No kitchen water pressure

[Kidkraz]

Forgive my failure here, but I do not understand what this means.

I have attached a picture of the problem part from the center of the kitchen
faucet. I believe the center piece should move freely up and down, but it is semi-stuck.

I am not sure of its name, and can't find another.

Sorry for my prior posts from remote that were hurried, and with poor internet.
I will also say that I changed the anode, and some grid particles from the worn anode likely contributed to the sticking faucet part.

It's all in a day, right?

If you fixed the problem, good on ya! If you found grit with the assembly that is preventing that small part from sliding, I'm sure you can clean it out.

You might try back-flushing the spout. Using a small hose, or even a mouthful of water and a soda straw, force water into the end of the spout, and watch for grit to come out of the central body of the faucet (and onto your countertop).

If you are still looking for help, we need to know the manufacturer of the faucet assembly (Moen? Delta? who?), a model name or model number of the faucet assembly, and a good picture of the entire faucet assembly. The factory used many different faucets, and your photo above doesn't help us identify yours.

The diverter in the pic is a Kingston Brass KBRP 112D and it is sold by
kingstonbrass.com

I got the center piston working better by cleaning it with isoproply alcohol, but,
I ordered a new part because I could see that some of the plastic is worn away on the bottom, and it might fail again. Total cost via FedEx is $25.

For an on-the-road fix for this problem, a practical solution would be to remove
the center cap on the faucet stem, and use a small flathead screwdriver or needle nose pliers to lift the diverter up and out of the faucet.
Of course, that is after turning the water pump off and pressure down. After putting the center cap back on, and the water pump back on, the hot and cold water will work ok.
The sprayer hose will be getting only partial water pressure, so mostly useless.

I don't know if this faucet was original or changed out.
And, if ever needed, a 1 gallon water jug can be trimmed to fit perfectly into
the bathroom sink for transfer of warm water next door to the kitchen sink.
A little something learned is better than nothing.

and if your faucet is the same, well, maybe...

I cleaned the diverter as Bill advised, and put it back into the faucet.
Hot and cold water works, and the sprayer works, although I am not
sure about how it is supposed to work.

I will install the new diverter, all the same. The piston/plunger is still
not moving freely. The water pressure probably makes it move up and
down, if it can.

The faucet is actually an attractive chrome finish.
I can reach the cold water stem ok, but the hot water stem...

Happy Camping!
