  • Delta single handle kitchen faucet

    I've rebuilt the valve assembly of my Delta single handle kitchen faucet. I am perplexed, however that the handle has to be slightly to the left of down in order for the faucet not to drip. If the handle is pushed to what seems to be "off" (or straight down) there is quite a small stream of water coming from the faucet.

    The only thing I can think of is that somehow through the years the stainless steel ball was replaced with one that may not be correct; HD seems to sell rebuild kits for different types of steel balls (#70, etc). How would I know which one to purchase, if the one currently installed isn't the correct one?

    The only way your question can be answered is to know the exact model.

      There is only one ball for the old style single lever Delta kitchen faucet
      and that is the RP70. The other one, RP212 is for single knob handles, typically found on some older lav faucets and tub valves. Hopefully, you
      also replaced the seats, springs, cam assembly and adjusting ring when
      you serviced the faucet. If not, then do so. If you did then it could be
      that the adjusting ring (found in the bonnet nut) needs to be tightened.
      Or the lever handle is not centered on the ball stem.

        make sure you get DELTA replacement parts, not some knock-off brand.

          Try tightening the cap threaded bushing located at the top of the cap assembly.
