Good day folks, I have a little problem.

Our kitchen sink faucet all the sudden lost pressure. About half. For no reason at all it seems, I did a visual inspection underneath, the hot and cold water are on full max, the stainless hose that the faucet detachable spray nozzle is connected too, is not kinked nor blocked. There is nothing visually that seems to have caused the sudden low drop. The face of the nozzle that has all the spray pattern holes in it, is clear and clean, no deposits blocking the flow, it's a pretty new faucet, I installed earlier this year. The rest of the house is flowing fine.

Any ideas?

Once I shut the water off to change a faucet and experienced the same thing.  Turned out the gasket on the shut down valve had some type of paper gasket that stuck to the seat and broke a section loose.  When the water was turned on it would get stuck over the valves exhaust side causing low water flow for the cold water only so the hot water worked fine.  Pain in the butt to find.  If it is both hot and cold, I would have to believe the problem/obstruction is inside the faucet itself.

Dan, thanks for that, yep, the flow is low in both hot and cold. Man I'd hate to remove that faucet if I had too, it was such a pita to remove the old one and install this new one, the space is so tight for my fat a*#. And to get my arms up there and work the nuts loose, man.

I hope I can fix the issue from the topside.

I would take the faucet apart and look for something stuck after the mixer.

Ya I'll start there, perhaps a new valve too if they stock em at the big box.

Before you take it apart, did you turn the faucet on with spray head disassembled to check the pressure?

Is this an electronic controlled on/off?

 

Most faucets have a lifetime warranty.  You might try calling customer service.  Some of them pretty good at diagnosing and will send new parts quickly.

Replaced a friend's faucet with similar problem.  Found the hose had collapsed inside.

Hey Gunny, did the hose appear normal from the outside?

No it's not Lew. Speaking of which, having issues with our touchless toilet flushers too, speaking of electrical, I hate those danged things!

I'll do that for sure Lew.

Welp, fixed it! I started looking at the actual spray nozzle per Lew's suggestion, and it looked pretty clean. So starting from the tip and working my way down, I took the nozzle off, and turned on the water and it came out full pressure from the hose, so there we have it, problem in the nozzle. Then I started looking closer inside the nozzle and saw a piece of black rubber stuck in the 1/4" diameter filter connection and it was plugging up the works. Removed it, re installed nozzle, and she works like a champ. So that explains the sudden drop in pressure, it detached from somewhere and shot up into the screen and plugged it all up.

I don't know why I do this most the time, I'm pretty good at fixing things but I automatically go straight to doom when these issues arise, I automatically have in my head me calling the plumber out to replace the whole faucet because I don't want to get back under there again, it's hell under those tight spaced cabinets. And I'll dwell on it for a couple hours, then I come on here and ask you all, and as you all alluded too, twasn't nothing, just a small blockage, done.

Thanks guys.

Thanks for the update.  Cool beans.

And that was the problem Dan, thanks sir!!!!

I was even having nightmares of a broken water line in our kitchen under the slab, see what I do to myself!?

I believe @Gunny calls it "paralysis by analysis".

Hey John. I guess it  helps to have these woodworking plummers on board.
