I am having trouble with low water pressure in my kitchen faucet. It started happening gradually over timeIt is a single-handle, with a sprayer nozzle. From reading other posts here I'm pretty sure its a diverter valve...bear with me as I've never done any sort of work on my sink. The house was built in 1993 so I'm assuming it was installed somewhere around then.
Since I thought it might be a diverter valve and I don't know what I'm doing I set out to find a manual for the faucet on what parts I might be looking for and instructions on fixing it. There's a "Kohler" stamp on the side of the sink itself so I assumed that it was from them. I contacted their support and uploaded pictures of the sink through the Kohler contact page who in turn said that it was not a Kohler faucet.
Side question: Can you have one brand of sink and another brand of faucet?
So I have some pictures of my setup and am hoping someone might be able to either help me identify what I have and/or help me with what I might need to replace or do to fix this. Or suggest that I just call a plumber.
I think this is the diverter valve?
I've created a full album of the handful of pics for this on Flicker if interested. There's also a video of how the water pressure is working here: video of low water pressure
