I have ONE outdoor faucet that drive me nuts. I set a flow rate with it to adjust a sprinkler, and I come out twenty minutes later to find that the flow rate was cut in half ... sometime in the last twenty minutes. I readjust, and then come out later and find it AGAIN wrongly adjusted. My other faucets don't do this.

OK, I should replace that faucet. My question is, what kind of faucet should I look for that will maintain at least roughly constant flow? Is there some design that assures a more constant flow?
