Disadvantages
• No room for mistakes – once a pipe has been soldered, you would need to cut the actual pipe to make any corrections to the assembly
• Soldering is an expensive process
• It takes a while to cool down, which could result in delays until work can resume. NOTE: Do not shock cool( apply cold water to the joint once soldered), as this can cause fracturing of the joint
• A certain amount of knowledge and expertise is required to solder
