Septic Tank Frequently Asked Questions:

Q: Is it permissible to install a septic tank beneath a driveway?
A: No, installation of a plastic septic tank under a driveway is strictly prohibited and will result in voiding the warranty. It is crucial to avoid placing tanks beneath driveways or in areas with heavy vehicular traffic.

Q: What is the recommended sand/gravel mixture for bedding/backfill?
A: Yes, the recommended mixture for bedding/backfill is the sand/gravel blend commonly known as "pea gravel".

Q: Can a septic tank be used above ground?
A: No, underground plastic septic tanks are specifically designed for below-ground use. Using these tanks above ground can lead to deformation. For above-ground applications, it is advised to utilize storage tanks explicitly designed for such use.

Q: Can hot water be stored in plastic septic tanks?
A: No, plastic septic tanks should not be subjected to water temperatures exceeding 100 degrees Fahrenheit. The maximum storage temperature for polyethylene tanks is 120 degrees Fahrenheit. Exposure to temperatures beyond this limit, even briefly, can compromise the tank's structural integrity, leading to deformation and potential failure.

Q: How do you access underground plastic septic tanks?
A: Each plastic septic tank is equipped with manhole access hatches (1 or 2 depending on the tank). Additionally, risers can be added to the top of the tank for ground-level access. Without a riser, accessing the tank requires digging up the soil above the manway.
