An airlock in your water system is a bubble of air trapped within the pipes, preventing the normal flow of water. This blockage can cause a variety of problems, from reduced water pressure to a complete lack of water from a tap or fixture.
Understanding Airlocks
- How they form: Airlocks typically develop when air enters the plumbing system. This can happen during repairs, when the system is drained and refilled, or if there's a sudden change in water pressure.
- Effects: The trapped air bubble creates a barrier, hindering the smooth passage of water. This results in:
- Reduced water pressure at affected outlets.
- Spluttering or sputtering taps.
- Complete blockage of water flow.
- Unusual noises in the pipes.
Clearing an Airlock
There are several methods to clear an airlock, one of which involves using a hosepipe.
Using a Hosepipe
The reference provides the following method:
- Connect a hosepipe: Attach one end of a hosepipe to the cold tap and the other end to the hot tap of the same sink.
- Turn on the cold tap: Turn on the cold water tap so that water flows through the hosepipe and into the hot tap. This reversed flow of cold water into the hot water pipe should force the airlock out of the system.
This process often resolves airlocks by creating a strong flow of water that pushes the air bubble through the pipes.
Other methods
While the reference only detailed the hosepipe method, other common techniques can help resolve airlocks:
- Running taps: Sometimes, simply running all the taps in the house for a few minutes can dislodge an airlock.
- Bleeding the system: If your heating system is affected, bleeding the radiators can release trapped air.
- Professional help: If the problem persists, a professional plumber can use specialized tools and techniques to identify and clear the airlock.
Summary Table
| Problem | Possible Cause | Solution |
|---|---|---|
| Reduced Flow | Airlock | Reverse water flow using a hosepipe as described. |
| Sputtering taps | Airlock | Allow water to run for a few minutes. Consider a hosepipe method. |
| No water flow | Severe airlock or other plumbing issue | Use hosepipe method. If that does not work, seek professional help. |
Airlocks can be an annoyance, but understanding how to clear them can help you restore your water flow quickly and efficiently. Remember if you are unsure seek professional assistance.
