If your air compressor’s pump cycles are only a few times per day, you should drain your compressor tank every other day or several times per week to prolong its operating life. How does an air drain valve work?

Where is the drain valve on an air compressor?
A condensate drain valve is a small device typically located at the bottom of a compressor's air receiver. Whether the air compressor drain valve is open or closed determines if water flows out of or remains inside the compressor tank.
Do air compressors need to be drained water?
In short, the more you use your compressor, the more moisture will build up inside it. And the more moisture, the more often you'll need to drain it. So while you may not need to drain it after every single use, it's best to drain it at least once a day.

Grip the ring on the valve with a pair of locking pliers. Turn the valve counterclockwise with the pliers. Open the valve only a little at first until the pressure lessens. Continue to open the valve more, allowing both air and condensation to release from the tank.
How often should you drain the water out of an air compressor?
It is recommended that you drain your tank daily, whether it is manually or automatically. Water build up in your tank can cause the bottom of your tank to rust forcing you to invest in a new tank.
How often should I drain my compressor?
dailyBy draining your tank completely on a daily basis, you will be actively preventing the effects of corrosion and prolonging the life of your air compressor.
Should I leave the drain valve open on my air compressor?
Drain tank of moisture after each day's use. If unit will not be used for a while, it is best to leave drain valve open until such time as it is to be used. This will allow moisture to completely drain out and help prevent corrosion on the inside of tank.
Do I have to drain my air compressor after every use?
Draining your compressor after every use is not necessary unless you use it very rarely. A good practice would be to drain the compressor tank every couple of days for daily use. This helps you remove the condensate and moisture gathered inside the tank, slowing down the corrosion process.
Is it OK to leave air in a compressor?
I always drain my compressor when finished, mainly to blow out any moisture that could have built up inside. You should vent the air through the valve on the tank itself (facing towards the ground) for at least the last 40-60 lbs of air to help blast out and remaining moisture.
Why does my air compressor have water in it?
As the compressed air cools down, it can no longer hold the same amount of water vapor, so the extra water gets forced out of the air in liquid form. By the time the air has cooled to the temperature range typical for pneumatic tools, which is about 120° F. and below, quite a bit of water has formed.
Do I have to drain my air compressor after every use?
Draining your compressor after every use is not necessary unless you use it very rarely. A good practice would be to drain the compressor tank every couple of days for daily use. This helps you remove the condensate and moisture gathered inside the tank, slowing down the corrosion process.
Why should you drain water from compressed air tanks?
A Water can freeze in cold weather and cause brake failure. Compressed air usually has some water and some compressor oil in it, which is bad for the air brake system. For example, the water can freeze in cold weather and cause brake failure.
Why you should drain your air compressor?
This is because when air is pumped into the tank, it also brings in the moisture content of the air. No matter the size of the unit, you will need to drain away the moisture lest it becomes problematic for the operation of your air compressor.
Can you leave pressure in an air compressor?
Yes, definitely drain it after each use. Need to avoid letting water pool in the tank, possibly corroding and weakening it. Release the air and open the drain valve for a while to let out any condensation.
Why Is There Water in My Air Compressor?
It’s impossible to prevent water from getting into your air compressor. This is because all air has moisture in it. Compressing air necessarily causes that water to turn from its vapor form into liquid as it condenses. When it builds up enough, it can make its way into the compressed air stream.
Can Moisture Cause Damage to the Air Compressor?
Water in your air compressor can cause damage to the system in several different ways. These include corrosion, instrument malfunction, water hammer, and ice formation in cold temperatures. These can all be avoided with proper maintenance and prevention.
How to Keep Water Out of the Air Compressor?
Do this by using a dryer to remove the water droplets inside the tank. However, when you use this, it won’t remove the water vapor that’s produced when you’re using the air compressor itself.
What happens if you don't drain your air compressor?

What is the valve on an air compressor called?
All air compressors feature a valve that you can use to drain your air compressor. It’s called a drain valve. The valve comes in different sizes and shapes depending on your air compressor model.
Why drain air compressor?
Why Should You Drain Your Air Compressor 1 Water can corrode. Over time, there will be a development of rust inside the tank, resulting in damaging your air compressor’s structural integrity. Worst case scenario, your air compressor will explode. 2 The remaining water inside the tank can get to your air tools resulting in permanently damaging them. When the air tools draw air from the tank, water can accompany the water and get inside the instruments. 3 The water will block the space inside the tank where the air is supposed to be. This means a smaller area for the air and reduced efficiency of your air compressor. Also, the pressure gauge won’t be able to give the proper readings if there’s water inside the tank. 4 Sucked particles together with water can interfere with airflow. It will also get in the airways of your air tools and permanently damage their efficiency.
Why are drain valves located below the tank?
It’s simple science. If you want something to fall out of a container, gravity must do its magic. That’s why drain valves are located below to empty the tank quickly.
How did water get inside a tank?
So, how did the water get inside? When we fill the tank with air from the atmosphere, it contains vapor. Compressing the air inside the tank results in producing water droplets.
Do air compressor valves look like valves?
The valve may be different in different model air compressors. Some look like an actual valve, and some don’t. If you can’t figure it out, check the manual for help.
