7 Best Rain Barrel Diverter Reviews 2022 – Buying Guide For Newbies

Harvesting and conserving rainwater has been a common practice in the United States for many years. It’s almost impossible to come across a home that doesn’t have a rain barrel for saving the collected rainwater. However, it is important to have a diverter as well and not just anything but the best rain barrel diverter you can possibly find as many things depend on it.

A rain barrel alone isn’t enough for harvesting rainwater. Adding a diverter to your downspout gutter system makes it even easier to harvest this water. The best rain barrel diverter helps prevent overflow in your rain barrel. It automatically channels the excess water once your barrels are full—preventing overflow that can cause costly damages to your basement or house foundation.

If you’re not familiar with these diverters, choosing the right model for you might not be a walk in the park. You’ll get easily confused with the multiple options available on the market. Lucky for you, our in-depth guide below will help you choose the most suitable model for you (plus, we’ll give you a list of the 10 top-rated diverters on the market right now).

Why Use a Rain Barrel Diverter?

A rain barrel diverter is a crucial tool for any homeowner who wants to hassle-freely and effectively harvest and conserve the rainwater.

How it makes harvesting rainwater easier?

Well, a typical rain barrel diverter connects to your downspout system and then channels water to your rain barrel until it gets full.

Once your barrel gets full, the divert will then automatically start sending the excess/unwanted water through downspout and away from your home foundation. This way, it’ll help prevent the foundation from getting damaged and costing you money to repair it.

Aside from facilitating effective water entry into your barrel, a diverter provides you with additional benefits as listed below:

  • It restricts debris (e.g., dirt, leaves) from entering the rain barrel. Instead, it channels them down the downspout, unlike in the barrels without diverts which usually have a cloud of debris at the top.
  • It forms a sealed system that prevents mosquitoes, pests, algae growth causing sunlight, etc., from surviving inside your barrel.
  • It eliminates the need for installing an overflow hose. This is due to its ability to prevent overflow in your rain barrel(s)

Even if you’re not interested in harvesting rainwater or don’t have rain barrels, we still advise you to fit a diverter in your home downspout system. This is crucial to help channels water at least 10ft away from your home—to save your foundation and basement from damages.

As we’ve just said in the intro, the market has all sorts of rain barrel diverters to ensure you find the most suitable model for your specific needs. Whether you have a round or rectangular downspout, you’ll surely find a diverter for you.

Key Factors To Look For Before Buying!

When buying a diverter, make sure you focus on the critical factors outlined below to ensure you get the best rain barrel diverter for your specific needs:

Type of diverter

First, you’ll need to determine what type of rain barrel divert you want to buy.

We can group the diverters into two main types namely:

1. Hose or inline rain barrel diverter

This is the type of model which require you to cut your downspout and then insert the diverter with the connecting hose.

Many homeowners prefer an inline diverter because it’s extremely easy to maintain during winter as you can simply cover its outlet to prevent water from getting in.

2. Y-connector rain barrel diverter

As the name suggests, a Y-connecter features an arm for directing eater into your rain barrel. Because this model doesn’t come with many external parts that can easily get lost, dysfunctional or corroded, it usually lasts longer and is also easy to install.

Due to its shape, however, a Y-connector might be a bit challenging to install because you’ll need to offset it from a straight path. They might also easily freeze during winter due to the bulkiness associated with them.


You should also look at the size of the diverter you plan to buy to ensure it’ll fit in your existing downspout system.

The diverters usually come in sizes 2 x 3 inches or 3 x 4 inches. And the ideal size for you should be directly dependent on your residential downspout size.

If you buy the wrong size of a diverter, it’ll not work according to your expectations!

Ease of installation

You should also ensure that the diverter you buy is extremely easy to install. An ideal model should take you around 10-20 seconds to set up.

If you’re buying a DIY diverter kit, makes sure it comes with all the parts needs for complete installation. This will help ensure you’ll not have any problems once you start putting it up.

Also, check that the diverter you buy comes with a set of detailed, well-illustrated instructions to guide you through the installation process.

If the manual isn’t included in the package, make sure you can at least access it online or from the manufacturer upon request.

Ease of maintenance

It’s important to take care of your rain barrel diverter, especially during the winter months, to ensure it doesn’t get winterized/damaged.

That being said, we have noted that the best models come with a winter hole cover that prevents freezing in the diverter—thus preventing possible damages.

Some models are designed in such a way that they’re easy to detach during the winter season. This means you can easily remove them during winter or when not in use.

Pro TIP: Read user reviews!

Before you buy that rain barrel diverter, make sure you go through the previous users’ reviews. Here, you’ll find some firsthand info on how effective the diverter you’re planning to buy is when it comes to helping you collect rainwater while preventing barrel overflows from damaging your foundation.

How To Make Your Own Rain barrel Diverter?

Below, we’ve attached a video (a quick, easy-to-follow guide) on how to come up with your own rain gutter diverter from start to end.

Follow this guide, and you’ll end up with a highly functional high-flow downspout diverter:

How Does It Work?

If you’re used to harvesting rainwater, then you know that this task has its own challenges. The most common problem is rainwater barrel or collector overflow…mainly due to heavy rains (in the summer).

The problem with your rainwater barrels overflowing is that the excess water may leak into your house foundation and basement. Needless to mention, water seeping into your house foundation or basement can cause costly damages.

That’s where a rain gutter diverter comes in…

It helps direct just the right amount of water into your rain barrels.

When the barrels are full of rainwater, the diverter will then automatically channel off all the excess water to the downspout.

The downspout will then drain this excess water away from your house foundation or basement. (Problem solved! You don’t have to worry about foundation damage again).

How To Connect It To a Barrel?

You don’t need any prior experience or special skills to be able to connect your new diverter to your rain barrel.

The MOST important thing here is to determine where to place your diverter. If you place it too low or too high, it might affect the flow of rain water into your rain barrel.

Here’s how you determine how to place it:

Use a tape measure to measure the top of your rain barrel and mark the first line. This should be the most appropriate place where you should connect the diverter to the barrel.

Check the video below on how to connect your diverter to the barrel…

TIP: Though the connection process is usually the same for all the diverters out there, we suggest that you check your diverter manual for more details specific to it. This will go a long way in ensuring you properly connect your diverter to the rain barrel.
