I have a AGA 120 dual overflow tank. 48"x24"x24".
I need to replace the bulk head. I went to HD but they didn't have any bulk head. I'm about to order it online but not sure how to measure it.

I try to use the compress fitting at HD to figure out the size, it's like between 1 1/4" and 1 1/2". It looks like some odd size.

I also want to connect the bulk head to my piping in a way that I can easily disconnect my bulk head and my plumping without cutting any pipe. The reason I had this problem was the guy did the plumping connect a union to a pipe to the bulk head. There was no way to take out the bulk head when I move the tank without cutting the pipe. Now I have to do the whole plumping. I know it sounds a little complicated. I'll try again if this is not clear enough.

thanks in advance!!!
