Understanding Air Locks in Water Pipes
Before we dive into the causes and solutions, let’s clarify what an air lock is. An air lock, also known as an airbound pipe, occurs when air becomes trapped in your plumbing system, creating a blockage that prevents water from flowing freely through the pipes. This air bubble acts as a barrier, disrupting the normal water flow and causing various issues with your plumbing fixtures.
Common Causes of Air Locks in Water Pipes
Air can enter your plumbing system in several ways, leading to air locks. Here are some of the most common causes:
Draining and Refilling the System
One of the most frequent causes of air locks is when the water system is drained and then refilled. This can happen during:
- Plumbing repairs or renovations
- Seasonal draining of pipes in vacation homes
- Water main work in your neighborhood
When the system is refilled, air can become trapped in the pipes, especially in high points or bends.
Introduction of New Appliances or Fixtures
Installing new appliances or plumbing fixtures can introduce air into your system. This is particularly common with:
- Washing machines
- Dishwashers
- Water heaters
- New faucets or showerheads
Poorly Designed Plumbing Systems
In some cases, the layout of your plumbing system might be conducive to air lock formation. Issues can arise from:
- Pipes with many bends or loops
- Improperly sloped pipes
- Lack of air release valves in critical locations
Water Pressure Changes
Significant changes in water pressure can cause air to enter the system. This might occur due to:
- Municipal water supply issues
- Problems with well pumps in rural areas
- Malfunctioning pressure regulators
Leaks in the System
Small leaks in your plumbing can allow air to enter the pipes. When the water pressure drops, air can be sucked in through these tiny openings.
How to Fix an Air Lock in Your Pipes
Now that we understand what causes air locks and how to identify them, let’s explore various methods to resolve this issue. Here are several methods to fix air lock in water pipes, ranging from simple DIY solutions to more complex techniques:
The Faucet Method
This simple method often works for minor air locks:
- Turn off the main water supply.
- Open all faucets in your home, starting with the lowest point (usually in the basement) and working your way up.
- Turn the main water supply back on.
- Close the faucets in reverse order, starting from the top floor.
This process allows water to push the air out of the pipes gradually.
Bleeding Radiators
If you have a hot water heating system, air locks can affect radiators:
- Locate the bleed valve on your radiator (usually at the top corner).
- Place a container under the valve to catch any water.
- Use a radiator key or flathead screwdriver to open the valve slightly.
- You’ll hear a hissing sound as air escapes.
- Close the valve when water starts to flow steadily.
The Garden Hose Technique
For stubborn air locks, especially in outdoor pipes:
- Connect a garden hose to an outdoor faucet near the affected area.
- Run the other end of the hose to a higher point, such as an upstairs window.
- Turn on the faucet and let water flow through the hose.
- The pressure created by the water column in the hose can help dislodge the airlock.
The Plunger Method
For air locks in sinks or other fixtures with accessible drains:
- Fill the sink partially with water.
- Cover the overflow hole (if present) with a wet cloth.
- Use a plunger to create suction over the drain.
- Plunge vigorously several times.
- The alternating pressure can help dislodge air bubbles.
Using an Air Release Valve
For more persistent air locks, installing an air release valve can be effective:
- Identify the highest point in your plumbing system.
- Install an automatic air release valve at this location.
- The valve will allow trapped air to escape while preventing water from leaking.
Professional Hydro-jetting
For severe or recurring air locks, consider professional hydro-jetting:
- A plumber uses high-pressure water to clear your pipes.
- This method can remove air locks along with any debris or buildup in the pipes.
When to Call a Professional
While many air lock issues can be resolved with DIY methods, some situations warrant professional attention:
- If you’ve tried multiple DIY methods without success
- When dealing with complex plumbing systems
- If you suspect the airlock is due to a more serious plumbing issue
- In cases where accessing the affected pipes is difficult or dangerous
- If you’re uncomfortable performing plumbing tasks yourself
A professional plumber in Hillsborough has the tools, expertise, and experience to diagnose and resolve stubborn air locks effectively.
