Myth: “My neighbor/ friend/ etc. hasn’t had their septic pumped in 20 years! I don’t need to have mine pumped so often.”
Fact: These are VERY rare cases, when all conditions are perfect. Just because their system has had such good fortune, doesn’t mean yours will! Good maintenance is to pump every 1-3 years and add bacteria for a safe and problem free system. The State of Wisconsin does require pumping every 3 years.
Myth: Adding yeast to the septic will help prevent problems.
Fact: While yeast does help to break down a small percentage of waste (starches only), it will not help with the majority. In addition, it does not actually produce good bacteria, which aids in the liquefying process. So yeast may help in a small way, but is generally not worth the effort.
