ABSTRACT:
A washing machine standpipe that has an auxiliary drainage outlet in case the machine pump should break down. Rotation of an inner tube inside the standpipe opens a lower connection to the machine discharge hose, allowing trapped water to escape. When the lower opening is in a closed position, water exits into the standpipe from the top portion as is conventional.
