1. Check the toilets for leaks - a simple toilet leak can easily overload your system. Easily test for toilet leaks by removing the lid and putting a generous amount of food coloring into the back of the toilet. Do not flush! Wait approximately 20 minutes and if the food coloring makes it into the bowl of the toilet, this is an indication that the toilet is leaking.

The drainfield is a vital part of your septic system. Having the right landscaping on and around your system is important, as tree and shrubbery roots can grow into the drain lines. Also, other heavy items like cars and livestock can break drain lines. Strong roots and heavy items can cause the drainfield to fail. And if the drainfield fails, your system fails. 

1. Do not put too much water into the septic system; typical water use is about 50 gallons per day for each person in the family.
