    Peerless kitchen faucet low pressure?
    Hey there,
    I want to first off say thanks for any and all input on the matter its much appreciated.
    I have peerless model# p99578 it's the kitchen faucet two handles and one long neck up the middle. This thing has very little pressure when using hot or cold? It does however have great pressure on the sprayer and all the other sinks and outlets in the house have great pressure also. I took it apart and I couldn't see anything obstructing its way? I'm thinking it's the diverter guy up the middle? I have tried to take it out however I can't get it to budge? Its made of cheap plastic and I don't want to tear it up. I wanted to ask someone else before continuing to rip it apart. Could someone tell me what they think before the old lady kills me because she has no sink... Thanks again, Kris

    Hi Kris,
    Try this. Remove the aerator and check the screens for trash. While the aerator's off turn on the water. Full stream out of the spout? Let me know what you find. Tom

    Hey Kris,

    Shut the water off to the faucet and remove the knobs. Under the knobs you will find a brass nut. This will be the bonnet packing nut. Unscrew that and pull up the stem unit assembly. Check the stem unit assembly and the seats and springs inside for any crud or trash the maybe blocking the flow.
    Place a pan over the open faucet and turn the water on to flush out the inlet ports in the faucet. The supplies sound clear since you have pressure at the sprayer. Reassemble and test. Good luck, Tom

    The aerator at the very end of the spout is basically a faulty design.
    The teeny hole in the center of the top part of the aerator assembly
    Allows very little water through. I 'fixed' the problem by using the aerator
    Assembly (with some custom modification necessary) from my old
    Faucet, and voilą, it works like a champ!

    PS: Turns out that piece with the teeny hole can be removed! But I didn't
    Find that out till I tried to make the hole bigger. Then it snapped out! So,
    I put the original aerator back in sans the plastic disk with the teeny hole,
    And that worked too!

    That "teeny hole" is a water saver. It's there to cut down on the volume of water that's being used. They put them in shower heads also. Simply pry out and toss. Good luck, Tom

    I have the same faucet and the same problem (and apparently I'm not the only as there are a lot of these posts)! The aerator in mine did have several screens but removing a couple didn't fix the problem. We got a new aerator and that didn't work either plus when you take the aerator off and let the water run it is no better. So, it's NOT THE AERATOR!! We have taken this stupid thing completely apart many time and cleaned every single thing even the supply hose and soaked everything in vinegar (breaks up the calcium deposits) with no or almost no improvement. So, its NOT DUE TO MINERAL BUILDUP AND/OR SEDIMENT! I bought this faucet with my house so I can't use the warranty though I know the previous owner and am about to ask them if they have the receipt so I can try to use the warranty. Anyway this is really frustrating and irritating but I am determined to get to the bottom of it

    Hi Sonya. When you hadcthe faucet apart did you turn the water on for a minute to flush out the supplies and open valve body? Do you flush your heater on a regular schedule? Back to you. Tom

    Hi Sonya, I think I have your fix. Here is what we were getting out of our _brand new_ faucet with both taps wide open:

    I pulled the screen end off and popped out the plastic assembly inside (mind the rubber o-ring that comes with it). Note the vastly improved flow behind my hand... if taking the screen off entirely doesn't improve things, this won't either.

    That little hole at the top is the culprit. Stick a pen, pair of scissors, etc into it and pry... it pops right out:

    Put the funky bit back into the faucet.. the post in the middle holds the screens in place and keeps the water flow nice and controlled. Put the o-ring back in and put the whole assembly back together. Voilą!:

    We have two completely different peerless faucets, both purchased in 2008, and the process was exactly the same for both. Not sure how to fix the annoying drip you can kind of see at the rear of the end of the faucet... but oh well.

    I got peerless faucets with plastic inside and only brass nut I find is way at bottom of the faucets on the cover of the main part. How do I get the inserts out. Cannot find any brass nut directly under the knobs??

    I used a spoon handle to take out the diverter and found out the thing has a spring assembly inside. Store sells them for about 10 bucks, I wonder if they are really needed, seems like they might be some kind of anti drip mechanism

    I think she mentioned removing the aerator and it didn't work.
    Mine doesn't either.
    Buying a new faucet seemed to fix the problem. Strange how the hot and cold stopped at the same time?
    I wonder if it had anything to do with that plastic thing inside the base of the spout. My faucet doesn't have a sprayer but has this plastic thing, unlike other brands without sprayers. I have installed a lot of faucets(including this model) and this is the first time I have run into this problem.

    I have a 2 handle faucet with a sprayer. I have plenty of pressure with the spayer but very little at spout. I took the sreen off the end of the spout but still no pressure. I think that it is something wrong with the diverter. Can I take it out ? It appears to be not much more than a plastic sleeve inside the base of the rotating spout.

    I know this is an old post BUT I just wanted to say that <a href="https://www.plumbersstock.com/category/292/peerless-faucets/">Peerless faucets</a> have come a long way in the recent years. Along with Delta, Peerless is manufactured to have greater quality and better parts. I love the Peerless faucet I had installed about 3 months ago, it's still working like a charm!
