If your well can't get enough water supply due to drought, the pump system will suck in air as it functions. The trapped air will make its way into your piping and faucets. The problem will persist for as long as the drought continues.
Airlocks do sometimes fix themselves, but it isn't a risk worth taking. Airlocks occur when air becomes trapped in the hot water or central heating system. Vapour becomes caught in a high point of the pipework because the gas is less dense than the water in the system.
While these sounds can be scary and seem like serious issues, the cause is usually quite benign. Most often, a loud sound coming from your pipes is caused by trapped air. By turning off your main water supply and running all faucets for 10-15 minutes, you force any trapped air through your water pipes.
After you turn off your mains water system and drain excess water from your residence, turning the water back on and running your faucets and house appliances that use water can remove air bubbles from the pipes.
If you have any leaks in your pipework, air can enter the water lines through them. Any such leaks can throw your home's water supply network out of balance, causing significant water pressure problems. Also, the amount of air in your plumbing system will continue to increase, worsening the noise and water flow issues.
When turning the water back on to your house, you must be careful not to let air and water rush back into the pipes too quickly. You should turn the water back on slowly. Open one or two faucets before turning the water back on, then incrementally restore water until you see it freely flowing out of the open fixture.
Open Your Faucets and Water Connections
Open every faucet in your home with a one-half turn of the tap to drain your water with an even flow and release air from the line. Start with the taps closest to your well's main water valve and work your way throughout your home.
Air lock problems typically occur in hot water lines, as well as in heating systems that rely on hot water, such as boiler and radiator heating units.
WSSC suggests running all COLD water taps for about five minutes or until the water runs clear. Begin with the lowest faucet in your home or business and then open the other faucets one at a time, moving from your lowest floor to your highest.
This test is simple: just apply soapy water to piping or connectors where a leak is suspected. If soap bubbles form, you have found your leak.
The trapped air can cause pressure build-up, which can lead to leaks or bursts in the pipes.
Water supply issues can cause toilets to bubble if the water pressure in the pipes is too high or too low. If the water pressure is too high, it can cause the water to flow too quickly through the pipes, which can create air bubbles.
Overall, it's best that you take heed and drip your faucets when temperatures dip below freezing. A simple trickle of hot and/or cold water—both from faucets inside and outside the home—can prevent you from having to deal with a much larger issue (and bill!) in the long run.
Many people tend to think they can turn their water back on by themselves after it has been shut off. However, this is not the case. If your water has been shut off due to a late payment, you can not turn it back on by yourself legally. If you are caught doing so, there will be legal action.
Switch the spigot on by turning it counterclockwise and ensure there is a steady flow of water.
Call a Professional to Remove Air Bubbles from Water Pipes
Trapped air in water pipes has the potential to inflict lasting damage on your plumbing system.
Rapid Pressure Changes: Quickly shutting off a valve or turning off a large appliance like a washing machine can cause a pressure surge, sucking air into the pipes.
In worse cases, the air pressure can cause water to shoot from the faucets. This trapped air can even cause loud thumping sounds when the water is turned on. To remove the air as well as get rid of any noises, you should know how to bleed plumbing pipes.
A clogged aerator, damaged cartridge, loose or broken handle, or faulty internal faucet valve can be the culprit. If the lack of water is localized to a single faucet, look for visible defects, such as a damaged spigot, broken handle, or issue with parts of a faucet that can prevent water from coming out.
Air in water pipes is commonly caused by a waterlogged pressure tank.
