Am I wrong? Why do they have valves with small passages?

Maybe itís just the type Iím looking for - hose bib s. But they have them for 3/4Ē pipes / npt....

so thereís lots of water coming through the pipe. And even ball valves have stupidly small openings for the water to flow thru?

and this is usually where you do want high flow watering/sprinklers, etc.

and websites donít bother mentioning this. You have to read comments or gamble on the passage size?

When looking for valves pick one that say they are "full flow".

Thanks for your great info as usual.

But any thoughts on 'why' that should be needed - that you need to make sure that the valve you buy won't be a huge impediment to the flow?

Seems all the hose bibbs I saw at Home Depot and Lowes have this same issue - garden hose connection (so 5/8" or 3/4" hose on that garden hose connection - and tiny opening for the ball valve. The multi turn seem to have somewhat bigger openings, but that's jsut cause you can't see farther in there to see the smallest part.

I started looking at kluges - more expensive full flow valves with adaptors to get to the 3/4NPT on 1 side and garden hose on the other. way more than I wanted to spend and too bulky.

But I guess that's the answer - smaller ball is cheaper.

babaganoosh-

I think you can get somewhere around 23 or so gallons/minute through a 3/4 inch pipe in the normal house pressure range. I donít think there is any way you would need anything like that flow at a hose bib. So a hose bib that is somewhat restrictive as you are seeing, or a standard-port ball valve which is more restrictive than the full-port valve (as Pilot Dane indicated) Ė I donít think would have any effect on the water flow that you would want.

At least thatís the way it seems to me.

Could I be wrong ? Who me? Ė lol!

Happy Fourth!!!

My office was replumbed about 10 years ago. A frostproof sillcock from Lowes was used. The flow was horrible. Replaced it with a Woodford and the flow through the faucet was more than double. One peak inside the cheap faucet showed its tiny internal passage.

Wow- that is good to know. So then it really does pay to look carefully at the faucets.
