I had a kitchen hot water hose which bursts this morning.
This is a new connection for a new kitchen tap only a couple of months. The plumber installed a white connector (similar to the one remaining on the top) to the isolation valve but it bursts to somewhere (probably behind the cabinet) this morning. What I am not entirely sure is whether this connection was correct? It seems to lead a very rigid connection (via the white coupler) which connects the water pipe with the flexible hose above. This is not in my area but I just feel something was not quite right. If not, what kind of connection is expected if I called a plumber for help?
Is this something that I can fix it by myself (e.g. to purchase a half connector if this is right approach)? What spares and tools that I may need? Thank you very much!
