sillcock

Looking for a good sillcock and opinions on the frost free type. The ones I saw at Lowes didn't seem to open well at the inside end.

Also I was assuming I would be running 3/4" to the sillcock but didn't see much selection. Is there a noticable differance between 1/2 and 3/4t" as far as pressure when using a hose?

Thanks in advance

3/4"

As far as the valve itself is concerned, it is usually the same valve with just a different thread on it. If you have a long pipe to it, then a 3/4" may give a little more volume, but only because of the pipe, not the valve.
