The downpipes, which transfer rainwater from the gutters to storage tanks or the stormwater system, are an essential part of any house — but they can get blocked or damaged quite easily. So if you want to ensure that your rainwater downpipes are in good shape, watch out for these four warning signs:

1. There Might Be A Problem With Your Rainwater Downpipes If You Have Leaking Downpipe Joints

One of the most common issues with rainwater downpipes is leaking joints. As time passes, the seals around the joints may begin to break down, causing water to leak out into the surrounding walls or ceiling. In severe cases, these leaks can lead to severe structural damage if they're not caught in time.

If you notice cracks or water stains on your walls or ceilings, then it's worth checking each of your downpipes for leaks. If there are any visible signs of wear on the joints, then you'll need to have them fixed by a professional plumber as soon as possible to prevent further deterioration.

2. There Might Be A Problem With Your Rainwater Downpipes If You Have Stains On The Fascia Boards

Have you noticed dark stains on your home's fascias? Watermarks can be caused by leaking gutters. If this is the case, it's possible there is some kind of blockage in your gutter, causing the water to overflow out of the gutter or rainwater downpipes and onto your fascia boards. This excess water can leave unsightly marks on your fascia boards as well as cause them to rot over time.

3. There Might Be A Problem With Your Rainwater Downpipes If You Have Rust On Pipes And Fastenings

When you were first installing your rainwater downpipes, they likely looked shiny and new. Over time, though, they can begin to rust due to their constant exposure to the elements. If you notice rust spots on your pipes, it's best to have them replaced before the rust gets any worse and reduces the integrity of the pipes. Rusting rainwater downpipes can lead to splits. Splits are similar to holes in that water can leak out of them and onto the ground below.

4. There Might Be A Problem With Your Rainwater Downpipes If You Have Sagging Gutters

If your gutters are sagging, it is often because of a defective joint in the downpipe, which prevents water from flowing through the pipe. This causes the water to flow over the top of the gutter and into the fascia board behind it. The weight of the water can cause this piece of timber to rot and sag under its own weight, which makes a mess on your walls and creates a breeding ground for moisture-loving insects.

Your home's rainwater downpipes are an essential component of the gutter system. They not only channel water away from your house, they also prevent water damage to the foundations and walls of your home.
