Popular additions and accessories include:
Holding tanks are a vital component of a boat's plumbing system and should not be overlooked when undergoing repairs. It is critical that you accurately measure the storage compartment that the tank will actually be stored in as the vast majority of our tanks are normally bolted into their location. Securing of your tank's to the boat's deck help avoid messy accidents and unnecessary spillage of tank contents.
Another key benefit of using a plastic water holding tank for your boat is the material is less likely to retain odor after the contents have been emptied.
All of our marine water and waste holding tanks feature female NPT (National Pipe Threads) for easy adaptation and integration with existing plumbing systems.
