Not everyone has a basement to their house, but to those who do, they might find it a challenge to keep the water out during a flood. This is not as much of a problem for a house on a slope, as the water can drain downward, but a basement on flat ground is just a sinkhole for stormwater. If that water has to deleaded before it enters the public drain network, consider buying Stormwater Catch Basin Inserts in advance.

Natural rainwater is mostly pure H2O when it is falling in the air. The problem is that when it hits the ground it becomes runoff and can pick up all sorts of contamination. Rainwater running off of shingles might pick up heavy metal from the asphalt, and of course, water near a road might have the same problem. The more urban then environment, the more severe will be its pollution. The laws are about keeping drinking water pure.

Another reason to filter water is for a personal cistern. Some people live in areas where rain is sporadic and water costs are high. They solve the problem by capturing runoff and storing it underground. This can be an excellent source of extra water, but it still might need to be filtered if it comes from the roof or the soil. Often more water is caught than pours onto a concrete basin.

The fix is to have a single drain with a good quality filter. The filter for cistern water can be rough or fine, depending on the use of the water, but it is great to remove heavy metals ahead of any real use. A filter might not be able to remove chemicals, but it can easily remove metal and lifeforms. Keeping it replaced on time ensures that the benefits never end. It is still a good idea to run drinking water through a finer filter before use.

The most important reason to buy new filters is just that they tend to get clogged the same as air filters. The quality deteriorates, and small debris can eventually fall beyond the surface guard. Stormwater Catch Basin Inserts tend to be large and robust, but they do eventually get clogged.

Replacing the filter ensures that its functions properly and that the garage will not become flooded. Old filters become clogged or jammed by debris that clogs their intake. Since the bypass defeats the whole point of a filter, stay compliant and keep the insert replaced on time.
