Tips To Prevent Washing Machine From Impacting Your Septic System

Washing machines are known to be the number one reason for septic tank failure. Hence, it is important to take measures to ensure that you do your laundry without damaging or blocking the septic. While buying one of the energy-saving washing machines for septic system mentioned above is an ultimate solution, here are some tips to do laundry safely with your existing washer.

Install a lint filter: These specially designed filters are designed to catch lint present in the waster expelled by your existing washing machine. The lint filter can be attached to the discharge hose of your appliance. You can easily install it yourself and reuse it too, but it should be emptied every two weeks depending on machine use.

Effluent filters: Again, these are specially designed filters designed to prevent the large pieces of dirt or debris from entering the drain pipe and causing a blockage. The effluent filter is installed at the back of the septic tank.

Save water by doing full loads: We recommend that you only do full loads and spread them out to avoid overloading your septic.  Also, consider using liquid detergent instead of powdered ones for less pressure on septic.
