Swamp Cooler Float Valve

  
  
  

swamp cooler float valveLas Vegas water and swamp coolers often don’t get along very well. If you look inside a swamp cooler, you will see plenty of mineral deposits on virtually every surface that has come into contact with water. Take a look at the float valve. This is where the water enters the swamp cooler. This part usually gets covered with deposits. You can clean it off or replace it if it bothers you. Occasionally, the float will break and you will need to replace it.

Follow the water supply line to the cooler. With the water off, you can cut the line or unscrew the nut that holds the line to the float. The float valve is inside the swamp cooler. It has a plastic float attached to a rod. When the water is low in the reservoir, the float drops and allows water to enter and fill the reservoir. When the reservoir is full the float rises and the water shuts off.

The float valve is held on by a bracket or a hole in the side of the cooler. Remove the nut that holds the float on. The float valve will pull right out. You can install a washer on the new float and push it into the hole or bracket provided for it and then tighten the nut to hold it. Then reconnect the water supply to it.

You will need to adjust the height at which the float valve shuts off the water from entering the reservoir. You can simply bend the rod up or down to accomplish this. Most manufacturers suggest having 2 ½” -3” of water in the reservoir.
