Faucet Repair

Q: My faucet drips even when I turn the handle all the way off. How do I make it stop dripping?

A: Identify the type of stem in your faucet:

  • If you have a 2 or 3 handle faucet with a primarily brass stem, try replacing the faucet bibb seator the stem bibb washer. If that does not resolve the issue, then replace the stem. Use ourFastFinderto identify your stem.
  • If you have a single-handle faucet with a cartridge, replacing the cartridge usually resolves a dripping faucet.
  • If you have a single-handle faucet with a faucet ball, replacing the seat washers and springsis the 1ststep to fix a dripping faucet.


Q: The water flow from my single-handle faucet is very low, what could cause this?

A: Sediment build up is a common cause of low water flow. There are 2 possible remedies:

  1. There could be sediment built up in the cartridge. Turn off your water supply, remove the handle and cartridge, and then flush the cartridge under clean water. Reassemble faucet in reverse order, turn on the water supply and check for leaks.
  2. If your faucet has an aerator, there could be sediment build up inside the aerator. Cover or close the drain so not to drop small parts down the drain. Remove the aerator, then remove the screen from the aerator. Clear any buildup on the screen. Reassemble the aerator and replace it back on the faucet. If this does not resolve the issue, you will need to replace the aerator.


Q: The stems I put in my sink faucets are reversed! What did I do wrong?

A: This is a common mistake. The stem packages should be marked Hot and Cold. It is possible when the stems were replaced, they got mixed up. You can remove the stems, swap sides, and reinstall per the installation instructions. To identify the direction of the stem, if a stem turns counter-clockwise to close, it is the cold stem. Hot on the left, cold on the right. This should resolve the issue.


Q: How do I remove a retainer ring from a stem? It seems to be on very tight.

A: For a Delta single-handle faucet that uses a cartridge or ball, we suggest using pliers or an adjustable wrench to remove the plastic adjusting ring, turning in a counterclockwise direction. You may need to use a very small amount of lubricant to assist in loosening the adjusting (retaining) ring. Be cautious when turning as not to break any parts or injure one’s self.

 For a 2 or 3 handle faucet, to remove the nut holding the stem in the valve (sometimes referred to as a collar), turn it counterclockwise with a wrench until the nut frees from the threads on the valve. Lift the nut up and over the stem. You may need lubricant if the nut appears to be stuck.

Tub Repair

Q: I have a trip lever drainin my bathtub, but the drain won’t shut when I lift the lever. How do I fix it?

A: There are a few options to fix this issue:

  1. Replace the linkage assembly with the PartsmasterPro Tub Drain Linkable Assemblyif the trip lever is working properly but the drain won’t shut.
  2. Replace the Trip Lever Overflow Plate, if the lever is not working properly. It is possible the spring has broken and the overflow plate needs to be replaced.
  3. Switch your bathtub drain to a Lift and Turn Bath Drain Trim Kitor a Tip-Toe Bath Drain Trim Kit. With most bathtubs, you can easily switch between the different drain trim kits based on personal preference.


Q: When I use my shower, there is water that flows from the diverter tub spout. What would cause this?

A: The seal in the diverter may have become worn or dislodged. You have 2 options:

  1. Replace the diverter in the spout. Check out ourPartsmasterProDiverter Gate Repair Kit.
  2. Replace the entire tub spout. PartsmasterPro offers a variety of tub spouts to suit most needs. Click HERE for our tub spouts.


Q: The universal replacement spout I bought doesn’t fit my tub. Why is this? I thought UNIVERSAL means it will fit anything.

A: Due to the variety of plumbing connections and faucet manufacturers, no one tub spout can replace every possible installation. Universal will fit most applications and connection types. If a universal tub spout won’t fit your tub, it is suggested to see if a replacement is available from the maker of your faucet.
