3 Things Every Homeowner Should Know About An Aging Steel Septic Tank

Before septic tanks of concrete and fiberglass became the most common types installed on residential properties, most homeowner relied on a steel septic tank because the material was more readily available. If you live in an older home, there is a good chance that the septic tank you have in your backyard is made of steel as well. While the septic tank may seem to be serving its purpose, as a homeowner, there are a few things that you should know about this type of tank. Here are three things you need to know and keep in mind if you have a steel septic tank on your property. 

Steel septic tanks do not have a very long life span. 

Compared to other septic tank types, steel is the one that has the least attractive life span. In fact, most steel septic tanks will only last for about 15 to 20 years before they should be replaced--even though many homeowners keep a steel tank for far longer than that. In comparison, a concrete septic tank will easily last 40 years or more and a plastic or fiberglass tank will usually last just as long. The lengthy life span is the primary reason the transition was made to other materials over time. 

Septic tanks made of steel can be prone to rust and deterioration. 

If you have a steel septic tank that is getting near the end of its life span, there is a good chance it has already started to corrode and rust. The baffles can rust sooner than anything else and this causes drainfield clogging. The bottom of tank can also start to deteriorate, leaving waste to leak out beneath. Additionally, steel tanks usually have a basic sheet of steel covering the opening of the tank and this can break easily due to corrosion. 

Acidic soil levels can cause a steel tank to break down much faster than usual. 

If you have a steel tank, it is a good idea to keep tabs on the pH levels of your soil. If your ground has high acid levels, the tank will start to corrode and rust much faster than usual. Therefore, you should not be surprised if you start to see the walls of your steel septic tank start to break away. If you determine your soil has high acid levels and you have an older tank, it is a good idea to have a professional take a look to determine the condition of your tank.
