When you buy a home the last thing you think about is the septic tank that is coming with it. However, how that system was maintained could very well be the make or break factor in purchasing that property. There is relatively easy things you can do to your system to keep it properly maintained, and if done regulary you will be able to use this maintentaince to your advantage when trying to sell your property. We probably don't realize it, but every time we send any kind of wastewater from our households, we are putting our septic tanks to work. How we take care of this tank and system can help our houses for years to come. With proper maintenance a septic tank system can last upwards of 25 to 30 years and can also be a selling factor when trying to move.
