I'm putting in a pool and wanted to know if it is worth the effort to replumb my hose bib from 1/2" to 3/4" copper supply? I realize it will deliver more water but in a meaningful way to fill the pool?
TIA

Assuming you repipe back to a reliable starting point, 3/4 copper would deliver approximately 2 1/4 times at much flow as 1/2". SO if your pressure gave you 7 GPM thru 1/2" you should get 14 GPM thru 3/4. The pool would fill twice as fast. In my example a 20,000 gal pool would fill in 24 hr or 48 hr.

It will not deliver one gallon more water. The opening inside the 3/4" hose bibb is the same one that is in the 1/2" one and both of them are about 1/4 the size of a 1/2" copper line. And it is a very slow way to fill a swimming pool, unless you have more than one hose faucet and lots of hoses.

If you're going to replace the 1/2" line with 3/4", you would keep the inside diameter full bore for the entire run by using a full port ball valve with a 3/4" male X hose adapter. That's the way it's done around here or the 3/4" pipe is brought right over to the pool and positioned to fill the pool under the diving board, (for built-in pools).

It depends. The capacity of the water delivery is determined by several factors.
Water feed supply: do you have a 1/2" galv. pipe feeding your house at 20 PSI. or, 1 1/4" copper at 80 PSI. Do you have a old weak well pump that delivers 3 GPM. at 15-25 PSI. or, a slamming new pump that delivers all you could want at 40-60 PSI. Or, what will your well deliver without running dry?
Water delivery in the house is determined by friction loss. Every piece of pipe that touches the flow of water to the hose adds friction loss (-PSI), This loss is determined by a factor of flow and the pipe. The higher the flow the higher the loss.
Whether it is to your advantage to go with 3/4" feeding the hose bib could only be determined onsite. Generally yes you will gain by going bigger. How much, and whether the gain you will get if worth it, I can't tell from here.

Well, a bit of differing opinions!
I can tap into a 3/4" line near my main, and run 3/4" straight to the hose bib (about 35' total). I'm on city water and have about 60 psi. Using largest ID hose I can find, I assume that it should give more water. Any thoughts with this information?
TIA

Fire Dept doesn't do it here we have Pool Water Trucking Companies they use worn out gasoline tankers.

The larger hose will give more water due to the reduced flow restriction, but my opinion about the hose valve still stands.

Good choice now off to get the boat ready. I've got a hole filled with water I pour money in and I've got a hole in the water I pour money in. See how holes and water cost money?

Be thankful you don't have Paul Allen's "big" boat. It is estimated that it costs 20 million a year for crew and maintenance.
