Swamp coolers need a water line for a constant flow of water to operate properly.
Hooking into a water line for a swamp cooler can be done a few different ways depending on the placement of a unit and types of water pipes.
There are several ways to connect a water line to a swamp cooler with some more permanent and some more easy.
A water line will connect to a float valve which will automatically turn on and off the water in the cooler.
Below are the most common methods for connecting a water line to an evaporative cooler.
Types of Swamp Cooler Water Line Hookups
They are simple to hook up with a small line going between the faucet and the cooler water valve.
The one downside of a swivel adapter is it uses the entire faucet which may be needed for other things such as watering plants.
Swivel adapters are used by many as a quick way to connect water to an evaporative cooler.
This is the easiest method for most since there is no need to tie into a water pipe.
Some don’t like this method as it can be less permanent than going straight into a pipe.
If you have limited experience with plumbing and need a quick easy to use option this is a good way to go.

This is easy to do for those who have copper lines.
Often they are located at the water heater since the top cold water line going in is almost always copper.

PVC pipe is glued together and cut with a hacksaw or PVC cutter.
This method often requires some digging to find the water pipe and clear space to cut into it.
Hooking a water line to an evaporative cooler is not a difficult job but be sure to call a professional if in doubt.
The easiest method would be option #1 or #2 above since it does not require cutting into any pipe.
If a water pipe is going to be worked on, be sure to turn off the water at the Main.
