Overflow Drain Tubes-Threaded Drains

SKU: TH-1502T



T-H Marine pioneered the use of the overflow drain tube for boat livewells. The original overflow drain tubes are still the best in the industry. Our tubes provide a very functional way to plumb a livewell. Using our overflow tubes means you only need one hole in the livewell and one fitting to serve as both the overflow and the drain. Instead of reaching into the water and getting wet to pull a drain plug, you simply pull the tube out from the top and draining begins.

  • Functional and economical overflow drain tube
  • All marine grade PVC construction for long life
  • Sure sealing of live-well / bait-well drain
  • Makes draining live-well / bait-well easier than a plug
  • Tubes available for multiple size fittings to cover every size of live-well drain
  • Custom lengths of tube available for boat builders to fit your live-well capacity
  • Aftermarket versions come with screen loose, so they can be cut to best length
  • Straight tubes for draining through floor, 90 degree tubes for draining through side wall

NOTE: Any tube can be cut to custom length for boat manufacturers. Specify the desired length by adding it at the end of any part number. For example, to request an 8" length of the ODT-1, the correct part number is ODT-1-8.

Threaded Drain Fitting

This fitting allows for the use of the screw-in drain tubes. A must-have for large livewells. I won't ever have another one without these.

Great product

Built a 60gal baitwell for my flats boat and this was a perfect fit to handle a 1500gph aerator pump
