Help please!! Found a leak in the shower valve water supply pipe joint (cpvc to copper), leaking behind the shower panel into the interior of wall of bath. Please see video of leak here: https://drive.google.com/open?id=1RtvFQoFV0uG6X5tSGsVSaXjCxsGcshRi The leak has been stopped. Could not attach pictures, so I have added them in a reply to my own post. Please take a look. The shower valve is not braced. The supply lines are not clamped. This home is in California, built in 2009. I am perplexed this happened. Is it a code violation issue?
