How to Hookup or Repair a Swamp Cooler Water Line
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.

    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.

    There are also install kits that use 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 plumbing and need a quick easy to use option this is a good way to go.

    Small valves can be placed on lines made of copper and when tighten 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.

    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 to find the water pipe and clear space to cut into it.

    Summary
    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.

      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.

      Thanks!
