It has happened to all of us: We turn on the hot water, and water goes everywhere and the faucet makes strange sounds. Do you need a plumber that can cost hundreds of dollars?
Having some air in the hot water line is a widespread issue all around the United States. People also describe this as cloudy water or bubbles in hot water. When you open hot water, the water pressure looks higher than normal, and there are some air bubbles in the water.
When you get air in hot water lines, the result can be a surprising mess. What causes it and how can you fix it?
Air in Hot Water Line
There is some danger to your plumbing system if you have air in your water lines. Often the problem isn’t severe, but if left alone for a long time, air can help cause corrosion and rust to form in your pipes. Thankfully, the air in hot water lines is not something that is difficult to fix.
To what is happening, let’s look at what could be causing the problem and the best way to take care of it. Keep in mind, it is not uncommon for air to be present in the hot water heater every so often, the problem comes in when it is happening all the time.
Other Signs Of Air
It is not just sputtering or hissing that will alert you to the presence of air in your lines. Another common symptom will be banging or loud noises coming from your pipes. If this happens, you can be sure that air is moving through where water is supposed to be.
This noise can be annoying, and it can also damage the pipes. Don’t run the risk of having to call an expensive plumber for what could be an easy fix. If you hear what sounds like a hammering noise, it can mean that there is water getting into the air lines, which exist to help maintain proper pressure in your pipes.
What Causes Air In Hot Water Line
Corrosion In The Tank
Water heater corrosion can occur, especially if you haven’t replaced the anode rod. Magnesium anode corrosion is designed to occur faster than the metal of the tank around it, thus keeping corrosion from occurring to the lining of the hot water tank.
In addition to finding air in your line, you can tell this issue is occurring by the effect it will have on your water. If you notice a bad odor coming from the water, or if it is cloudy and contaminated, the problem may lie with the anode rod.
If you are having some air in hot water line without any other signs of corrosion, this can be caused by the reaction between the anode and your water. The anode rod create some hydrogen because of the water and this creates some bubbles in the air.
The cheapest and most effective way of dealing with both of those problem is to use a Corro-Protec powered anode rod. This can be a long-term solution to the problem or prevent it from becoming a problem in the first place. With Corro-Protect you won’t have to deal with air in hot water lines caused by corrosion in the tank.
Water Shut Off
If the water has been shut off, you can expect that air will build up. Water is often shut off due to maintenance or other concerns, such as extended vacations or business trips. As long as this is the sole cause of the problem, turning your water back on will help work the air out of the line.
However, if the problem persists, it could be caused by something more. In this case, you may need to take additional steps to fix the problem before any damage is done to your pipes. Remember, with plumbing problems the quicker you act, the cheaper the repair will usually be.
Pressure Relief Valve
If you are getting consistent air in your hot water line, you might try shutting off the water and using the pressure relief valve on the hot water heater. Opening this valve can give the air a chance to escape, thus eliminating your problem. However, this valve may be the problem.
If the valve isn’t working correctly, you could experience water heater problems. This is because the pressure in the tank won’t be at a proper level, it could be too low and thus allow air into the system. If this happens, replacing this valve can be a fast and easy fix to the problem.
It is possible that the hose and pipe connections need to be tightened. A small amount of sediment, contaminant, or even silicone can get in the connection and create a small space for air to enter. If you don’t have any leaking water, and can’t tell that there’s a problem with any of the connections make sure you go over them all.
Is the Problem Still Persisting?
Only once you have gone through all the possible problems and solutions should you consider getting a plumber. However, if none of the previous solutions work, you need to make sure that your hot water heater is functioning properly. A professional can electrically test the system for you.
While this is the most expensive fix, far more expensive than using a Corro-Protec powered anode rod, it is sometimes necessary. Don’t let a plumbing issue rest and continue to get worse, that will lead to even more expensive damages and repair in the future. Acting fast is the only way you can save money if you have to bring in a professional.
Keep Your Hot Water System Clean
Regular preventative maintenance and the installation of useful tools like a powered anode rod can keep problems from occurring not just in your hot water tank, but in your hot water system as a whole. This is always the best and cheapest way to ensure you have clean, usable water in your home.
Air in hot water lines can be an annoyance, or it can be a serious problem. The reality is until you investigate and attempt to solve the problem you won’t know what is causing it.
