Angle stops are considered full open valves, not for volume control though its done often.
PRESSURE REDUCING VALVE....ben srI actually just installed quarter turn valves because when I went to shut off the valves they leaked incredibly. I am guessing that they were 20 years old. So after spending money on replacing the valves, I don't want to do anything that would cause the new ones to leak. Maybe a water saving aerator is a good option. Will the quarter turn valves get damaged quickly if they are shut half the way?
Thanks for all the answers.
