What’s a Rain Barrel Diverter?

Best rain barrels

A rain barrel diverter is a device used to direct water from your downspout and into your rain barrel for the purpose of water conservation and reusing.

It’s connected to the downspout and once the barrel is full, it automatically sends the water back to the downspout and directs it well away from the basement or foundation of your house.

The rainwater that’s collected can then be used for several purposes such as irrigating the garden or lawn, washing your vehicle, driveways, sidewalks or even your pets (if the water is free of debris). 

A rain barrel without a diverter can overflow, impacting your house and garden. It can affect the foundation and walls of your home, resulting in damage, mold and fungi growth. However, by installing a diverter, you can easily avoid these impacts by removing excess water ponding around.

These devices are uncomplicated, simple objects that can easily be fitted to your downspout with a little DIY knowledge or with the help of a plumber.

Types of Rain Barrel Diverters

There are two types of commonly used rain barrel diverters: Y connectors and hose models. Let’s take a look at the difference between the two.

  • Y Connectors
Y connector rain-barrel diverter

Standard Y-connector

These are the most basic type of diverter. It has an arm which directs the water to the barrel below.

Although this model doesn’t have a filtering system for debris, they still work very well and are durable and reliable. They last longer since they don’t come with extra parts that could get lost, dysfunctional or corroded.

The endpoints of the Y shaped diverter channels rainwater to the barrel or wherever you decide to terminate the downspout.

Installing it can be a bit difficult because of its shape and during winter there is a possibility that it could freeze since these models are a little bulky.

  • Hose Models

This type of diverter is perfect for use during the summer. To attach a hose model diverter, you’ll need to cut the downspout and connect the diverter with a connecting hose.

Hose diverters (also called ‘inline’ diverters) are quite easy to maintain during winter since you just have to cover the outlet to prevent it from freezing.

When you leave the spigot open and ‘winterize’ the barrel, no water can get in so there’s no chance of it freezing.

How to Choose a Rain Barrel Diverter

Rain barrel diverters are useful tools to have so when choosing one, it’s important to take the following factors into consideration to make sure you buy the best quality model to suit your needs.

Here’s what to look out for when choosing the right rain barrel diverter for your home.

  • Size – don’t forget to check the size of your existing downspout system so that you can choose the right sized diverter for it. Most diverters come in 2 x 3 inches and 3 x 4 inches, but double check to make sure or you might end up buying the wrong product.
  • Design – rain barrel diverters are available in various designs. You’re likely to come across models that fit circular and rectangular downspouts so when making your purchase, ensure that the design will match the one of the downspout you have.
  • Material – choose a diverter that’s made from durable and sturdy materials with the ability to withstand heavy rains and extreme weather conditions so that you’ll get optimal performance for a longer period of time. Therefore, don’t choose a cheap product that’s made of low-quality materials since it might get damaged quickly.
  • Ease of installation – this is one of the most important points to consider. Opt for a diverter that’s easy to install since the last thing you’d want to do is spend hours trying to install it by yourself and finally resort to seeking professional help. The ideal diverter model should take less than 5 minutes to install. If you’re going for a DIY kit, make sure it comes with all the required parts for easy and seamless installation.  

How to Install a Rain Barrel Diverter

Installing a rain barrel diverter isn’t a complicated process and shouldn’t take you a lot of time. If you’ve got your rain barrel and purchased your diverter, then next step is to install it correctly.

The diverter kit you’ve purchased should include the diverter component that’s going to be inserted into the downspout as well as the hose which connects it to the barrel.

The kit should also include screws, caps for the diverter’s side spout and a couple as well. Some kits even include a hole saw in case you need to drill holes into your downspout.

Generally, you would require some basic tools. These could include:

  • A screwdriver
  • A tape measure
  • A level
  • A hacksaw
  • A knife
  • Pair of scissors
  • Silicon seal
  • The diverter and its components

Now that you’ve got your kit ready and you’ve decided where your barrel should go, let’s go ahead and set up your new diverter.

  1. First, make sure your barrel is elevated off the ground with enough room to connect a hose to the spigot on the bottom. Once the diverter hose is attached to the barrel, both the diverter and the barrel should be at equal height so that water will not run uphill.
  2. Using a level, mark the height of the barrel on the downspout. If the barrel hasn’t got a hole, drill one in the side and insert the couplet.
  3. Following the instruction manual, mark the bottom and top cut points on the downspout. This is the outline of the area that’s going to be removed and replaced by the diverter.
  4. Using a hacksaw, make the cuts in the downspout, removing that segment of it.
  5. Replace the cut-off section with the diverter and screw it in according to the instructions.
  6. Cut the hose to the right length to reach the water barrel. If it has too much slack, the water won’t flow properly so watch out for that.
  7. Attach one end of the hose to the couplet on the side of the barrel and the other end to the diverter and that’s it. You’re done!

Pros and Cons of Rain Barrel Diverters

Although rain barrel diverters are not a mandatory requirement for rain barrels, they are very useful and come with many benefits. In fact, they hardly have any disadvantages at all.

Checking out the various benefits of rain barrel diverters may help you decide if you actually need one and whether to go for it.

Pros of Rain Barrel Diverters

  1. Saves water – Diverters help with conservation of H2O, one of our most precious natural resources. You will be able to make the most of your rainwater gushing down the downspout. While rainwater harvesting is one of the oldest methods of water conservation and usage, always double check the state regulations regarding rainwater harvesting as this can vary. Some states have prohibited rainwater harvesting so check this first to avoid getting penalized. Once you’ve harvested rainwater, you can use it for a variety of functions.
  2. Keeps your rainwater clean – Diverters create a sealed system, preventing insects and mosquitoes from getting inside the rain barrel. This ensures that your water is protected from unnecessary contamination.
  3. Diverters save you money – Using a rain barrel with diverter ensures that you make the most of your rainfall and creates an independent water supply for your home. The less municipal water you use, the lower your water bill.  
  4. They’re easy to maintain – Once you’ve set up your diverter, there’s little to do but to ensure that it’s functioning correctly with no clogging. Also, since diverters self-regulate, you won’t need an overflow hose. Simply check on it every now and then.
  5. Diverters filter out debris from water – Some diverters come with a filter to remove large particles and debris from the rainwater. However, not all have this option so double check prior to purchase. If the model doesn’t have one, you may need to purchase a gutter guard to keep out leaves, twigs and insects from getting into the water and clogging it up.
  6. Diverters protect your house – A rain barrel without a diverter will overflow easily, collecting on the ground to create ponding. This can damage the foundation of your home and cause algae and mold to grow on the walls. By using a diverter, the water is directed away from the area and overflow is taken care off. Your house remains protected.
  7. Independent water supply – Having a rain barrel is useful for dry areas and in emergency situations, as long as the state regulations allow you to have one. By installing a diverter, you’re making this system even more efficient.

Cons of Rain Barrel Diverters

  1. Sometimes complicated to install – This depends on your specific piping and downspout, but some rain barrel diverters can be complicated and will require professional plumbing. This can get expensive and take time. However, once installed, there’s little to do.
  2. High-quality models can be pricey – In general, rain barrel diverters cost around $20 to $30, but some higher quality models can cost upwards of $40. In the large scale of things, this is a small cost to pay and it’s well worth its price. But for some people, it might make more sense to create a DIY rain barrel diverter instead of spending money buying one.
