Abstract: An improved drain trap assembly which is designed to allow for disposal of sediment with reduced mess and uncleanliness. The improvement comprises a valve which is attached to a drain trap and a compressible container attached subjacent to the valve which collects the sediment. The container when compressed forces residual fluid through the valve such that the valve can be closed to prevent flow of residual fluid back into the container; thereby, the volume of residual fluid in container is reduced prior to removal of container from drain trap. The container is then removed and the sediment is either discharged from the container or the disposable container is discarded. A reduction in discharge of unclean residual fluid into the surrounding area is accomplished by the improvement.
