| Septic Tank Installation Procedures | |
| 1) EXCAVATION • Backfill cover (A) may range from 6" to 30". • Sidewall and end wall allowance (B) should be 18" to 24". • Bedding (C) should be a well compacted sand/gravel mixture: 6" minimum in soil terrain, 12" minimum in rock terrain. |  |
| 2) LID AND MANHOLE EXTENSION • For proper fit, install the lid and/or manhole extension before you put water in the tank and backfill. • Please note the direction of flow - the inlet is higher than the outlet. |  |
| 3) TEE AND GASKET INSTALLATION • Install neoprene gasket into preformed hub area. • Install pipe throught the gasket and make the connection to the 4" sanitary tee using a solvent weld cement. • Put tees directly under manway/inspection boss. • If the tank is equipped with an inspection boss, it can be cut open and a 6" pipe can be placed over the boss and extended to ground level for inspection. |  |
| 4) BACKFILLING EXTERIOR AND FILLING WITH WATER • CAUTION: Start filling the tank with water when you begin to backfill, keeping the water level even with the backfill level as you go. • Backfill in 12" maximum layers with a well compacted sand/gravel mixture. ALWAYS COMPACT ENDS FIRST. • Tamp and compact backfill under inlet and outlet pipe. |  |
| 5) BACKFILLING THE TOP OF TANK • Once the tank is filled with water, backfill to the surrounding level to maximum of 30". |  |
| GENERAL NOTES • Do not install tank in water-saturated clay or in high water table. • Do not install tank across the path of vehicles or heavy equipment. • The tanks are designed for below ground use only. • DO NOT USE A SEPTIC TANK FOR DRINKING WATER. • Immediately refill the tank with water after pumping. • To prevent possible tank collapse, do not use the septic tank (with the exception of the 300 and 500 gallon series) as a holding tank or pump chamber. • It is important to contact your local or state sanitarian regarding proper installation of sanitary tee assemblies. • FAILURE TO COMPLY WITH THESE INSTALLATION PROCEDURES AND GENERAL NOTES WILL VOID THE MANUFACTURER'S WARRANTY | |
