Most of us find it challenging to take cold showers, especially over the colder months. It could be even more frustrating realizing that only your shower is not getting hot, but other points, as the sink does. 

Warn showers have many benefits, saving you from the unpleasant feeling of a cold shower. Most people consider showers a special session; they clean off the day’s filth and grime. 

Most hot water losses are a result of default in a water heater. Surprisingly, you may have hot water in the kitchen and laundry rooms. If this is the case, then this article is for you. 

This post will discuss ways to solve “the shower not getting hot water but sink does,” give the causes, and how to avoid them in the future.

How to Tell If Your Shower Is the Issue

Most people often assume that their shower is faulty whenever it’s freezing. Still, looking elsewhere is essential to see if another factor is at play. 

First, ensure the hot water is running in each sink. The problem likely lies within your shower if this is the case. But if cold water is coming out of every faucet in the house, it could be your water heater.

After checking off these boxes, you’ll know if the problem is with your shower.

Probable Causes of Your Shower Not Getting Hot Water But Sink Does

The problem with your shower not getting hot may be brought about by different issues, such as damaged shower heads, faulty valves, and clogged pipes. The solution may be as simple as replacing the shower head or more complex as unclogging the plumbing system

1. Faulty Mixing Valves

The shower’s mixing valve is why some showers fail to heat. The mixing valve is a control valve that regulates the proportion of warm water to cold water in the water supply, allowing you to shower at your chosen temperature. Adjusting the temperature of your shower’s knobs without a properly functioning valve won’t matter.

The mixing valve is concealed within the shower’s piping behind the wall, and it is not recommended that you remove the faucet’s handle or otherwise resort to using tools to gain access to it. The mixing valve may need to be replaced if this needs to be handled by experts. 

2. Failed Anti-Scald Device

Your showerhead may be equipped with a safety feature that prevents a sudden burst of scalding hot water from happening. Many contemporary faucets have an anti-scald device known as a “hot limit stop” or “rotational limit stop,” which, if set too high or breaks, may prevent nearly any hot water from flowing through the showerhead. 

To repair or reset the showerhead, you must take it apart. Misusing this device can result in a scalding hazard; not all showerheads are equipped, so we advise calling a plumbing professional to complete this task.

3. Shower Cartridge

The cartridge for your shower is a part of the shower handle itself. These cartridges are the final line of defense in regulating the temperature of your water supply.

Shower cartridges function as mixing valves, blending hot and cold water to the setting on the shower’s handle. In contrast to the mixing valves common in older homes, shower cartridges offer a more up-to-date solution.

Depending on the supplier’s quality and how well the cartridge is taken care of, a shower cartridge can last anywhere from 10 to 30 years.

4. Worn Out or Faulty O Ring

O rings are often overlooked despite their crucial role in our water infrastructure. These rubber washers ensure that all of our plumbing connections are leak-proof.

Leaks can form due to the cracking of these rubber rings over time. A cold shower may result from water leaking around the thermostat or a major cold water leak into your hot water.

5. Corroded Pipes

Rusted water pipes, frequent in older homes, may cause poor water pressure in an upper bathroom. Galvanized steel pipes’ internal corrosion speeds up when hot water is present, thus limiting water flow. 

Even copper pipes can become clogged with mineral buildup from hard water. There is no simple way to replace the pipes to have the water flowing again.  

How to Fix My Shower Water Not Getting as Hot as My Sink

1. Inspecting Your Mixing Valve

It’s best to give your mixing valve a once-over before replacing it. You’ll likely find your mixing valve in the middle of your piping and water heater.

You should fasten a thermostat in a circle to your mixing valve. You can test the thermostat while the water is running. If the thermostat reads low, but the water is still cold, it may need to be changed; if it reads high but is still frigid, it must be replaced.

2. Monitoring or Adjusting the Anti-Scald Device

Removing the handle lets you determine if the shower has an anti-scald device. These accessories are close to the shower’s handle, typically manufactured from plastic.

You can detach the gadget from the handle and remove it manually. After you take it off, turning the gadget to the right will let hotter water into your shower.

3. Changing O Rings

An O ring’s lifespan is from 15 to 30 years. A leak can be easily detected by pouring water through the pipes as you inspect them once a year.

In the absence of rust or other apparent deterioration, an O ring is often the source of leaks in plumbing systems.

You should shut the water off before the leaking plumbing connector can be dismantled and the old O rings replaced with new ones.

Your faucet may only have one handle because the diverter seal, an O-ring made of rubber that prevents water from seeping out of the lever when turned off, is worn out.

4. Changing a Shower Cartridge

you can swap out shower cartridges faster than mixing valves and respond more to rapid temperature shifts.

You may get to the cartridge in your shower after disconnecting the handle in several ways. You can pull out many shower cartridges with your fingers or a pair of pliers, but a few brands call for specialized equipment.

After removing the old cartridge, you can install the new one and reassemble the device.

Low-flow showerheads provide the same level of shower performance while using less water. Additionally, they have various settings to customize your shower experience.

How to Reset an Electric Hot Water Tank in Two Easy Steps

There’s a chance that the unit’s reset switch tripped, which can happen with electric hot water tanks. Those switches sporadically activate now and then. However, this is frequently the case because:

  • The thermostat in the unit is broken.
  • There’s a problem with the reset button.
  • The high-limit switch, which usually stops the water from getting too hot, has stopped functioning.
  • There need to be more heating elements.
  • A connection has come unclipped.

Remember that the restart button on the water heater has an important job: it turns off the power if something goes wrong, like a power surge or a broken thermostat. 

Repeated power outages to your hot water tank indicate a problem that requires the attention of a licensed Calgary plumber. Also, combining water and electricity can be harmful. Always get the advice of an expert before proceeding.

Where Is the Mixing Valve In My Shower?

Hot and cold water use a shower mixing valve to generate the ideal bathing temperatures. This can be changed as needed but is typically set to a preset temperature. Usually, the shower mixing valve is found in the wall just beyond the showerhead.
