Imagine it’s a cold winter morning, and you’re looking forward to a warm shower before starting the day. But as you turn on the taps, the water splutters and dribbles out, far from the steady stream you expected. This frustrating scenario can often be attributed to air locks in your water tank system. These air blockages can cause irregular water flow and reduced pressure that disrupt daily household activities. But what exactly causes these air locks, and more importantly, how can you resolve them?
Understanding Air Locks in Water Systems
An air lock is a blockage in your water pipe system, caused by trapped air. This air prevents water from flowing through the pipes correctly, leading to weak water output or no water at all from taps. Identifying and resolving air locks is crucial because they not only inconvenience you but can also strain your water system, leading to further damage if left unaddressed.
Common Causes of Air Locks
Air can enter your water system through several routes, typically during maintenance, incorrect installation, or when refilling the system after draining it. Common causes include:
- Incomplete Draining: If the water system isn't fully drained during maintenance, air can get trapped.
- Leaks: Damaged or loose fittings can allow air into the system.
- Improper Installation of Water Tanks or Pipes: Incorrect slopes or orientations of piping can trap air.
Symptoms of an Air Lock
The signs of an air lock include:
- Inconsistent Water Flow: The taps splutter or fail to deliver a consistent flow.
- No Water: In severe cases, taps might stop releasing water altogether.
- Unusual Noises: Whistling or banging sounds from the pipes can indicate trapped air.
DIY Tips for Fixing Air Locks
Here are a few ways you can attempt to clear an air lock:
1. Turn on the Hot and Cold Taps Simultaneously: If the air lock is minor, operating all taps may help force the air out with water pressure.
2. Use a Hose to Connect Taps: Attach a hose between the hot and cold taps on a sink, turning both taps on. The pressure from the main water supply can help push the trapped air out.
3. Drain the System: For gravity-fed systems, draining the water tank and pipes can flush out the air. Turn off the main water supply, open the lowest taps in the property, and allow all water to run out. Turning the water supply back on can push the remaining air out.
When to Call a Professional
If DIY methods don't resolve the air lock, or if you’re hesitant about attempting them, it's time to call in a professional. Here are instances when expert intervention is advisable:
- Persistent Symptoms: If symptoms persist despite attempts to clear the air lock.
- Complex Systems: Homes with multiple water tanks or complex plumbing might require a professional to assess and correct the issue effectively.
- Frequent Recurrences: If air locks occur frequently, there might be underlying issues such as improper pipe installation or hidden leaks.
Long-Term Prevention of Air Locks
Prevention is always better than cure. To prevent air locks:
- Regular Maintenance Checks: Regularly inspect and maintain your plumbing system to ensure there are no leaks and that all connections are secure.
- Proper Installation: Ensure water tanks and piping are installed according to guidelines, which can minimise the chances of air getting trapped.
- Air Bleed Valves: Consider installing air bleed valves at strategic points in your plumbing system. These valves are designed to allow trapped air to escape automatically.
Conclusion
Dealing with air locks in your water tank system can range from being a minor annoyance to causing significant disruptions in your water supply. Recognising the signs early and understanding how to tackle them can save you time and discomfort. Try the methods suggested above for removing air locks, and remember, persistent issues should be checked by a professional to protect and maintain the integrity of your plumbing system.
For the best results and as a practical step forward, consider scheduling a routine check-up of your plumbing system. This inspection can help catch potential problems like air locks before they escalate, ensuring that your water system remains efficient and reliable.
