual housing around the shower valve if that might be easier even though I might have to replace much more pipework. It is a bit of a shame as the Sprite us 7 years old and has been an excellent van to date, I am wondering if it might be caused by a burr that is visible on the plastic moulding under the toilet, which will be really annoying as it would be a 10 second job to have done this at manufacture. Thanks in advance for any advice.
