While modern septic tanks made of steel or fiberglass have a life expectancy that could easily last 40 years or more depending on variable factors, a steel tank could start to see deterioration in as little as 15 to 20 years. If you are living in a home that is showing signs of septic tank deterioration, you will be facing the task of replacing your outdated tank and it should be done quickly to prevent soil contamination. Here are a few of the biggest questions homeowners tend to have when it comes to replacing their antiquated steel septic tank with a new, updated version. 

How much will a new septic tank cost?

Septic tanks can cost, on average, $4,587 to have installed. Of course, this price can vary according to several different factors, including:

• the location of the tank
• the difficulty of removing the old septic tank 
• the type of terrain involved in the excavation process
• whether there are tree roots that will have to be removed during installation

Will only the septic tank have to be replaced or other parts of the system as well?

In most cases, the lines of the septic system will hook right into a new tank without a lot of hassle and without the need to install new components. However, if your septic system is excessively outdated, the lines may need to be replaced to bring the whole system up to functional and modern standards. For example, it was not uncommon years ago for cast iron to be used for the main outlet lines coming from your home to the septic tank, and these lines are prone to leakage and deterioration so they would likely have to be replaced. 

How can you maximize the lifespan of your newly installed septic tank?

Once you have your new septic tank in place and have made the investment, there is no doubt you will want to maximize your investment by keeping your new tank in tip-top shape. There are several things you can actually do to prolong the life of your new septic tank. Make sure you follow flushing guidelines by not flushing chemicals down the toilet or pouring them down the drain. Avoid planting trees around your septic tank because the root system can eventually cause problems. Additionally, you can usually prolong the life of your septic tank by having it cleaned and pumped regularly. For more info, contact a company like Honest John's Septic Service Inc.
