The T-H Marine 18” Overflow Drain Tube – Straight with Screen is the original and most trusted solution in livewell plumbing. Designed to fit all T-H Marine 1-1/2 inch thru-hull fittings, this drain tube combines overflow and drain functions in a single, efficient setup. Each tube features a rigid white PVC standpipe and a tough, flexible vinyl boot end for a snug, watertight fit.
