So we have just replaced a Pegasus tap system in our Kitchen with a Moen 'Finley' and although everything is hooked up and the water has been turned back on, we have no water coming out of the tap. Not sure why this would be. Any ideas?

Do you have water at other points in the house?

Remove the aerator, or if you have a pull out spray head on the unit, unscrew the pull out spray head off the hose (do not let hose drop down.. hold tight) and then turn water on. If water flows, clean the aerator and reinstall and should be all set.
