The T-H Marine 18” Overflow Drain Tube – Straight with Screen is the most trusted and original solution in livewell plumbing.
This drain tube is designed to fit all T-H Marine 1-1/2 inch thru-hull fittings, combining overflow and drain functions in a single, efficient setup.
Each tube features a rigid white PVC standpipe and a flexible, tough vinyl boot end for a snug, watertight fit.
The tube and boot's outside diameter is 1-5/8 inches, specifically sized to fit securely into 1-1/2 inch thru-hull drains.
This ensures a positive seal without tools, adhesives, or clamps.
To operate, simply insert the boot into the thru-hull.
When ready to drain the livewell or baitwell, just pull the tube from the top — no need to reach into the water.
The included screen helps block debris and can be trimmed to custom lengths as needed.
Built from marine-grade PVC, this overflow tube is durable, chemical-resistant, and ready for long-term use in freshwater or saltwater environments.
Designed for floor drain installations, straight tubes are ideal for draining through the bottom of the well.
