Fiberglass/Plastic Septic Tank-Plastic septic tanks are largely impervious to the rusting and cracking of steel and concrete septic tanks.As with any septic tank, keep close attention to the baffles (entry and exit points) as they tend to corrode first. If you’re buying a house or living in one that had a pre-existing steel septic tank, manually inspecting this steel cover is not necessarily a good indication of the general condition of your tank. These covers can be replaced without replacing the entire tank. Steel top covers can rust through and cause an unsuspecting person to fall into the tank.


Designed to last no more than 20-25 years, they can be susceptible to rust even before that.
