I have a 1989 standard Delta single handle kitchen faucet with sprayer. (I have the original Installation Guide, which says it’s either model 100, 110, 300, 400, or 100HDF—I don’t see a model number anywhere on the faucet.)
The sprayer stopped working about ten years ago. I’ve finally gotten around to fixing it. Since the sprayer nozzle had also cracked, I started by buying a new hose and sprayer head assembly. That did nothing. So I bought a kit, and replaced most of the innards: seats and springs, O rings, cam assembly, and—most important—the diverter valve. It seemed easy, but did nothing at all. No leaks, but absolutely nothing from the sprayer when I squeeze it.
The old diverter (badly corroded when I took it out) looks a little different from the new one. It’s part brass instead of all plastic, and seems to be a slightly different shape. The old Delta Installation Guide lists the original part as #320, and there it is on the Delta website in brass, “RP320-Discontinued.” Is it possible that the new diverter doesn’t work in the 1989 faucet, and I need to get the original #320 part? If not, what else could be wrong? (I didn’t test the new hose/sprayer for obstructions before I installed it, but there wouldn’t have been anything I needed to do to clear the hose before installing it, would there?)
