What can I do as a tenant?
Please ensure that the water flows regularly at all tapping points in your home. Best three times a week. This flushes the water line and avoids stagnation ("standing up") of the water, thus significantly reducing the risk of infestation. If a shower has not been used for a long time, you should let the hot water run off for a few minutes before taking a shower for the first time, open the window and, if possible, avoid staying in the immediate shower area due to the formation of aerosols. The risk of legionella can also be minimized by regularly cleaning and descaling the shower heads, aerators and jet regulators. In the event of a longer absence (holidays, assembly work), the tenants are obliged to leave the hot and cold water running for a few minutes (see table on the back).
Dealing with drinking water after a long absence
A number of factors can affect drinking water quality. This also includes an influence of the material from which the drinking water pipe was made. The quality can change, especially if the drinking water is left standing in pipes for a long time. Homeowners and tenants are responsible for this. Therefore, you need to take care that the water in the pipes does not stagnate.
