Its a 58" dip tube with a 4inch coupling that screws in. Trying to unscrew and change but threads are stuck. Afraid I may break off. Any suggestions?
Thanks
I meant a picture of the nipple. I assume you are changing out the dip tube because it is broken. Those nipples are often hard to remove. What size pipe wrench are you using? The tank should be full of water, and you need either a larger pipe wrench, or a cheater (a piece of pipe) on your pipe wrench.
"They" also suggest inserting a 5/8" carriage bolt into the nipple to avoid it collapsing. ( Same as removing anode when it's part of the hot water outlet )
