<p>The waste water container for the caravan is coupled to the waste down pipe by an airtight seal (15) with rapid release fastener. The container is airtight and fitted with a venting pipe running upwards to the level of the wash basin, where it is closed. When the waste level reaches the bottom of the waste pipe in the container no more flows out of the waste pipe, giving a clear indication that the container is full. Sufficient space remains in the top part of the container to drain away the water in the waste pipe when the venting pipe is opened. The waste and venting pipes are combined in one unit and sealed by the same seal. The venting pipe can be fitted with an automatic closure as the level reaches the bottom of the waste pipe.</p> |
