Did You Know? Tap Water Is Hot! Here’s Why…
What To Know
- In this blog post, we’ll explore the reasons behind why tap water can get hot and provide solutions to keep it at a comfortable temperature.
- A cross-connection occurs when the hot and cold water lines are connected incorrectly, allowing hot water to flow into the cold water line.
- If a geothermal water source is used to supply a home, the tap water may be hot, especially during the summer months.
Tap water is an essential part of our daily lives. We use it for drinking, cooking, bathing, and cleaning. But have you ever wondered why sometimes your tap water comes out hot? In this blog post, we’ll explore the reasons behind why tap water can get hot and provide solutions to keep it at a comfortable temperature.
Reasons for Hot Tap Water
1. Water Heater Temperature
The most common reason for hot tap water is a high water heater temperature. Water heaters are typically set to 120-140°F (49-60°C) to prevent the growth of bacteria like Legionella. However, if the water heater is set too high, it can cause the tap water to come out scalding hot.
2. Cross-Connection
A cross-connection occurs when the hot and cold water lines are connected incorrectly, allowing hot water to flow into the cold water line. This can happen during plumbing repairs or renovations.
3. Backflow
Backflow is the reverse flow of water from a higher pressure system to a lower pressure system. This can occur due to a faulty pressure-reducing valve (PRV) or a problem with the main water supply. Backflow can cause hot water to flow into the cold water line.
4. Solar Thermal Systems
Solar thermal systems use sunlight to heat water. If these systems are not properly installed or maintained, they can cause the tap water to become excessively hot.
5. Geothermal Water
Geothermal water is naturally hot water that comes from underground. If a geothermal water source is used to supply a home, the tap water may be hot, especially during the summer months.
6. Faulty Faucets
In some cases, a faulty faucet can cause hot water to mix with cold water, resulting in scalding tap water. This can be due to a worn-out washer or a loose handle.
7. Demand for Hot Water
During peak hours, such as when everyone in the household is getting ready for work or school, the demand for hot water can increase. This can cause the water heater to work harder and produce hotter water.
Solutions to Keep Tap Water Cool
1. Adjust Water Heater Temperature
The first step to keeping tap water cool is to adjust the temperature of your water heater. The recommended temperature is 120-140°F (49-60°C).
2. Check for Cross-Connections
If you suspect a cross-connection, contact a licensed plumber to inspect and correct the issue.
3. Install a Backflow Preventer
A backflow preventer is a device that prevents water from flowing backward into the cold water line. This can help prevent hot water from entering the cold water line.
4. Maintain Solar Thermal Systems
Regularly inspect and maintain your solar thermal system to ensure it’s working properly and not causing the tap water to become too hot.
5. Use Geothermal Water Wisely
If you have a geothermal water source, use it wisely during the summer months to avoid excessive tap water temperatures.
6. Repair Faulty Faucets
If you suspect a faulty faucet, replace the worn-out washer or tighten the loose handle to prevent hot water from mixing with cold water.
7. Reduce Hot Water Demand
During peak hours, try to reduce the demand for hot water by staggering showers and using cold water for laundry.
Final Thoughts: Ensuring Safe and Comfortable Tap Water
Understanding the reasons why tap water can become hot is crucial for maintaining a safe and comfortable home environment. By implementing the solutions discussed above, you can keep your tap water at a comfortable temperature, prevent scalding, and ensure the longevity of your plumbing system.
What You Need to Know
1. What is the ideal temperature for tap water?
The ideal temperature for tap water is 120-140°F (49-60°C). This temperature is high enough to prevent the growth of bacteria but low enough to avoid scalding.
2. How can I check the temperature of my tap water?
You can use a thermometer to check the temperature of your tap water. Simply insert the thermometer into a glass of cold water and wait for the reading to stabilize.
3. What should I do if my tap water is too hot?
If your tap water is too hot, adjust the temperature of your water heater to a lower setting. If the problem persists, contact a licensed plumber to inspect your plumbing system.
4. Can I use cold water to cool down hot tap water?
Yes, you can run cold water from another faucet to cool down hot tap water. However, this can waste water and increase your utility bills.
5. What is a pressure-reducing valve (PRV)?
A pressure-reducing valve (PRV) is a device that reduces the water pressure in a plumbing system. A faulty PRV can cause backflow and lead to hot tap water.
