Common problems with rainwater drains

Ensuring your home's rainwater drainage system is functioning correctly is crucial to prevent costly water damage and structural issues. Discover the common pitfalls of downpipes and learn how a professional building inspection can safeguard your investment and provide peace of mind.

Downpipes are designed to transport rainwater away from the roof and gutters, to the sewer system, to a gravel pit, or to an above-ground point in the garden. It's important that rainwater is drained away from the roof and gutters, but it's also crucial that it's transported to the correct location. If rainwater collects in the wrong place, it can have unpleasant consequences. During a building inspection, you can have a complete home inspection. This includes checking the condition of the downpipes. Homekeur provides insight into four of the most common problems with downpipes.

1. Damage and defects to the rainwater drainage system

Various types of damage and defects occur in rainwater drains. In many cases, this involves mechanical damage or defects that can be repaired relatively easily, for example, by replacing a part with a new one. Such problems can usually be resolved quickly and relatively inexpensively.

2. Shifting and subsidence of the drains

Rainwater drains can shift over the years, for example, drifting apart, but they can also subside. This often leads to connections becoming defective, requiring repair for optimal functioning. If necessary, components can be replaced immediately. In many cases, such repairs and replacements are quick and easy.

3. Incorrect location of water collection

It's more common for rainwater drains to end above ground instead of below ground, near the sewer system . This doesn't necessarily have to be a problem, but it can certainly happen. Therefore, always have this checked thoroughly during a building inspection. If water collects at the wrong point and can't drain easily, this can cause problems. For example, if water collects against the facade and has difficulty draining away, the rainwater will seep into the facade, with all the ensuing consequences. If the water collects at the right point and can drain away easily, then there's nothing wrong, and you don't need to make any changes.

4. Insufficient storage capacity in the (gravel) pit

Rainwater drains can also end in a (gravel) drain. This can be fine, but it's important that the groundwater drain has sufficient retention capacity. If not, the facade will be heavily loaded by the water, causing moisture problems. Ultimately, this can lead to major problems that are often not immediately detected. These can include weakened soil structures and foundations, or defects in basement walls and floor joists.

If something isn't right with your rainwater drainage system, it can sooner or later lead to serious problems. You'll then face high costs, and you naturally want to avoid this.
