The Benefits of Installing a Rain Barrel with Overflow

Are you looking for ways to save money and be more environmentally friendly? Installing a rain barrel with overflow is one of the best options. Not only will it help you save money on your water bill, but it also reduces the amount of runoff that can damage waterways. In this blog post, we’ll discuss what a rain barrel with overflow is, its benefits, how to install it, tools required, setting up an overflow system, checking for leaks after installation, maintaining and cleaning the rain barrels with overflow, cost savings from using a rain barrel with overflow, and creative ways to use rainwater collected in your barrels.

What Is a Rain Barrel With Overflow?

A rain barrel with overflow is a container designed to collect and store excess rainfall for later use. It typically consists of a large plastic or metal tank placed beneath a downspout where roof runoff collects and fills the tank with fresh water. A diverter valve installed near the top of the tank redirects excess water away from the tank into a second pipe leading to either another collection vessel or the storm drain. The purpose of the overflow system is to prevent the tank from overflowing when too much water enters at once.

Benefits of Installing a Rain Barrel With Overflow

Installing a rain barrel with overflow provides numerous benefits. Firstly, it helps conserve water as it captures and stores any excess rainfall which can then be used later during dry periods. Secondly, it can help reduce your water bill by providing an alternative source of water for household tasks like gardening, car washing, and even indoor uses such as laundry and flushing toilets. Lastly, installing a rain barrel with overflow helps protect nearby bodies of water from runoff pollution. By preventing excess water from entering streams, rivers, and other waterways, it helps keep them clean and healthy.

How to Install a Rain Barrel With Overflow

When installing a rain barrel with overflow, there are several steps you must take:
1. Measure the area around your downspout and determine the size of your rain barrel (typically 55-100 gallons).
2. Gather all the necessary tools and materials including PVC piping, elbows, reducers, clamps, sealants, a drill, saws, etc.
3. Cut holes in the bottom of the barrel for drainage purposes and attach diverter valves to the side walls near the top of the barrel.
4. Attach flexible tubing between the diverter valve outlets and connect them to an overflow line leading away from the barrel (this should be slightly lower than the height of the barrel so that any excess water drains out).
5. Securely affix the barrel to the ground with stakes or screws.
6. Connect the downspout directly to the inlet port on the barrel.
7. Check for leaks and inspect all connections before finalizing installation.

Tools and Materials Required for Installation

When installing a rain barrel with overflow, you’ll need several tools and materials including:

  • PVC piping
  • Elbows
  • Reducers
  • Clamps
  • Sealant
  • Drill
  • Saws
  • Flexible Tubing
  • Stakes or Screws

Setting Up an Overflow System

Once all necessary tools and materials have been gathered and the barrel has been secured in place, it’s time to set up an overflow system. This involves connecting flexible tubing between two diverter valves located near the top of the barrel and running it to an alternate location away from the barrel (usually just downhill). This ensures that any excess water will safely flow away without causing damage or flooding.

Checking For Leaks After Installation

After installing a rain barrel with overflow system, it’s important to check for any leaks that may have occurred during installation or over time due to wear and tear. To do this, simply fill up the barrel and observe if any water seeps out from seams or joints. If any leaks are detected, make sure to fix them immediately as they can lead to costly repairs down the road.

Maintaining and Cleaning the Rain Barrel With Overflow

It’s important to maintain your rain barrel with overflow system in order to ensure its longevity and effectiveness. Once every few months, it’s recommended to empty the barrel completely and rinse off any debris or dirt that has accumulated inside. Additionally, make sure to check all connections regularly to ensure they remain tight and secure.

Cost Savings From Using a Rain Barrel With Overflow

Using a rain barrel with overflow can provide considerable cost savings when compared to purchasing bottled water or paying high monthly bills for city tap water services. According to estimates, an average home with a 1,000 square foot roof can save up to $500 per year in water costs by installing a rain barrel with overflow system!

Creative Ways to Use Rainwater Collected in Your Barrels

The rainwater collected in your barrels can be used in many creative ways beyond watering plants and gardens. Some ideas include creating homemade soaps or lotions, flushing toilets, doing laundry, washing cars or pets, filling birdbaths or fish ponds, among others!


Installing a rain barrel with overflow is an excellent way to save money on water costs while helping protect our environment from runoff pollution. In addition to conserving resources, it also allows you to put collected rainwater to creative use in various projects around your home. So if you’re looking for an economical yet effective solution for saving both money and water, look no further – a rain barrel with overflow is your answer!
