Drinking water is not only used for nutrition, but also for a variety of other purposes, such. As for body care such as showering and bathing, as water for cleaning or for the washing machine. The proportion of water consumed in connection with food intake accounts for the much lower proportion of total consumption and therefore represents the smaller portion in terms of cost. The much greater proportion of costs is therefore considered to be simple by using water of drinking water quality Household water causes – and here is potential for savings. By using rainwater instead of tap water from Stadtwerke, these water costs are reduced and the environment is protected. For this purpose, rainwater, which often runs unused into the sewage system, stored using a rain collector device and possibly cleaned and filtered. The then in a reservoir, in the form of a barrel or cistern, available rainwater has a quality that allows for use in the home. However, the collected rainwater should not be used for drinking, washing dishes or preparing food. If an underground collection container is used, an official permit under water law may also be required and a notification requirement must be observed.

Basically, and often practiced, can rainwater with an open on top of memory such. B. a rain barrel, field. In low or short-term rainfall, the yield is modest. Remedy can create a container with a larger opening, but take correspondingly more space. A much more effective and elegant solution is to use the much higher collection capacity of sloping or flat roofs and to collect the water draining through gutter and downpipe. In the simplest case, it could then flow directly and permanently into a storage tank via the outlet of the downpipe. This variant has significant disadvantages. The storage tank could overflow uncontrollably, dirt particles from the roof would be stored with and targeted diversion of the fall water into the sewer system would possibly no longer or only cumbersome manually possible if necessary. These disadvantages are avoided by using a device with which the downpipe is tapped, the so-called rain collector. Except for very simple models, it consists of three main components: connection mechanism to the downpipe, integrated water filter and overflow protection for the storage tank with diversion of the sewage into the sewage system at maximum storage level. Common materials of the rain collectors are plastic (PVC), copper and zinc. Particularly durable and corrosion resistant are models made of zinc. The devices are sometimes referred to as a downpipe filter, filter filling machine or variants in the simplest version as Laubabscheider. Most rain collectors are suitable for roof areas of approx. 80 to 100 m2.

To tap the downpipe of some rain collector models, the connector to the storage tank is mounted as an intermediate piece in the downpipe, which must be cut to. Other models can do without such intervention, but they are simply mounted on the downpipe. They pierce the surface during mounting selectively with a thorn and thus produce the removal opening. Very simple models are installed as a drain flap for diverting the water directly into the downpipe. In any case, it must be noted for which downpipe diameter and type the rain collector is suitable. Indicated in the technical descriptions mm and DIN. The cost of installation depends on the type of rain collector and the type of downpipe. As a rule, however, an illustrated installation manual is supplied with the support. Accessories and mounting material such as u. a. Clamps or connecting hoses to the collection container are usually not included and must be procured additionally.

Rain collectors are offered in many variations. In the simplest case, it is a water outlet flap, which is installed directly in the downpipe. Metal models of this type are durable and durable. However, the seals inside must be renewed after some time. Since these absolutely simple rain collectors have no filter, the collected water is only used as service water for z. B. to use garden irrigation. The handling is also somewhat cumbersome because the opening and closing is done manually and an automatic overflow stop when the water tank is full is not integrated. Most manufacturers of rain collectors do not offer such designs, as their use is severely limited. However, they are the cheapest way to collect rainwater.

More comfortable are rain collectors with overflow stop. In this case, the Riesenammler is connected via an additional hose to the storage container. When the maximum level is reached, a valve is automatically closed in the connecting piece to the downpipe and the rainwater drains into the sewage system. The sensors can be based on water pressure, which arises when the storage tank is filled, or the level of the level triggers the switching off, according to the principle of communicating vessels. In the latter case, the connecting piece must be mounted at the same height as the maximum permissible filling level in the collecting container.

Decisive influence on the quality of the collected water has, if present, the filter, whose sieve should be cleaned now and then. A maintenance work of this kind, however, largely accounts for self-cleaning filters. These are low maintenance and do not lose their function in generous periods of time, even with accumulation of dirt. The filters are usually suitable for summer and winter operation and can be easily adapted to the season in the rule. On some models, the filter is changed, in others, it is simply reversed. In addition, variants with multi-stage filter systems are offered, which filter successively in several phases and remain maintenance-free for a long time.

Even more comfort is provided by rain collectors with overflow stop and filter. They clean the water and also keep larger particles like u. a. Leaves and needles back. These models and the variants that only have an overflow stop are often referred to as rain collector machines.
