The Diverters We Compared

Our research narrowed the field down to several brands and types of diverters that we compared: Oatey, EarthMinded, Clean Rain, Quattro, Raindrop, Wisy, Save the Rain, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We considered a wide range of diverter brands and types. We narrowed it down to downspout diverters that were relatively easy to install and narrowed our focus to our own solution: rain gutters feeding a rain barrel.

We’re always looking for new and better solutions, so if you have a downspout diverter that you swear by, let us know in the comments. We review most of our tested equipment annually so we can try to get it in the next roundup round and see if it will beat out our top picks.

What to Look For

The best downspout diverters have a few features to look for:

1. Value
2. Material
3. Durability
4. Diversion Capacity
5. Versatility

When you get the right blend of these, you can find a diverter that will redirect large quantities of water to your water storage without overflowing. Below, we break down what each of these features means for the rainwater diverters that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something like a diverter shouldn’t blow out your entire budget. They all have very similar costs, so it is easy to budget and predict the cost of a rain barrel project with a diverter.

You never want to spend too much money on one thing when it comes to sustainability gear. It’s better to diversify your projects and budget to make sure you are covered for a wide range of scenarios.

Material

Being outdoors and exposed to the elements, it is important to consider the material type used for the diverter. Brass and PVC are typically the go-tos for outdoor plumbing, and the same materials work well here.

The type of material used also affects longevity and durability.

Durability

Dry rot, UV degradation, and rust are all durability concerns that you don’t want to have to deal with based on the material type, but the material thickness and quality straight from the manufacturer also affect durability.

Diversion Capacity

Diverters redirect water, but usually not all of it. Depending on your downspout size, a diverter may not redirect enough water for your storage solution.

Make sure that your water storage plan won’t be throttled by your diverter. Some diverters also allow you control of the flow, whether it’s the amount redirected or the ability to shut it off completely.

Versatility

Diverters with great versatility offer solutions for a wide range of applications and give you plenty of options when they are in use.

The most versatile models we tested included solutions for different drain pipe sizes and shapes, as well as shutoff valves, flow rate limiters, and debris blockers. Finding solutions that best fit your needs is easier when you pick a versatile model that can adapt to your specific project.

How to Use a Downspout Diverter

Most people install their downspout diverter to feed a rain barrel through a roof gutter system. Different diverter kits use different methods to attach to gutter downspouts.

With some diverters, you’ll need to drill holes in downspouts while others will want you to cut the entire downspout and re-attach it.

Most diverters are difficult to clog with debris, but a leaf guard system for your gutters can help prevent this.

The rain barrel system (or cistern) is important to consider when you are picking the diverter placement. Diverters work with gravity so you will always want plenty of clearance for your storage below. Consider capacity for future expansion as well. We’ve already reviewed rain barrels extensively, so be sure to check out the best rain barrels:

Who Needs a Downspout Diverter?

Everyone needs water and should consider what they would do if the tap runs dry in an emergency. Downspout diverters can help you redirect water into storage containers for better preparedness and/or improved sustainability.

Unlike just feeding a downspout into a rain barrel, they prevent overflow by letting water continue to run through the downspout when the rain barrel is full. This prevents minor flooding and damage to your foundation.

Downspout diverters are suggested as part of a water solution for this kit:
