If these straight connectors are flow regulators - http://www.doncasterkitchensandbathrooms.co.uk/Cartv3/Details.asp?ProductID=2891 - (presumably they have a narrow hole?) then surely all the ball valves I'm fitting as isolation valves are restricting flow too? I've been trying to get maximum pressure/flow rate, and now feel it's all been undone.
Are ball valves flow restrictors?

Every fitting restricts flow to some extent. Are the valves full bore?
FLow regulators have active elements inside which increase the resistance as the flow increases, so it "flattens off", if you follow, at the desired flow figure regardless of pressure.
They aren't perfect and they deteriorate, but they aren't too bad.
The "active element" is usually just a little rubber O ring being pushed into a tightening space.
Full flow isolators have "no" resistance, and smaller bore ones make no effective difference at low flow rates.
Bigger problem with cheap and nasty little isolators is that they're crappy, and leak.
