If you already have a flooded septic tank or leach field, you'll want to get help from a plumber who specializes in septic tanks. But if you don't have a current problem and just want to know how to avoid it, here are a few of the common reasons why septic fields flood.
1. A blockage in the pipes
If there's a blockage in the pipes that lead from the septic tank out into the leach field, water won't be able to flow out to where it normally drains. Because of the way septic tanks are designed, only floating items will be likely to block these pipes. So as long as you never put anything down your drains (including the toilet) other than water and human waste, you should be fine. If you flush down things like cotton swabs, cotton balls, and other types of trash, you're more likely to get a blockage. (And even if you don't get a leach field blockage, you could get a blockage in your indoor plumbing.)
2. Overwhelming the system
There are a few ways you can overwhelm a septic system through excessive use. For example, if you have a lot more people living in the house than the septic system is designed for, or if you divert rainwater runoff to the septic tank, the extra water could be too much for your septic tank or leach field. When the leach field gets totally soaked with water and you keep sending more and more water out, that's when it'll start to flood. You can avoid this by only using the septic system for indoor plumbing disposal (divert rainwater and roof runoff elsewhere) and making sure you know what the specifications of the system are so you can avoid overwhelming it.
3. Flooded surroundings
Whether excessive rainfall has been causing surface flooding in your area, or whether nearby waterways have risen to flood the area your septic system occupies, you should pay attention to your drain field. The best way to prevent this is by simply making sure your septic system isn't on super-low ground that's likely to flood. And if your area is having a record rainfall event or even just a heavy rainstorm, remember that this could combine with heavy indoor plumbing usage to cause a problem if you're not careful.
These are three possible causes for flooding at and around your septic leach field site. If you know your septic system is susceptible to these issues because you've had flooding in the past, be especially careful in how you use your system and consider having a professional like Whitewater Plumbing & Heating Inc take a look to make sure there aren't other issues that could compound the flooding.Share

Having a clogged sink, toilet or shower drain is bad. However, you may feel the problem is worse if you don't have a plunger or snake. But what many people do not realize is that there are many items they have in their home that they can use to remove a clog from a drain. A wire hanger or baking soda and vinegar can both be used to free these clogs. My name is Mark and my goal with this website is to educate people on ways to remove clogs so they do not have to call a plumber for something minor that they can do themselves. Just remember that sometimes a plumber will know best, so don't be too stubborn.
