Frequently Asked Septic Tank Questions
1. Can I install a septic tank under a driveway? No, installing the plastic septic tank under a driveway is not permitted and will void the warranty. Do not locate tanks beneath driveways or in the pathway of heavy or vehicular traffic areas.
2. Is there a sand/gravel mixture recommended for bedding/backfill? Yes, the sand/gravel mixture, commonly called “pea gravel” mixture is recommended.
3. Can I use a septic tank above ground? Underground plastic septic tanks are designed for below ground use only. Using the tanks above ground can result in deformation of the tank. It is far more cost-effective to utilize an above ground storage tank that is specifically designed for above ground use and applications.
4. Can hot water be stored in plastic septic tanks? Do not subject the tank to water temperature higher than 100 deg F, polyethylene storage tanks have a maximum storage temperature of 120 deg F. Contents with a temperature in excess of 120 def F, even for a short period of time, can weaken the tank’s structural integrity and make it susceptible to deformation and failure.
5. How do you access an underground plastic septic tanks? Each plastic septic tank comes equipped a manhole access hatches.
