I would be carefull you are not adding too much PSI to your system. You could overcome any increased PSI by opening the hose bib only as much as needed and watching your pressure gauge, but that might result in slow fill time. What I did was plumb a 1 inch line to a hose bib, above that a ball valve and above that a 1 inch barbed fitting that I then run a 1 inch braded hose directly to the pool. With this set-up I have water from the hose bib I can use for diluting chemicals or whatever, but I also have a 1 inch line that fills the pool with some serious speed.
