Roto-Rooter Guide: Compression Faucet Repair

Is repairing your home plumbing a constant struggle? With Roto-Rooter, do-it-yourself maintenance just got a lot simpler now that you have access to all the resources, services, and products necessary to see each project through to the end successfully.


You will need the following for this project:


  • Flathead and Phillips head screwdrivers
  • Box cutter
  • Wash cloth
  • Slip-joint pliers
  • Heat-resistant grease
  • Custom valve-seat wrench


Use the following steps to correctly repair a compression faucet system:


  • First, ensure that both the hot and cold-water shut-off valves, located directly under the sink, are firmly twisted to the off position, cutting off water flow to the faucet spout.
  • Second, reveal the screws holding the hot and cold faucet handles in place by popping out the decorative caps on top with a flathead screwdriver or box cutter blade.
  • Third, use the Philips head screwdriver to completely remove both screws.
  • Notice how loose the handles are with the screws taken out. They should easily pull out of their position on top of the stem assemblies using little force.
  • Next, locate the retaining nuts holding the assemblies in place and, with a wrench, loosen both of them.
  • If loosened enough, the stem assemblies will easily slide out of their current position over the valve seats.
  • On the bottoms of each stem assembly, take notice of the rubber washers responsible for keeping the system watertight. If damaged at all, replace them with new ones that are the same size.
  • Now remove the assembly cover by undoing the packing nuts holding it in place. When the cover is gone, the stem shaft is visible. There will be horizontally placed rubber o-rings running up and down the shaft. With scissors, snip off any rings that appear brittle, cracked, or damaged. (If there are too many rubber pieces to replace, you can also replace the entire stem assembly with a new unit to save time.) Dental tools are very useful for removing o-rings too.
  • Heat resistant grease will help make it easier to slide the replacement o-rings into place snuggly.
  • Now, turn your attention to the sink again. With both fingers, reach into the valve seat openings and feel around for roughness. If the surfaces feel uneven and rough, the valve seats will need to be replaced. Remove them with a custom valve seat wrench and replace them immediately with new ones.
  • After the valve seats have been replaced, follow the previous steps in reverse order to reassemble the entire unit.
