Removing Air From Water Pipes
How can you tell if water pipes in your house are air-blocked? When you turn on the water in a faucet, the flow of water may be hampered, which is a sign that there is air in the water pipe. The water may come out in spurts, it may make all sorts of noises, and takes some time to flow out.
There is a very simple way to solve the problem. Check that the main water supply in your house has been turned on and then turn on every faucet in your house. Flush the toilets, place a cup on the water dispenser of your refrigerator, or on any other plumbing fixture in your house which has a water connection.
Turn on all the hot and cold water taps. Don’t forget the shower baths, the washing machine and the dishwasher in the kitchen. The water will flow out for a very short while. Within a minute, the noises in the faucets will cease and water will begin to flow naturally. Go up to the uppermost floor and begin to turn off the water connections that you had turned on. In this way, work your way down to the water faucet of the lower-most floor.
The procedure is simple, but you need to be patient and turn on all the faucets and then systematically turn everything off once the noise stops. If you have any questions or concerns about the procedure, it is always a good idea to consult professional plumbers.
