How To Replace The Rain Gauge Foam

If the blue measurement tube in your World’s Coolest Rain Gauge® is no longer floating properly, the foam inside the tube may have deteriorated over time. Fortunately, replacing it is quick and easy with our replacement foam kit.

Each foam kit includes:

• two replacement foam pieces (one extra)
• adhesive
• a toothpick applicator

The adhesive helps hold the foam in place and also makes insertion easier by helping the foam slide smoothly into the tube.

Step 1: Remove the Old Foam

Use a broom handle, dowel, or similar blunt object to gently push the old foam out of the blue tube.

Don’t worry if a little of the old adhesive remains inside the tube. It usually won’t affect the repair.

Step 2: Apply the Adhesive

Squeeze a small amount of adhesive around the inside bottom edge of the blue tube.

Use the included toothpick to spread the adhesive evenly around the interior surface.

You don’t need a large amount — just enough to lightly coat the inside where the foam will sit.

Step 3: Insert the New Foam

Push one piece of replacement foam into the tube until it sits evenly at the bottom.

The adhesive will help guide the foam into place while also securing it once dry.

Try to keep the foam level and flush with the bottom edge of the tube.

Step 4: Let It Dry

Allow the adhesive to dry overnight before placing the tube back into your rain gauge.

Once dry, reinstall the tube and your rain gauge should float and measure rainfall properly again.

A Few Helpful Tips

• The kit includes one extra foam insert just in case
• A broom handle works especially well for removing old foam
• If the foam feels tight going in, twist gently while pushing
• Avoid using excessive adhesive
• Make sure the tube is dry before beginning the repair

A fresh foam insert can give your rain gauge many more years of service and keep it floating properly through rainy seasons ahead.
