How much 3/4 inch PVC pipe do I need to remove to install a union? Trying to fix a hole in a line. Thanks

Lately I've been using these. Dig around the pipe, cut out the hole / break, slip this on, and tighten down. They work great!

Put the union together and measure total length. Then measure how far the pipe goes into the the ends add this together and subtract total from the length of the union. The answer will be amount you need.

I've used these before. They are the only way to do it.

They make a union that does not have a stop in it, you slide it on the pipe add glue and slid it back over the other end of the pipe. Cheap and fast.

I would use a Sharkbite fitting. I think they have one you can push the whole fitting on to one of the cut ends and then push it back the other way to cover the joint
Sharkbite fittings

Looks like you've got your question answered.
Another thing folks may not be aware of is you can transition from PVC to galvanized pipe with a good Dresser coupler, I"ve done it a number of times. EGBinOR

Do what LenND suggested I do that on copper pipe when you can't move it. I'v even installed new single lever shutoff valves using a sweat union and a sweat coupling.

There is also an expandable fitting. Glue one end, slide the fitting together, pull out to where the other end of existing pipe is. Glue in place. Made for pipe that cannot be moved for slip fit version.
Also, might look at repair coupling that can slip over one side then back to cover both ends. No glue. Compression only.

Those things look like a great idea, but I know of two that slowly slid apart. Both were in the open (not buried) - one in a basement, which resulted in water damage to lots of stuff, and the other in a pumphouse, which amazingly didn't seem to hurt the pump. The guy in the plumbing section at the local Lowes store sez "don't trust them - lots of them have failed". Maybe failed from improper installation, but how much more simple could they be. Both of the failures that I'm aware of were placed in lines that had a 90 degree bend. In a straight section, well supported, or buried, they "should" work good. . .
