When the water is turned on, the faucet "sputters" and "hammers" as if the water had been turned off then back on when it hasn't been. Plumber says we need new part (inside cartridge 070807-Aqua Source). Do you carry that part?

The USUAL cause of this is the diverter valve that channels the water to the sprayer. There are several types of these so search for yours in google to find a blow-up drawing of it. They are usually in the tower the spout swings on and sometimes are a pintle valve like a little rod with dumbells on the ends. Crud can make them not seat then they will cause the hammering.
