    Low water pressure after faucet install
    I have recently put a kitchen area in my basement. After running the water lines (1/2" cpvc) and installing the faucet, I am only able to get a trickle of either hot or cold water. I disconnected the supply lines from the faucet and it seems like I have good water pressure through the supply lines and through the spray diverter. I have also tried a new faucet and I'm having the same problem. Any advice would be appreciated.

    Are you on city water or well? If it's a well what's the pressure gage say?

    Is there some gate or ball valves you didn't turn back on all the way when you shut the water down on that line?

    Take off the aerator at the outlet of spout. See if you have better pressure now. If so, clean the aerator and put it back on. Let me know if this helps.

    I agree with MGD77: it is most likely the aerator. Clean it, and reinstall it. Now, you should have enough flow...

    Maybe I'm missing something here. He even tried a New faucet. Mygrill Milo you think that maybe the Brand new faucet is already clogged or defective faucet? Mmmm

    Thanks for your help. The new faucet must have been defective, but I cleaned the aerator in the old faucet and everything works great!

    Thanks again.

    This is a mini history post here. All is correct in thoughts cool...
    A new kitchen is usually a new faucet, So when I read you when out and got a second faucet that was new and didn't work assumed that 2 new faucets bad would be unlikely. The 'old" was not mentioned that way.

    Glad it worked out.

    My fault. I neglected to mention that I used an old faucet on a new kitchen to save money. All of you were basically on the right tract, though. Thanks again.

    21Boat: sometimes, when you install new faucet - and open angle stops - the very first puff of water brings in debris from angle stops and clogs aerator. I always remove aerator and then turn water ON. I let it run for few seconds and than reinstall aerator.

    I usually purge before faucet goes in ,

    Especially if there was soldering done. Not everything goes through to aerator.

    Ruined a Moen in the early 80s when I shut the faucet off and crunch. Many times vertial lines are cut in a rehap and not dry capped. A good purge is in order without facuet

    This is the only reason I suspected aerator. If good pressure out of supply lines, and good pressure out of spray, it only leaves internal diverter and aerator.

    I agree 21, that lines should be purged before hooked to faucet, and I agree also with milo that fuacet should be flushed with out aerator installed, but I believe this is something that only tradesmen know to do. The two new faucets threw me off too, I just went with my gut on this one.


    Glad you got the problem fixed, Take care.


    Once again, great answers from both of you guys.
