Things you will need:


  • Flathead and Phillips head screwdrivers
  • Slip-joint pliers
  • Box cutter
  • Wash cloth
  • Heat resistant grease
  • Custom seat wrench (contact Roto-Rooter for faucet model details)


Use the following steps to properly disassemble and repair a compression faucet fixture:


  • First, locate the hot and cold-water switches underneath the sink. Turn both switches to the off position, doing this will cut off all water flow to the faucet.
  • With a box cutter, carefully pop the decorative caps off the top of each faucet handle. Underneath these caps, there will be a set of screws holding the handles in place.
  • Use the Phillips head screwdriver to carefully remove the screws from both handles.
  • After placing both screws in a safe spot, the hot and cold faucet handles should be fairly loose and easy to remove. Pulling upwards carefully, the handles should jostle free without too much force.
  •  Removing the handles from the faucet should reveal the stem assembly. With the slip-joint pliers, loosen the retaining nuts, keeping the stem assembly in place.
  • Once each unit is loosened enough, carefully pull them out and inspect the rubber washers on each end. These washers keep the faucet system watertight. If you notice even the slightest damage or warping to these pieces, they will need to be replaced in order to eliminate leaking.
  • Disassemble the stem assembly even further by undoing the packing nuts to uncover the rubber o-rings. These little pieces also keep water from escaping.
  • Remove damaged o-rings by snipping them off with scissors.
  • Make sure to coat the replacement rubber o-rings with enough grease so that you can slip them into place without too much trouble. Heat-resistant grease works best for this application. (One thing to keep in mind, if you notice that most of the rubber pieces are warped or damaged, is that you can easily replace the entire stem assembly to save time.)
  • Once the stem assembly issues have been resolved, continue on to the valve seat of the faucet.
  • With your finger, reach into both holes and feel how smooth or rough the insides are.
  • Excessive roughness means that the valve seats are no longer watertight and need to be replaced.
  • To remove a valve seat, see your local Roto-Rooter provider to purchase a valve seat wrench. Once you have a valve seat wrench, remove the bad valve seats by unscrewing them.
