I bought their Hanover 529 pull down faucet. BOTH quick connect fittings (hot and cold supply lines) leak. The people on the toll free number offered to send me replacemnt parts. I declined, and instead am taking the unit back to the store for replacement. Needless to say, I will NOT be buying a Pfister faucet this time.
hold the washer at the end of the coupling (use a tool if necessary) - push it inwards (opposite to the direction you want the water line you want to come out towards) and pull out the water line. That's it.

Turn the power back on and test the AC system to ensure it is working properly.
