1/2" Pipe thread question?

Question

I have a outdoors plumbing question. I moved my spigot and it basically fell right out of the junction (? - I don't know what it is called) that is permantly attached to the house plumbing. The spigot has 1/2" male NPT, but is just a *tad* smaller than the junction's threading. I am not sure how someone got it to stay in the first place. The threads in the junction seem to be fine and is defintly not 3/4" NPT, the 1/2" male just isn't that loose in the junction, but does slide right into the female.

It looks like someone loaded the male end with teflon tape and got the spigot to stay into the junction somehow.

My question is this: What is the solution here? As I see it, I have 2 possibilities. One is to totally block off this junction, but with what and what NPT size? The second is to get the right threaded spigot, but again, what size?

The junction in question has no external threads

Answer 1

Most likely, the threads are damaged all the way around. I would cut the main piping, and install a new one, using pipe unions on both ends. Unions can be purchased that don't require threads on the pipes being repaired. Then install new pipe, with a new spigot. Use a frost-free one if you live in an area where it would be beneficial...

Answer 2

The junctiopn could have been mis-threaded or the spigot may have been mis-threaded. Try a new 1/2" pipe nipple in the junction to see if it fits, if it does, get a new spigot.

Answer 3

A very simple answer.
A spigot or valve has a male thread that is different from pipe thread.
Go to the plumbing supply and buy a coupling from pipe thread to male valve.

Answer 4

Just buy a spigot that fits or load it up with Teflon tape again.

Answer 5

is the pipe PVC, or steel,? your not stateing that,
if its pvc then the threads in it are wore out ,
