FAQ - Showers

How can I make sure my shower is safe?
  1. To avoid dangerously hot temperatures, make sure your water heater is set at 120º F or below.
  2. Install a pressure balance tub and shower valve, such as those found in the broad selection of the Delta® Monitor® series.
  3. Set the valve’s adjustable rotational limit stop to prevent the temperature handle from being turned to dangerously hot levels.
  4. Test the tub/shower water with your hand before bathing.
I don't want to change my plumbing. What kind of shower can I get?

If you don’t want to modify your existing plumbing, you can get a standard shower, which you can customize by simply choosing your own configuration options. You can also get a jetted shower, which can give you that spa-like experience without requiring a major overhaul of your entire bathroom.

See Your Shower Experience for more information on the options available.

Is this anything I should consider when looking at custom showers?

Custom showers will usually have a higher water demand. Therefore you should design a configuration that will not exceed the amount of water the valve can provide, or that the hot water heater can support, or that and the drain can take away. It is best to work with an experienced designed and plumber when purchasing a custom shower.

What is a custom shower?

A custom shower is a combination of showerheads, body sprays and hand showers that you personally select to create the shower of your dreams. Designing a Delta customer shower is the perfect way to get your shower just the way you imagined it.

See Your Shower Experience and discover more information on the options available.

What is a jetted shower?

The Delta Jetted Shower™ is a semi-custom shower solution. It features a shower head and two spray jets with a revitalizing, yet relaxing, wide spray. You can add functionality by selecting the Jetted Shower XO (eXtra Outlet) and choosing an additional shower head, In2ition® Shower, XO Jet Module™ or hand shower.

See Your Shower Experience for more information on the options available.

What is the difference between 13 or 14 Series and 17 Series showers?

The 13, 14, and 17 Series showers all use Monitor® pressure balancing valves for safety. The 17 Series has the added feature of a volume control, while the 13 and 14 series offer temperature control only.

Many Delta series are also available in a 17T. The 17T Series uses TempAssure® thermostatic controlled valves.

Why does water come out of my shower head and the spout at the same time?

Most likely you are experiencing "shower-rise," where the water can’t get out of the spout as fast as it flows through the valve. This causes the water to back up and come out the shower head. There can be one of several reasons for this:

  1. The valve could be upside down.
  2. The length from the valve to the tub spout is outside of the 8" to 18" rule.
  3. There is more than one 90-degree angle.
  4. Something other than copper or galvanized pipe going to the spout was used.
  5. The most common reason is that there is something restricting the water flow to the spout (for example, solder or something lodged in the pipe). Something is impeding the flow of water to the spout and causing it to back up and go out of the shower head. If this is the cause of shower-rise, it is possible to remove the blockage by removing the tub spout, and then feeding a plumber’s snake or a speedometer cable up through the tub drop. The act of feeding it causes it to twirl and loosen the blockage. Be sure to flush the valve before reinstalling the tub spout. Be sure to check the tub spout itself for blockage.


If none of these help, you may need to call a plumber.  After the shower has been installed and the wall has been closed, there is little that can be done to remedy this situation yourself.
