Abstract: An adjustable P-trap for a sink is presented. The P-trap has a semi-rigid J-shaped tube with a diameter between one inch and two inches. The J-tube has a long end to connect to a sink drain and a short end to connect to a wall drain. When the long or short end do not reach the appropriate drain an extension tube is cut to length during installation. The long end of the J-tube has threads constructed to receive a threaded adapter and the short end of the J-tube also has threads constructed to receive the extension tube. When a first hose clamp (4a) to clamp the threaded adapter in the long end of the J-tube. When the extension tube is used, the extension tube is mated with the appropriate end and hose clamp is used to secure the two together. The extension tube is then mated to the sink or wall drain.
