Bathtub Spout Shower diverter And its Working

You use a bathtub spout shower diverter daily but you certainly don’t understand what it’s called.

A shower diverter is a device that diverts water from the bathtub faucet to the showerhead. To channel water in the appropriate direction, you can choose among two locations.

You can fill your bathtub or use your showerhead from the same bathroom fixture with this small device. Isn’t it convenient and ingenious?

 A button or a faucet handle is used to activate the shower diverter. This handle is usually found between the hot and cold knobs on the bathtub. Water flows directly via the tub faucet while the shower diverter is open.

You close the valve by lifting the knob or lever when you wish to shower. The water is forced higher and out of the showerhead by pressure.

Tools and materials required to replace

The things which we need to replace a bathtub spout shower diverter are.

  • Screwdriver with four functions
  • A wrench that can be adjusted
  • Gun for caulking
  • Wrench for internal piping
  • Cutter for tubes
  • Nipples
  • Caulk made of silicone
  • Spout
  • The tape should be threaded

Follow the steps below.

Remove the existing nipple

With a pipe wrench, detach the old nipple. Use an “internal” pipe wrench if the nipple is too small to grasp with a wrench.

Replace the nipple with a new one

Bathtub spouts can break down in one of three ways: First, the tub spout diverter can wear out, allowing water to flow freely instead of being diverted to the showerhead.

Enclose thread tape around each edge of the replacement nipple and screw it into the wall fitting. Apply silicone caulk all around it and screw on the new spout. 

Second, when the spout screws onto the pipe, the threads inside the spout can split or corrode. Water might then drip inside the wall as it runs along the pipe.

Eventually, the finishing of the spout may flake or corrode. The setscrew could be relatively small and more difficult to see from the one pictured; you may need a headlamp to find it.

It’s simple to replace a slip-on spout: Simply unscrew the setscrew (typically with a hex wrench) and pull the spout away from the protruding copper pipe.

Pull gently while twisting the spout to avoid loosening any pipe attachments inside the wall. Then adjust the setscrew and slip on the replacement spout. It’s a screw-on spout if it doesn’t have a set screw. 

To disconnect the old spout, turn it counterclockwise. If the pipe protruding from the wall has a threaded fitting, just slice it off with a tubular cutter and replace it with a fresh slip-on spout (Photo A).

You’ll need a replacement screw-on spout if the pipe flowing through the wall is steel.

Spout Types 

These are three significant types of spout.

Slip-on spouts

Slip-on spouts are designed to fit over 1/2-inch copper pipe and are secured with a set screw. This “universal” model also features internal threads, which can be screwed onto the threaded pipe.

Screw-on spouts

Screw-on spouts have threads that run the length of the spout. They can be connected to a steel pipe or a copper threaded fitting.

Spouts with threads on the back end that screw on

Threads on the back end of screw-on spouts are possible. The majority of them come with a bushing that allows them to fit either 1/2-in. Or 3/4-inches pipe.


How to replace a bathtub spout shower diverter. A faulty shower diverter is a relatively typical and straightforward plumbing issue.

However, not resolving the problem results in water waste and insufficient water flow from the showerhead.

Basic plumbing knowledge and the time it takes to clean, fix, or replace the diverter is required.
