My 12 year old State water heater needs replacing and I have a question regarding the hot and cold water pipes up on top. I have attached a picture and would like to know how I go about removing the copper pipes and re-attaching them to the new heater. Should I cut the copper pipes just above the top Shark Bites and maybe use a flexible line back down. I'm a newbie and just unsure how to approach this. Thanks for your help!
