Connecting a water line to a swamp cooler is an easy job that almost anyone can do.

There are several ways to tap into an outside faucet, from tapping not the water line to different style attachments.

One way to keep it simple is to buy an Evaporative Cooler Water Hook-Up Kit.

They work by screwing on to the existing faucet and adding a second faucet for a hose, and a side mount for the swamp cooler line to connect.

How To connect a Swamp cooler Water Line to an Outside Faucet

  1. Buy a Faucet Water Hook-Up Kit.
  2. Connect it to the outside faucet.
  3. Connect the swamp cooler water line.
  4. Turn on the Faucet and Hook-Up Kit valve.

After connecting the add-on faucet, there will be two types of water lines that can be run, plastic and copper.

Copper will last much longer than a plastic line but is much harder to run. Mainly since it is much stiffer and harder to bend, this makes it more difficult to work with.

A plastic water line is much easier to install since it can be easily bent to follow the contours of a home or any building.

Plastic water lines usually last only 4-5 years, although this can depend on the direct amount of sunlight they receive.

Connecting the water line to the swamp cooler is done directly to the float, which has a switch and shuts off the water supply when the preset level is reached.
