Broken shower diverter

$title$

A tub/shower diverter is a small but important part of your bathroom plumbing. It’s responsible for directing water flow between the tub spout and the showerhead. If your diverter is not working properly, you may not be able to get water to flow out of one or both of these fixtures. Fortunately, fixing a tub/shower diverter is a relatively simple task that can be completed in a few minutes.

The first step is to identify the type of diverter you have. There are two main types: push-button diverters and lever diverters. Push-button diverters are the most common type, and they work by pressing a button to change the water flow. Lever diverters work by moving a lever to change the water flow. Once you have identified the type of diverter you have, you can follow the steps below to fix it.

Identifying the Problem

Determine the Type of Diverter

* Pull-up Diverter: Features a knob or lever that you pull upwards to switch between tub and shower modes.
* Push-button Diverter: Has a button that, when pushed, diverts the water flow.
* Rotating Diverter: Turned like a dial, rotating it allows you to switch between modes.
* Cross-handle Diverter: Two handles control the flow to either tub or shower.

Check for Obstructions

* Hair, soap scum, or debris can block the diverter valve, preventing it from functioning properly.
* Inspect the diverter outlet for any blockages and remove them with a brush or small object.

Examine Valve Seat and Washer

* The diverter valve seat is the part that seals against the washer when the diverter is in a certain position.
* Over time, the valve seat may become worn or damaged, causing leaks or improper diversion.
* Similarly, the washer may deteriorate, reducing its effectiveness and leading to problems.

Inspect O-ring or Packing

* A diverter may have an O-ring or packing that seals the valve.
* If this seal becomes worn or damaged, it can cause water leaks or affect diversion functionality.
* Check the condition of the O-ring or packing and replace it if necessary.

Consider Water Pressure

* High water pressure can put stress on the diverter and cause problems.
* Check the water pressure in your home and adjust it to an appropriate level if it’s too high.
