The copper joint is leaking, and the tap water hose and copper joint are leaking
It is suggested that the material used for piping may be better. At least the same material
Because the water has temperature, and the thermal expansion coefficient of aluminum and copper is different,The coefficient of thermal expansion is different, that is to say, the interface is always moving (heat up, cold contraction),
1, the expansion of aluminum pipe is not expanded, and re - do the side.2, copper joints are non-standard products, replaced by standard parts.
