To help get all the air out of your pipes, you want to turn on every faucet in your home or building (after you've shut off the water valve). Don't turn the faucets on at full force, just enough to let the air escape.
An airlock in the pipes will eventually result in no water at all if it isn't taken care of. Even worse, it can cause blockages, overflows and other serious problems. Airlocks do sometimes fix themselves, but it isn't a risk worth taking.
The main cause of air in the water lines is water system maintenance. Cutting off the water supply for a period of time can allow air to enter the system.
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.
Noisy pipes: Loud banging, hammering, or gurgling noises coming from your pipes can indicate the presence of air bubbles. Sputtering faucets: If your faucets are sputtering or spitting water when turned on, this is a clear sign that air is trapped in your plumbing system.
If your toilet making foghorn noise after flushing, it's likely because it has a metal ballcock (don't laugh) fill valve. The washer inside the assembly may be loose or worn.
Be sure to also flush any water out of your toilets. Turn the main water supply back on. With the faucets still set in the open position, turn the water supply back on at the main valve. Let the water run for approximately 10-15 minutes, or until you don't hear any more air sputters.
Why Do Airlocks Occur? Airlocks occur when bubbles in the pipeline gather at a high point in the system. If the water velocity is not greater than the rising velocity of the air bubbles, the air will remain in the pipe and cause a restriction.

To reduce the pressure in a pipe in the long run (without installing a pressure relief system), you need to reduce the ration of fluid to pipe at any given moment. That means, 1. you actually reduce the amount of fluid going into the system, or 2. you increase the pipe size of the system.

Air in water pipes will sound like a hiss or pop. Alternatively, the trapped air can cause loud gurgling and prolonged vibrating noises.
Greater activity of the heated molecules increases the spacing between neighboring molecules and thus reduces air density. The decreasing air density then lowers the pressure exerted by the air. Warm air is thus lighter (less dense) than cold air and consequently exerts less pressure.
A hard turn 90 degree elbow equals 17 feet of straight pipe. Two hard turn 90 degree elbows as displayed in Figure 2 equaled the pressure drop of 52 feet of straight pipe! Some of the air entering a PVC pipe needs to make a 90 degree turn to enter the pipe.
Most times, a surprise spitting faucet is the result of a pressure change, which most commonly means there's air trapped somewhere in your plumbing. Aside from spitting, you may also hear tapping or banging inside the walls when your water is in use.
This is caused by excessive water velocity and air in the pipes. When you shut water off, you put a sudden stop to the movement of water through your pipes. This causes a ricochet effect where the water actually slams back and forth through your pipes until the water's energy is dispersed.
Do flow restrictors reduce water pressure? No, flow restrictors do not change pressure, but they do take pressure into account. Flow rate is dependent on three factors: the size of the outlet, the upstream pressure, and the downstream pressure.
As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. This is the reason water pressure increases with depth. The pressure depends only upon the depth, and is the same anywhere at a given depth and in every direction.
Do SharkBite Max fittings restrict water flow? No. The newly designed SharkBite Max allows for full flow of water.
