Frequently Asked Questions

Yes, a septic tank can float up under certain circumstances. This phenomenon, known as “septic tank flotation,” occurs when the groundwater level rises due to heavy rain or other factors. When the water table increases, the buoyant force can cause the septic tank to lift from its original position. This can disrupt the system’s functionality, leading to leaks, structural damage, and drainage issues. Proper installation techniques, including anchoring the tank and considering soil conditions, can help prevent septic tank flotation and its associated problems. Regular maintenance and monitoring are essential to address any potential issues promptly.

The frequency of septic tank pumping depends on various factors such as household size, tank size, and usage habits. On average, it’s recommended to pump a septic tank every 3 to 5 years.
