How frustrating is it when you want to shower with cold water, but hot water comes out? This usually happens for several reasons. American Standard shower valves also have this problem. So today, I will try to disclose why the American Standard shower valve hot and cold reversed.
This scenario often occurs for a few simple reasons. The significant reason is the hot and cold water control knobs are not installed properly. Also, it can happen if the shower cartridge is not aligned correctly.
But this is not the end. There are some other significant reasons behind this which are discussed later. So read the full article to know why this is happening and how to get rid of this issue.
Take a look at this table to get a quick overview of this issue. Hope you will understand the possible reasons and solutions.
|Wrong Control Knob Placement

|Both (Hot And Cold) Pipes Run Parallel
|Attach the line separately so that they are not touching each other.
|Replace the thermostats.
|Defective O-Ring Inside

If your American Standard shower valve problems occur, especially reversing water, you need to identify the reasons first. In addition, you should know the solution.
This issue will happen if you have dual knob temperature control setups in your shower valve. Generally, shower valve controllers have two sides. On one side is the letter “H” which indicates hot; on the other, there is the letter “C” which indicates cold.
So these two have different positions. But sometimes hot and cold reverse due to inconsistent placement of control knobs. Simply put, the hot control knob is placed on the cold side, and the cold control knob is placed on the hot side.
And because of this your hot water and cold water are reversed i.e. hot water is replaced by cold water and cold water is replaced by hot. This is due to the carelessness of the plumber. The plumber may forget to check or determine which is the cold side and which is the hot side.
Possible Solution: Fixing this issue is a piece of cake and fairly less time-consuming. This DIY task includes shutting off the water supply, inspecting the knobs, unscrewing the temp control knob, removing the knobs, and switching the control knobs.
Incorrectly aligning with the American Standard shower cartridge is the second and most common cause. It is considered one of the most intriguing culprits for cold and hot water reversal. Note that, if you have single-knob setups, this issue may happen then.
However, when the shower valve cartridge is not adjusted correctly, your entire relaxation like standing warm spray water will be disrupted. It happens because the cartridge can’t regulate the temperature perfectly.
Possible Solution: If you notice and inspect the shower valve cartridge is misplaced, replace the cartridge. Replacing is not a tedious task. This process includes removing the shower valve handle, freeing the cartridge, and replacing the cartridge.
When the hot and cold water lines of your shower valve flow in parallel, it affects their temperature. This means that your hot water will feel cold and cold water will feel hot.
Sometimes the hot water line touches the cold water line, causing it to heat up as well. The opposite can also happen. So this could be another significant factor. However, if this is the case, you must fix it.
Possible Solution: If you observe such inconsistencies, take the excess pipe apart. If you can’t, hire a professional plumber to do the job. Because if the plumber is not good, it is more likely that there will be mistakes in the work.
As you know the function of a thermostat is to adjust the temperature. With a thermostatic shower valve, you can easily pre-set the temperature so that you can take a relaxing shower with the desired water.
Frustrating but true, when your shower valve has hot and cold water reverse issues, assume a thermostat malfunction has started. This is because the thermostat may have become too hot, thus heating the cold water as well.
Possible Solution: Sometimes it happens for loosening the screw inside. But if the thermostat is damaged, you should replace it instantly.
The O-ring is another crucial object inside the shower valve spout. It usually prevents unusual leaks and keeps the water from leaking to serve the desired water. As it is on the cartridge and works as a sealer, it should be fixed soon.
Possible Solution: There is no solution except to replace the broken or damaged O-ring on the shower valve.
According to a user from iFixit, replacing is straightforward. It includes turning off the water supply, removing the handle’s middle side screw, taking off the escutcheon plate, eliminating the cartridge stem and related screw, and replacing the O-ring. Simple!
A pressure-balancing valve is crucial for every shower valve. It balances the water pressure and maintains temperature. But when the pressure-balancing valve starts to fail, the hot and cold water get mixed up or flow inaccurately.
Possible Solution: When this valve starts to fail, change it hurriedly. Otherwise, you can’t get proper condition water when taking a shower.
Another reason can be hot water issues. When the water temperature switches inappropriately, the water temperature will be changed.
In this case, if you face the shower mixer hot and cold water reversed, look at the water heater. So what do you do in this situation? The solution is to resolve the issue by inspecting the water heater and if needed, changing it.
