Whenever you step into the shower, you expect a mild water temperature. It should be neither too scalding nor too freezing. However, you may be startled when the shower suddenly provides no hot water. No matter how many adjustments you make, the water feels cold and uncomfortable.
When you have no hot water in the shower, check whether this issue affects the entire household. Turn on the hot water for every faucet to see if it works as intended. Do these taps only provide cold water? If so, the issue is likely your water heater. If every faucet except the shower produces hot water, the problem is the shower itself.
Losing the hot water in your shower can be a considerable inconvenience. It is particularly troublesome during the winter season, so you want to restore the temperature as soon as possible. Contact a plumber for assistance. This professional will be able to solve your hot water issue and get your shower running again.
Let’s learn why your shower water is cold and freezing.
1. Water Heater
A problem with the water heater is a common cause of cold shower water. Start by checking if the temperature on your water heater has the proper settings. The fix could be as simple as making minor adjustments. If your water heater is electric, ensure everything works correctly. When the electric unit burns out, the water may only retain heat for a short time. Alternatively, you may have a gas unit for your water heater. If so, the pilot light may have gone out.
In addition, the water heater may be an older model. Check the cold-water supply dip tube. If this component has deteriorated, the water may never reach the heater. Instead, it gets sent directly into the pipes. Check your faucets to determine whether the dip tube is your issue. If you see any bits of plastic caught in the filters, the line may have begun to disintegrate. If the hot water tank is not working, call a plumbing service for an inspection.
2. Hot water usage
When diagnosing a lack of hot water in the shower, usage is something to consider. Are others in the household showering before you do? Likewise, have you recently run the washing machine or dishwasher? You may have encountered a scenario where your household’s water usage exceeds the finite supply.
Some hot water heaters also have specific on-and-off cycles. The water won’t get hot if your shower happens during an off-cycle time. Wait a minimum of thirty minutes after a shower or running an appliance. That way, you can allow your water heater to restore to standard levels. If it is an ongoing problem, consider upgrading to a larger water heater tank.
3. Shower valve
If the shower is the only place where you are not getting hot water, there is a problem with the shower plumbing. Start with checking the shower valve. This component allows hot and cold water to mix. It also regulates the temperature of the water that comes from the shower head.
The valve will no longer work properly if the O-ring or washers have worn out. Replacing these parts is something avid DIYers can do themselves. However, the process can be complicated since the plumbing is inside your walls. It’s best to call a Whitby plumber to repair the shower valve instead.
4. Anti-scald device
Most shower heads have something called an anti-scald device. This safety feature limits how far the shower handle can turn in the hot water direction. If you get hot water from the other faucets except for the shower, your anti-scald device may be defective.
It is easy to check if this device is the issue. First, remove the handle of the faucet. If you see a plastic component sitting right under the faucet head, that is most likely the anti-scald device. A visual inspection should be sufficient to ascertain whether the device is in good shape. If the device is damaged, you will need to replace it.
If the anti-scald device is not faulty, it may have incorrect settings. Pull out the device slightly, turn it to the right, and push it back into place. When you test the water, you may notice it getting warmer than before.
If you live in an older house, there may be corrosion in your plumbing system. Rusty pipes often cause obstructions, preventing the flow of hot water. It’s unlikely to be a problem in a newer home using copper or plastic piping. However, corroded plumbing is more prevalent in aging properties.
You should call a plumber to assess the severity of your corroded pipes. This professional will diagnose the situation before making recommendations. You may need to replace some piping to ensure the hot water flows smoothly throughout your home.
