How To Drain Water from An Evaporative Cooler?

Your swamp cooler performed this late spring admirably, and you expect it to last for a long time. When you aren’t using the swamp cooler, you may think about how to empty all water. Temperature fluctuations and accumulated water can destroy the swamp cooler. But the evaporative cooler can be run 24/7 if maintained properly. We did all the research for you, and here’s the result. To empty the water from the sump/evaporative cooler, use the following methods:

  1. Turn off the power and the water supply before opening the overflow/drain plug at the bottom of the storage pan.
  2. Grasp the screw-nut from underneath with a pair of pliers.
  3. Twist the screw in the opposite direction with your other hand.

Evaporative Cooler

Why draining the cooler is essential?

Evaporative coolers, also known as swamp coolers, cool the air by passing it through a “water cushion,” which causes evaporation. If you don’t use a cooler, the collected water can become stale, resulting in an unfavorable, never-ending form through the framework. If you live in a cold climate, freezing temperatures can cause water to freeze and damage rotary components. The circulation pump motor gets overheated when it operates at maximum torque. When the water is frozen, the motor is overloading its capacity and is susceptible to burning out, possibly resulting in the melting of motor winding.

What is the best way to empty the cooler?

To avoid the previously mentioned issues, you must dispose of the cooler water when not in use. To accomplish this, use the following methods:

Turn off the power

  • Turn off the device.
  • In the electric breaker box, turn off the appropriate breaker.
  • The device usually has plugs and sockets.
  • Cut off the water supply from that point forward.

Empty the Reservoir Tank’s Water

After you’ve turned off both the water and the power, it’s time to empty the water from the supply container. This will necessitate the use of several movable wrenches or forceps.

  • Locate the reservoir plug/flood tube inside the repository skillet.
  • Locate the screw nut connected to that fitting beneath the dish, near the bottom of the fitting.
  • Secure the wrench to the screw-nut in a safe manner.
  • Wrap the reservoir plug around the screw nut at the top.
  • Fold a couple of elastic groups over the screw before turning it. You would not use a wrench on the screw because it would destroy the strings (sections) and cause spills.
  • Turning the screw-nut to the right and then to the left loosens it.
  • Turn the screw course around. Once the plug is removed, the water should drain away.
  • This wrench is flexible and lockable, making it ideal for anyone who needs a firm grip without much strength.
  • After cutting off the supply, you’ll need to empty the water from the cooler’s line.

What Is the Best Way to Drain the Swamp Cooler Line?

To clean out the swamp cooler line, separate the end of the hose at the absolute bottom, which is usually at or near the water supply itself.

If your cooler has an outside hose, unscrew it at the spigot and allow the water reservoir to drain; if your cooler has a float valve, set it to the open position and will enable the water to drain.

Is it normal for water to leak from the swamp cooler?

Although the example cooler should not spill, it may give the impression that water is leaking from it, which could be a regular occurrence or a significant change.

A Purge Pump in your water cooler

If you have a purge pump, ensure the water in the line is changed regularly. “Remove” the old water with a flood/reservoir plug. This can make it appear as if the cooler is leaking.

The float valve on the water cooler may be too high.

If the float valve is too high, excessive water can enter the supply and cooler line through the plug. This indicates that the cooler is not operating correctly; in any case, the float valve should be replaced. To do this, twist the float valve wire arm and lower the water level to 1/4 to 1/2 inch beneath the valve attachment’s highest point.

Drain water from the evaporative cooler!

You now have a firm grasp on draining the sump/evaporative cooler. If the device is mounted on a window, you can usually do it alone; if it is mounted on a rooftop, you may need extra or expert assistance.

To avoid harm while overwintering, consistently reservoir the tank and water line. There should be no holes in your water cooler. In this case, the unit may have a purge pump, or the float valve may be improperly tuned. If properly maintained, the swamp cooler should last a long time.
