How to Make a Rain Gauge From Plumbing Parts

Understanding the exact amount of rainfall helps you know when to water the garden.

Successfully growing flowers and vegetables outdoors may prove challenging because Mother Nature is inconsistent. Knowing the exact amount of recent rainfall allows you to adjust your watering schedule to ensure the plants get exactly what they need. A rain gauge -- built with a few common plumbing parts -- is a simple device that collects rainwater for measurement.

Things You'll Need

• Measuring tape
• 4-inch PVC pipe
• Miter saw
• Permanent marker
• PVC pipe cap
• PVC glue

Instructions

1. Measure and mark the 4-inch PVC pipe at the 10 inch mark. Cut the pipe along this line with a miter saw.

2. Hold the measuring tape on the inside of the pipe and mark the pipe every half inch with a permanent marker. These markings should start at one end; use shorter lines for the half inch intervals and longer lines for the one inch intervals.

3. Apply PVC glue to the inside of the PVC cap. Push the cap onto the end of the pipe where the markings start.

4. Place the rain gauge in your garden in a location that is unobstructed from above. Check and record the amount of water in the gauge on a daily basis.

Tips & Warnings

• Usually, a lawn or garden demands approximately one inch of rain per week. This varies according to the local climate and specific plants needs. Learn your garden by watching the plants closely. A plant's leaves begin to sag when it gets thirsty.

• Over-watering your garden and lawn can lead to plant diseases; achieving the right balance comes with experience and practice.
