The Introduction: Getting To Know the Basics
As modern humans, we’ve become accustomed to having water available with a twist of a knob, but how does water get to our homes in the first place? Water is often stored in large tanks that sit on top of towers, and these tanks are filled by water that comes from various sources like wells, rivers, and reservoirs. From these tanks, water is transported to our homes through water pipes.
However, have you ever wondered how air gets into these water pipes? In this article, we will explore the different ways air can infiltrate the water pipes in your home, the advantages and disadvantages of having air in your water pipes, and what you can do about it. Read on to find out more!
How Does Air Get into Water Pipes?
There are various ways air enters water pipes, some of which are preventable, while others are not. The following are the most common causes of air infiltration into water pipes:
1. Water Line Breaks:
Water line breaks can cause the water level in the pipes to drop, which creates a vacuum that draws air into the pipes. This can happen when there is a major water main break in your area, or when there is a break in the plumbing system of your home.
2. Faulty Valves:
Valves are installed in water pipes to control the flow of water. If a valve is faulty or damaged, it can create a low-pressure zone that draws air into the pipes.
3. Water Hammer:
Water hammer is a phenomenon that occurs when the flow of water in a pipe is abruptly stopped. This can happen when a faucet is closed too quickly or if a valve is shut off too abruptly. When this happens, the pressure wave created can cause air to enter the pipes.
4. Heating and Cooling Cycles:
When water is heated or cooled, it expands or contracts, causing fluctuations in pressure. These fluctuations can create a vacuum that draws air into the pipes. This is often seen in hot water heaters that do not have an expansion tank.
5. Servicing Water Pumps:
When water pumps are serviced, air can enter the pipes if they are not primed correctly afterward. This can cause air to be introduced into the water system.
6. Drainage:
Water pipes that are not used frequently can dry out, causing the seals around pipes and valves to shrink and crack. This can create an entry point for air into the pipes.
The Advantages and Disadvantages of Having Air in Water Pipes
Now that we know how air can get into water pipes, let’s explore the advantages and disadvantages of having air in the water system of your home.
Advantages:
Improved Water Quality: A small amount of air in the water pipes can help to aerate the water, which can improve its quality by removing any unpleasant odor or taste.
No Water Hammer: Air can act as a cushion in the pipes, preventing water hammer and pipe damage.
Reduced Risk of Water Hammer Injuries: Water hammer can cause sudden pressure spikes that can be dangerous, especially for young children and the elderly. Having air in the pipes can reduce this risk of injury.
Disadvantages:
Reduced Water Pressure: Air in the pipes can cause a decrease in water pressure, which can be annoying when you’re trying to take a shower or wash dishes.
Water Leaks: Air can cause water leaks by pushing water out of the pipes or by causing them to burst.
The Table: A Comprehensive Guide on How Air Gets into Water Pipes
| Cause | Description |
|---|---|
| Water Line Breaks | Low water levels in pipes create a vacuum that draws air into the pipes during a break in the plumbing or major water main break. |
| Faulty Valves | Malfunctioning valves create low-pressure areas that draw air into pipes. |
| Water Hammer | When water flow abruptly stops, a pressure wave is created that draws air into the pipes. |
| Heating and Cooling Cycles | Water expanding or contracting due to temperature fluctuations can cause pressure changes that draw air into the pipes. |
| Servicing Water Pumps | Improper priming of water pumps after servicing can cause air to enter the pipes. |
| Drainage | Dry pipes can cause shrinking and cracking of seals around pipes and valves, creating an entry point for air. |
FAQs: Answers to Your Most Common Questions
1. Does air in water pipes affect water quality?
Yes, a small amount of air in the water pipes can improve water quality by removing any unpleasant odor or taste.
2. Can air in water pipes cause water leaks?
Yes, air can cause water leaks by pushing water out of the pipes or causing them to burst.
3. What causes water hammer?
Water hammer is caused when water flow is abruptly stopped, creating a pressure wave that can cause damage to pipes and appliances.
4. Can air in water pipes cause low water pressure?
Yes, air in water pipes can cause a reduction in water pressure.
5. How do you prevent air from getting into water pipes?
You can prevent air from entering water pipes by ensuring that all valves are working correctly, avoiding abrupt changes in water flow, and maintaining your plumbing system regularly.
6. What are the signs of air in your water pipes?
The most common signs of air in water pipes are spitting faucets, sputtering showerheads, and loss of water pressure.
7. How do you get rid of air in water pipes?
You can get rid of air in water pipes by turning off the water supply and opening all the faucets in your home. This allows the air to escape from the pipes.
8. Can air in water pipes cause damage to appliances?
Yes, air in water pipes can cause damage to appliances by creating pressure spikes that can cause them to malfunction.
9. How does air in water pipes affect hot water?
Air in hot water pipes can cause fluctuations in water temperature, which can be annoying when you’re trying to take a shower or bath.
10. Can air in water pipes cause plumbing noise?
Yes, air in water pipes can create plumbing noise, especially when the water is turned off abruptly.
11. What is a water hammer arrestor?
A water hammer arrestor is a device that prevents water hammer by absorbing the shock wave created when water flow is abruptly stopped.
12. Can air in water pipes cause illness?
No, air in water pipes does not cause illness. However, it can affect water quality and may cause damage to pipes and appliances.
13. How do you know if you have air in your water pipes?
The most common signs of air in water pipes are spitting faucets, sputtering showerheads, and loss of water pressure.
