Hey all, First time poster here. I've noticed my temp and pressure valve leaking hot water after I replaced the elements and thermostats in my AO Smith water heater. I am wondering, what would be the best way to go about replacing this. It looks like a simple cut the copper tubing, replace the valve and re-sweat it back together... My only problem is I've never sweat piping. I get the gist of how to do it, but don't understand where I would cut/replace add cupplers, etc... Any advice to keep this simple as possible would be greatly appreciated! Thanks in advance.
