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.
