Most Delta faucets are either single-handle or double-handle which will need repair requirements specific for each type. 

Single-handle faucets include pull-down, pull-out, and static faucets with only one handle controlling water temperature and pressure. Meanwhile, double-handle faucets have separate handles for controlling hot and cold water.

Incorrect Installation

A reason why your faucet handle is loose may be because of incorrect components used when it was installed. Wrong-sized piping, screws, or other parts could cause faucet malfunctions.

Loose Set Screws

The most probable cause for your loose faucet handle is the loose set screws that are found inside the handle. These may cause your faucet to become shaky and lead to water leaks and other irregularities.

Loose Faucet Base

A loose faucet base can cause your loose faucet handle. With the base becoming loose, the rest of the faucet can be affected, leading to multiple problems such as leaking water and — you guessed it — loose handles.

Worn-out O-ring

Some faucets have O-rings that help keep the faucet handle in place. The O-rings may get worn out after years of usage, leading to a loose handle. When this happens, a replacement might be required to completely fix your faucet handle.

Locating The Set Screw

Inside the faucet handle, there is a set screw that controls the tightness or looseness of the handle. Delta faucets can have traditional or decorative handles. Traditional handles have set screws at the top or below the head while the set screw in decorative handles is located inside the cap.

You can use a flat screwdriver or tiny knife to open the cap of the decorative handle and find the hole hiding the set screw.

Tightening The Faucet Handle

After locating the set screw, use the appropriate hex wrench and tighten the set screw by twisting it clockwise until tight enough. However, don’t make it too tight that it will become challenging to operate.

If you feel like it’s still loose even after tightening it, try loosening the set screw by twisting your hex wrench counterclockwise. Afterward, check if the set screw is properly lined up, then retighten the screw until tight.

Reassemble your faucet, check for leaking, and make the necessary adjustments before turning on your water supply. If your faucet handle is no longer shaky and loose, congratulations, you have successfully fixed your faucet!

Can You Replace The Delta Knob With A Lever?

Yes, you can replace your Delta knob with a lever handle. However, you need to make sure that the lever will be compatible with your Delta faucet to ensure a perfect fit.

If you have a non-DIAMOND Seal Technology model, you can convert the single-handle sink, tub, or shower faucets to a lever handle. Still, you will need to replace the ball valve in the faucet for the lever to operate properly.

On the other hand, if you own a DIAMOND Seal Technology model, you will not need to replace the ball valve. You can simply remove the knob handle and replace it with a lever. You can refer to the faucet’s parts diagram to find the lever handle appropriate for that faucet.

How Do I Get My Free Delta Faucet Parts?

According to the Delta website, you can get a free faucet parts replacement as long as it is during the warranty period.

You may call their Customer Service number 1-800-345-DELTA (3358) and talk with a representative about replacement parts under warranty. You must provide proof of purchase, such as your original receipt, and have an acceptable reason why the faucet parts should be replaced.

All Delta faucet parts are warranted to be free of defects in material and workmanship for a period of 5 years.

How Do You Remove A Delta Faucet?

To remove a Delta faucet, start by turning off the water supply to your faucet. Then, if your faucet has screw-on retaining plates, get a Phillips screwdriver and unscrew all the plates. Once all the plates are off, you should be able to remove your faucet.

There are also faucets that are held by brass or steel retaining nuts instead of screw-on retaining plates. In this case, you will need a basin wrench and loosen the nuts from under the sink. Once you remove the nuts, you can remove the faucet.
