Types of Downspout Filter

Before we jump into the buyer’s guide of downspout filters, you need to know how many types there are. Otherwise, you won’t even know what to buy.

Although there aren’t many variations, still, to meet your needs, you have to know these things.

Flexible:

Flexible downspout filters are the most common type of downspout filters. Most people buy this variation and there are reasons behind it too.

You see, flexible downspout filters are easy to use. These are quite bendy and flexible hence the name flexible. And most importantly, they’re cost-friendly too.

However, it has some drawbacks. In order to make these so flexible and inexpensive, manufacturers have to use cheap materials such as thin plastic. And sometimes that can damage the pipes.

Roll out:

Roll out downspout filters come with a pipe that can out when it detects water. After the water is gone, it’ll again roll-up. This feature makes these filters more convenient as visibility won’t be a problem.

The best part is if you have kids or pets that run around the house, they won’t trip over the filter.

However, like all downspout filters, it also has some problems. Stones or soil can sometimes get stuck in the pipes or the filter itself. Then, you’ll have to manually fix it to get it up and running again.

Other than this problem, it’s quite good. The functionally and discreet appearance makes it a good choice.

Flipper or Hinge:

Lastly, we have flipper or hinge type downspout filters. As you’d guess, you can flip up or down this filter anytime you want.

While they are better than other filters, they are more expensive too. They’re made out of metal and other premium materials, so it makes them more durable and obviously more expensive.

However, if you want to bend it, that’s a big no. You can’t really bend metal easily, can you? Other than that, it’s quite good.

Benefits of Using a Downspout

We all know what downspouts do. But some people are not aware of the benefits of using a downspout. So, let’s see what all the fuss is about-

You get to prevent mold:

Mold can grow anywhere as long as it finds moisture. Not draining the moisture the excess moisture or water can lead to an attack of mold. So, you shouldn’t take that chance.

Most importantly, mold can be a very difficult thing to get rid of. They can grow anywhere and it starts breeding, there’s no going back for it. It’ll spread like wildfire.

It’s not like you can’t remove it. But the amount of work you’ll have to put in can feel overwhelming. You have to use special chemicals.

And that’s not all. Sometimes you’ll even have to strip off the paint of your house. Then apply different kinds of sealants and the list doesn’t stop. So, you understand how moisture can lead to a horrible situation.

Moreover, mold is quite harmful to the human body. Without this, you’re basically putting your whole family in danger.

Once you start removing mold from your house, the process will get more and more expensive. On the other hand, buying a downspout won’t cost you anywhere near that.

So, you decide what you want. Thousands of dollars for mold removal or a few bucks for a downspout. We’d go for the downspout.

Apart from mold, it’ll also keep away the unwanted rainwater from your house and maintain a healthy and fresh home.

You’ll protect the foundation of your house:

Water is always bad for a house. Well, not always bad. A little rain is good actually. The temperature goes down in your house and it stays cool for some time.

However, the problem starts when it stays there for a long time. Sooner or later, it can do some damage to your house.

When your house won’t have a downspout, the water goes down to the foundation of your house. You won’t feel it immediately. It may take years. But after that, you’ll notice that the foundation started weakening. 

And that’s when the real problem will start. You see, when a lot of rainwater gets into the ground of your house for a long time it softens the root. And this is not something you can fix easily.

Even if you spend a ton of money it’ll take a long time. Trust us on this, you don’t want to get into that mess.

That’s the whole point of a downspout. It’ll direct the rainwater to another place, securing the foundation of your house.

You get to store fresh rainwater

Apart from protecting the foundation of your house and preventing mold, a downspout can help you store water. Storing rainwater with a downspout is incredibly easy.

All you have to do is place a barrel or a container at the end of the downspout. You can use it anytime you want.

Let’s say, you have to wash your car but there’s no water supply. This storage can come in handy then.

Moreover, you can also use it to water the plants in your garden. No matter how you see it, you’ll always save some bucks on your water bill.
