How To Replace The Delta Faucet Stem

The first thing you will want to do when changing the faucet stem is to make sure that the water to the faucet is turned off. You can shut the water to the faucet by shutting off the supply valves or simply shut the main water supply to the kitchen.

Step One: Removing The Faucet Handle

The first thing you will have to do to replace the Delta faucet stem is to remove the faucet handle. If your hot water stem goes bad you should also replace the cold side and if the cold side stem goes bad you should also replace the hot side. This is not necessary but you might as well change the opposite side to ensure that the faucet will not leak from either side. You can remove the faucet handle by removing the Allan key set screw that is in the side of the Delta faucet handle. You can see where the set screw is by looking at the Delta parts diagram on this page.

Step Two: Removing The Stem From The Faucet Body

In order to remove the stem from the faucet body you will have to remove the lock rings that are shown in the diagram below. You can do this by turning the lock rings to the left (counterclockwise) with a pair of channel locks and you will want to keep turning them until the lock rings can be removed. Once you have removed the lock rings you will be able to remove the faucet stem. Then you will want to replace the worn Delta stem with a new replacement Delta faucet stem and re-assemble the faucet stem and handle.

How To Remove The Faucet From The Sink

If you need to remove the entire Delta Faucet from the sink you can with a few steps. The first thing you will want to do is shut the valves off that supply water to the faucet. Next you will want to disconnect the faucet supply lines from both the supply valves and also from the faucet stems. You can remove the basin supply nuts with an open end wrench.
