Here are a few ways it can be done.

    An 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 don’t like this method as it can be less permanent than going straight into a pipe.

    If you have limited experience with pluming and need a quick easy to use option this is a good way to go.

      Hey Aaron –

      Great post.

      Any tips on how to winterize a swamp cooler? I have a Breezaire unit. I should drain the supply line, right? It’s connected via a saddle valve and copper line.
