The following simple steps will help troubleshoot a leaking compression or stem-type pullout of your Pegasus faucet.

  • Shut off the water at the water supply valve. You can usually find them under the sink. Sometimes you can also find them on the wall behind the shower assembly. There, you can find them in a cabinet behind a removable panel.
  • However, if there are no localized shutoffs for Pegasus faucet removal, you must use the building’s main water shutoff.
  • Now turn on the faucets to let the water in the lines drain before you begin disassembling the Pegasus faucet.
  • Once you’re done with that, remove the faucet handle. You can do this by removing the screw and then lifting or shaking the handle.
  • Now loosen the lock nut inside with a wrench. Once the nut has been loosened and removed, remove the stem.
  • With some types of Pegasus faucets, the stem itself can be threaded into the body of the faucet assembly. In that case, you will have to turn it counterclockwise to loosen it and remove it.
  • For Pegasus faucet disassembly, now, replace with a new washer. Take the stem to your local hardware or plumbing supply store and choose the replacement washer that fits properly.
  • Reassemble stem and Pegasus faucet assembly in reverse order
  • Turn the water supply back on and test for leaks.

As you can see, it’s not that difficult. However, you need to make sure that you follow the steps above with due care.
