How to Drain Water from an Evaporative Cooler (Tested Ways)

This year, your swamp cooler has performed well, and you want it to last for years to come. You may be wondering how to drain all the water from your evaporative cooler because temperature changes or standing water can destroy it while it’s not in use. We’ve already laid the groundwork for you and have all of the answers.

To remove the water from your swamp or evaporative cooler, follow these steps: Turn off the power and the water supply, open the overflow/drain plug at the bottom of the reservoir pan with a pair of pliers while holding the screw-nut underneath. With your other hand, twist the screw in the other way.

The evaporative cooler system relies on water, and you don’t want standing water to freeze or stagnate in the system over the winter. So read on for more information on how to drain the water from your evaporative cooler in the thorough discussion below.

Why Is It Necessary To Drain The Cooler?

The evaporative cooler is also known as a “swamp” cooler, but regardless of what you call it, it works by forcing air through a pad of water to create an evaporative effect that cools the air. When your cooler isn’t in use, though, standing water can collect and cause mold and mildew to grow throughout the system. Freezing temperatures might cause water to expand and shatter the pieces of your water cooler if you reside in a cold location.

How to Drain the Cooler

To avoid the difficulties mentioned above, the most important thing you can do for your cooler removes the water when it is not in use. Follow the procedures below to accomplish this.

1.     Turn the power Off

ensure that you switch off the unit’s power.

At the unit itself – generally under the unit, there is a socket and outlet; or

Turn off the appropriate breaker at the electrical breaker box.

Turn off the water supply at this point.

ü How to Turn Off The Water To the Swamp Cooler?

o   Locate the unit’s water supply; you can find it in a variety of places. Search all of your water supply faucets for anything that looks like a secondary faucet with a small metal or plastic hose leading away if you don’t know where it is. You can find it in a variety of locations.

At the hose faucet, to be precise.

o   When you’ve found the right source, turn the lever or knob to switch off the water supply to that hose. It is a typical outside faucet water supply. You can shut off the hose-connected extra valve without disrupting the water flow to the main faucet. When the valve handle is aligned with the pipe on a ball valve, the water is turned on. To turn off the water, turn the handle until it comes to a complete stop. Typically, this is at a 90-degree angle to the pipe.

o   To remember which way to loosen or tighten screws, especially conventional water-faucet shut-off valves, recall the phrase “Righty-tighty, Lefty-loosey.”

2.     Now drain the Reservoir Tank’s Water.

It’s time to empty the water from the reservoir or holding pan now that you’ve switched off both the water and the power. You’ll need a pair of adjustable wrenches or pliers for this.

ü Inside the reservoir pan, look for the drain plug/overflow tube.

ü Locate the screw-nut connecting to that plug beneath the pan, near the bottom of the plug.

ü Securely fasten the wrench to the screw-nut.

ü Twist the drain plug at the top while holding the screw-nut in place underneath. Wrap a couple of rubber bands around the screw before rotating it for more grip. You don’t want to use a wrench on the screw since it will destroy the threads (grooves) and cause leaks. Remember that twisting the screw-nut to the right tightens it, and turning to the left loosens it. Turn the screw in the opposite direction.

The water should flow away after the drain plug has come loose. The wrench is adjustable and locks in position, making it ideal for anyone who requires a firm grip without the might of Hercules.

What Is The Best Way To Drain The Swamp Cooler Line?

Disconnect the end of the hose at the lowest position, which is usually at or near the water supply itself, to drain the swamp Cooler line. If your cooler is connected to an outdoor hose, detach it at the faucet and let the water drain. Turn the drain valve to the open position and allow the water to drain into a pail or container if you have one. The T-valve prevents unscrewing – and possibly destroying – the fittings that maintain the supply water-tight when the line needs to be drained.

Is It Necessary To Fill A Swamp Cooler With Water?

The water pump in a swamp cooler must have water in the reservoir before turning on; otherwise, the water pump would burn out. There are two sorts of coolers: portable and fixed, and if you can’t find the manufacturer’s instructions for filling the reservoir, follow these steps.

ü Evaporative/Swamp Cooler that is fixed

The water comes from a faucet that you may turn on and off manually. Before turning on the power, turn on the water and let the lines/reservoir fill. A switch on the unit turns on the water supply. Before turning on the power, turn on the water supply switch for the necessary amount of time.

ü Evaporative/Swamp Cooler that is portable.

Manually filling the water supply is required. Fill the reservoir regularly – many portable units will shut off if the water supply is depleted. A hose faucet provides the water supply. A continual water supply is typically required for these larger portable units. Connect the hose to the water supply, turn it on, and wait for the reservoir to fill before turning on the power.

Frequently asked questions

Is Water Leaking From A Swamp Cooler Normal?

Although a swamp cooler should never leak, there are a few instances where water may appear to seep from your cooler; nevertheless, these are either a standard element of operation or a simple adjustment. One, a Purge-Pump Is Installed In Your Water Cooler. If you have a purge pump, it will change the water in the reservoir regularly. The old water is drained through the overflow/drain plug. That may give the impression that the cooler is leaking.

Again, the float valve in your water cooler may be set too high. If your float valve is set too high, too much water may enter the reservoir and drain out of the overflow/drain plug. ThAT does not imply that your cooler is leaking; rather, it indicates that the float valve needs to be adjusted. Adjust the water level by bending the wire arm of the float valve to about 1/4 to 1/2 an inch below the top of the overflow/drain stopper.

What is the source of the water pouring from my evaporative cooler?

Water may be leaking from your evaporative cooler for a variety of reasons.

  •       While the cooler’s pump is working, there will be a steady water flow if your evaporative cooler has a constant bleed system.
  •       Water levels need to be reset, causing an overflow.
  •       If your evaporative cooler has a dump style drain valve, the water will be emptied every 6-12 hours (depending on the setting on your cooler) and then again when it is switched off. That ensures that the water used is of high quality.
  •       Your evaporative cooler may leak.

What are some of the advantages of using an evaporative cooler?

There are several advantages to installing evaporative conditioning in your home. These are some of them:

  •       It is a cost-effective solution. Evaporative cooling consumes less water and energy, making it less expensive to operate.
  •       Eco-friendly.
  •       Improves the quality of indoor air. Because the air is not recirculated, fresh air will be pushed through your home every few minutes.
  •       In arid climates, this is a good choice. Summers in Canberra are hot and dry, so this is ideal.
  •       Simple to keep up with. Evaporative cooling is simple to maintain because it simply requires routine maintenance.

Should I Keep My Swamp Cooler Running Throughout the Day?

Swamp coolers take in warm outdoor air and send it through drenched evaporative cooler pads to chill it down. The air that enters your home from your swamp cooler is then pleasant and chilled. So, as long as it’s hot outdoors, you might as well turn on your swamp cooler.

Because your swamp cooler requires water to function, the swamp cooler is connected to your home’s water supply valve. Water is sent through water distribution lines by the pump, located at the bottom of the cooler, to keep the evaporative pads wet.

The longer you leave the swamp cooler running, the faster it will deplete its water supply until there is none left. Your swamp cooler will stop working if the evaporative pads dry out because they don’t have access to water.

It’s not such a huge problem to have to replace the reservoir with water a few times if you’re going to be at home all day. However, if you’re spending the day at the pool or the beach with your cat or dog, it’s unlikely that your pet will be able to refill the swamp cooler on its own.

That means they only have a limited amount of time to enjoy the cool air before returning to the oppressive heat. That can be fatal for some animals. Thankfully, it doesn’t have to be an all-or-nothing situation. If you want to operate your swamp cooler for hours at a time, you have a few alternatives for reducing the amount of water it uses.

Conclusion

You should now be able to drain your swamp/evaporative cooler with ease. If the unit is mounted to a window, you can usually remove it yourself, but you may need additional assistance or a professional if your unit is on the roof.

If you’re winterizing, make sure to drain both the reservoir and the water supply pipe to avoid damage. There should be no leaks in your water cooler. If it does, it’s possible that your device has a purge pump or that your float valve is set wrongly. Your swamp cooler should provide you with cold air for years to come if you maintain it properly.
