Ensures a calm inlet of rainwater within the storage tank. Fine dirt particles remaining in the water slowly sink to the bottom, forming a Sediment layer. sediment layer, which has been proven to have a positive influence on the stored rainwater. Rainwater storage tanks with a sediment layer have clearer water. The calm inlet of water prevents this sediment layer from being stirred up. At the same time, oxygen is supplied to the lower part of the stored water. The oxygen prevents anaerobic decomposition in the cistern. The water remains fresh. The 3P Calmed Inlet is the 2nd cleaning stage in the rainwater storage tank.
