What is a Shower Diverter Valve?

Most homes have a shower diverter valve, but do you know what your diverter valve does? The answer depends on where it's located.

Understanding shower diverter valves

So, what is a shower diverter valve exactly? It’s a crucial component in your bathroom’s plumbing system, designed to redirect water flow between different outlets. This simple device allows you to switch effortlessly between your tub faucet and shower head, or between multiple shower heads in more advanced setups.

The primary function of a diverter valve is to control the path of water in your plumbing. When engaged, it redirects water from its default path (usually the tub spout) to an alternative outlet (typically the shower head).

There are two main categories of shower diverter valves:

1. Tub-to-Shower Diverter: This type allows a bathtub to double as a shower, an efficient solution for bathrooms with limited space.
2. Shower Head Diverter: Found near your shower head, this valve lets you toggle between your main shower head and a handheld one, perfect for those hard-to-reach spots.

A closer look at the types of tub diverter valves

A tub-to-shower diverter valve makes your bath-to-shower transition as smooth as possible. Here’s a quick rundown of the three common types:

Three-valve diverter

This diverter valve is between the taps of a two-tap faucet. After using the hot and cold faucets to get the desired shower temperature, the diverter handle is turned clockwise to redirect the water flow to the shower head. Turning the handle counterclockwise returns the flow to the tub.

Two-valve diverter

This type of diverter has two L-shaped valves and can be located in the center of a faucet that adjusts water temperature with a single dial or between the taps of a two-tap faucet. After the desired shower temperature is set, turning the handle redirects water from the tub spout to the shower head.

Tee-diverter

This diverter is the part of the tub spout. The diverter handle simply pulls straight up, sending all water from the tub spout to the shower head.

Shower head diverter valves

Have multiple shower heads or are you planning to add some? Then you’ll need a shower head diverter valve. These handy valves let you switch between your standard shower head and a hand-held one with ease.

The best part? They’re beginner-friendly, come in various shapes to match your bathroom style, and are easy on the wallet. You can find them at most hardware stores, making shower diverter replacement or installation a manageable DIY project.

How to replace or install a shower head diverter valve: A step-by-step guide

Ready to give your shower a spa-inspired makeover? Replacing or installing a diverter valve is pretty straightforward, even for beginners. Here’s how to do it:

1. Remove your regular shower head. You may need a wrench, but it should unscrew fairly easily.
2. Screw the diverter valve onto your water pipe. Make sure you have a tight fit to avoid drips or loss of water pressure.
3. Place the original shower head on the diverter valve, again making sure you have a snug fit.
4. Install the hand-held shower head onto the diverter valve. Once more, make sure the fit is snug to avoid leakage.
5. Test the shower diverter valve by running water through the regular shower head. If it’s working properly, use the lever or button on the diverter valve to switch the flow to the hand-held shower head. As you test, make sure that neither shower head is leaking.
6. Test the diverter again the day after installation to confirm there are no leaks.

Remember, if things get too dicey, there’s no shame in calling in the Pros. Better safe than soggy!

Maintaining your diverter valves

To keep your diverter valve in top shape, a little maintenance goes a long way. Here are some tips to ensure your valve keeps working smoothly:

• Release the Pressure: After you finish your shower, release the diverter and let water flow back into the tub before shutting off the water. This reduces stress on the valve, extending its lifespan.
• Set Water Temperature Safely: Always set the water temperature while standing outside the tub. This precaution helps you avoid the risk of scalding.
• Watch for Warning Signs: If you notice water flowing from both the tub spout and shower head simultaneously, it might be time for a shower diverter valve replacement. These issues can signal that the valve is worn out or malfunctioning and may need professional attention.

How do I know if my diverter valve is bad?

Is your shower misbehaving? Here are some signs your shower diverter valve might be throwing a tantrum:

• Water flowing from both the tub spout and shower head simultaneously
• Significantly reduced water pressure when the diverter is engaged
• Unusual noises (such as squealing or chattering) when operating the diverter
• Difficulty in moving or adjusting the diverter handle
• Inability to fully shut off water flow to either the tub or shower outlet

If you notice any of these issues, you may want to consider repairing or replacing your diverter valve.
