My Delta Single Handle Faucet #300WF will turn on the water by moving handle and sometimes it doesn't. Or it will turn on for a few seconds and then turn itself off. It doesn't matter what position I place the handle (hot or cold). I have installed the RP3614A Repair kit. That solved the leaking issues but the intermittent issue of the "no water flow" is a major problem for my spouse and me. )-: Does anyone know what the fix is?

Does the water not flow through both the spout and the sprayer or just not from the spout? There's a diverter valve the shuts off the flow to the spout when the sprayer is being used. It sounds like a diverter issue.

Holy Toledo, Batman/Steve!!! That is the problem. And we don't use the sprayer. Can you recommend a way to delete or disable the diverter valve? Or clean it? Or replace it with a new one?


Any help would be appreciated!

Turn off the water supply to the faucet. Remove the handle and dome. The spout assembly will lift off of the faucet body, exposing the diverter valve. The diverter valve just pulls out from the body and the replacement pushes in. There are 2 o-rings, #11 and 11A on diagram that you might want to replace. Put a thin smear of plumber's grease on the o-rings before pushing the spout back on. Call Delta and see if they will send you the new parts.
