Welding And Septic Tank Contents: Why You Want To Be Careful

by Alexa Kim

Septic tank repair services help restore a broken, damaged, or failing septic tank to full use. In some instances, a septic tank may require welding of metals over the holes in the tank to patch it. The patch may give you another year or three before you have to replace the tank entirely. You may be tempted to weld the patches on the holes of the tank yourself, but you should either avoid doing so or be exceedingly careful. Here's why. 

Welders Are Licensed -- Are You?

First and foremost, when a septic tank repair technician gets a welder involved, it is because a welder is licensed contractor that knows exactly what he/she is doing. Welding metal patches on most things is really not as easy as it looks. Even if you, who is not a licensed welding contractor, somehow manages to get the metal patch over a hole, do you know how to make it stay and strengthen the integrity of the rest of the tank? Probably not. 

Methane Is Flammable and Unstable

Methane is the primary gas of sewers and septic tanks. Really high amounts of this gas are present in septic tanks because the tanks are enclosed spaces. Septic tanks have a way of disseminating that gas slowly over time, but the gas can escape more quickly if there is a hole and the hole is releasing the gas faster than a patch can cover it. If you are unaware of this when you attempt to patch the holes yourself, and you light a welding torch close to the escaping methane, you could blow up along with the tank, which will definitely act as a large bomb. 

The Tank Can Heat up and "Cook" Anything That Touches It, Inside or Out

A welding torch is very hot. The heat will transfer from the patch to the tank in the vicinity of the patch. If you accidentally touch the tank, you could burn your flesh. Additionally, if the tank has not been emptied and cleaned completely, you could "cook" the waste inside the tank as the heat spreads across the metal of the tank inside and out. Not only will that create incredibly foul odors, but it will increase the amount of bad bacteria in the septic tank. An increase in bad bacteria inhibits the job of the good (i.e., anaerobic) bacteria, which will make the natural process inside the tank a complete failure

Keeping Our Plumbing On Point

After dealing with a debilitating sewage flood a few years back, I decided to turn my attention to the proper care and maintenance of our septic tank. We had never spent much time trying to keep things in good shape, but we didn't want to deal with another sewage problem. To make things right, we met with the septic tank professionals and talked about how to keep our system in good shape. We worked hard to check for problems, and we called in the professionals at the first sign of trouble. Ever since then, we haven't had any issues. This blog is all about keeping your plumbing on point.
