How to Hookup or Repair a Swamp Cooler Water Line

The swamp coolers are usually applicable in places with very low moisture. They are also known as evaporative coolers, and they have that name because they put some moisture to cool down hot places, and they are found in many places, including the factories. Also, they prevent the hot places from any damage or from blowing out. Despite being effective, sometimes they may become faulty and will require some fixation.

Air conditioners operate by drawing external air via water-soaked matting. For a percent of the expense of typical air conditioners, this dissipation cools down to a safer temperature. These evaporation coolers have a tank at the base from which water is pushed to the surface and drained via the matting to keep the carpets moist. The tank is kept full of water by a floater in the tank.

Sometimes, your swamp cooler water line may fail to function as usual and require some replacement or hooking up. The swamp cooler water lines are essential, especially if you use them in low moisture places. To repair or hook up a faulty swamp cooler water line, follow the steps below.

Step 1: Collect all the materials necessary

There are several materials you may need to carry out the process successfully. The equipment includes the following;

  1. A new swamp cooler water line requires two pairs of pliers or wrenches.
  2. screwdriver
  3. lubricant that penetrates
  4. Float valve replacement

Ensure you have all the equipment. If not, consider buying the tools from any nearby repair shop, or you can borrow from your friend. If there is an issue, seek help immediately from an expert to help you solve the issue.

Step 2: Find the position of the water supply source and disconnect or turn it off

Locate a water supply as near to the swamp cooler as feasible. External nozzles can be converted with adapters so that a pipe can be attached to one edge and a connection to the freezer can be attached to another. When it’s possible, this arrangement is the most straightforward way to connect the cooler. If you can’t find one, look for a neighboring cool plumbing system.

While locating the water supply source, check the pipes that allow water to flow to their destination are in good condition. Also, ensure the cooler is empty after disconnecting it from the water supply source.

Finally, carry the manufacturer’s guide along for more information or if there is an issue requiring research. Also, seek help from an expert if the water supply source is faulty.

Step 3: Connect the ice maker to the nozzle into the waterline

To plug into a drainpipe or water line, apply a saddle faucet similar to the one used to attach drip trays or ice makers on the fridge. These faucets are made to be clipped to the water supply route.

Then screw the valve using the screwdriver down till the water line is pierced by a little blade within. Unbolt the valve just enough to allow the water to escape, then turn it off until the attachment is firm.

Step 4: Connect both the swamp cooler to the edge of the plastic water tubing

Connect the rubber or plastic water piping to the swamp cooler’s tip. For this attachment, there must be a matching along the lower border. If the company’s guidelines are accessible for this hookup, please refer to them. A compression coupler is important, and this piping.

 A bolt cover must be put onto the piping, followed by a little metal frame. Plug the tubing’s other side into the swamp cooler’s connection. Adjust the connection with a wrench until it is firm.

Step 5: Extend the tubing to the wall

If you need to extend the piping for more than just a few inches, attach it to the building’s wall using nails that you put in with a hammer. Take care not to harm the tube by driving these pins too deeply. Take the route that conceals the piping to the greatest extent possible.

Step 6: Attach the other side of the water piping to the valve on the outside tap or the saddle nozzle

Based on whatever water supply source you’re utilizing, attach the other side of the water piping to the valve on the outside tap or the saddle nozzle. Both types of connections will need the same processes as the swamp cooler hookup. Inspect for cracks that result in leaks by turning on the tap. Adjust any leaking connection till it no longer spills.

Ensure the cover in the swamp cooler is set to hold the leak from pouring in a foot or so underneath the reservoir’s bottom. It will allow it to add hot water after the motor has withdrawn some liquid, allowing the freezer to continue even without moisture overfilling when it is turned off.

Process 3: Place the Lateral swamp cooler Fins in Place

Insert one of the swamp cooler fins included with the device into the underside of the cooler’s rail and release it till the other end of the fin meets the glass panel. Cover the sides of the fin using some materials that are; silicone caulk and fasten it with two square 1/4-inch bolts.

Try the process again with the swamp cooler fin on the opposite end. Lock the opening and use sealant to fill the space between the opening and the swamp cooler’s lid.

Process 4: Join the Waters, Connect the device and run a check on it

According to your preference, attach the water supply source, then switch on the water and wait for the reservoir to fill. So when the tank is complete, a floating device must shut off the water flow. Turn the unit on and check it’s working properly after plugging it into a 120 voltage GFCI socket.
