Swamp coolers need a constant flow of water to work.
Hooking into a home 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.
Here are a few ways it can be done.
1…Use a Swamp Cooler Install Kit.
A install kit uses a screw on attachment that can go to any standard water faucet.
This is the easiest method for most since there is no need to tie into a water pipe.
Some dont like this method as it can be less permanent than going straght into a pipe.
If you have limited experience with pluming and need a quick easy to use option than this is a good way to go.

2…Use a Saddle Valve and Fitting
Small valves can be placed on lines made of copper and when tighten which puncture through the line and allows water to come out the valve.
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.

3…Use a PVC Tee with a Threaded Tie In.
PVC water lines can be cut and a Tee placed into it with a fitting for a swamp cooler.
PVC pipe is glued together and cut with a hacksaw or PVC cutter.
This method often requires some digging as to find the water pipe and clear space to cut into it.
Hooking a water line to a evaporative cooler is not a difficult job but be sure to call a professional if in doubt.
The easiest mthod would be option #1 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.
