The power supply and <br /> switches must be located outside the manhole and pumping chamber in a weatherproof enclosure. A <br /> warning device must be installed with light and sound devices;this is in case of a pump failure.The <br /> manifold and supply line must have back drainage to the pump chamber.The rock and fill materials must <br /> be clean.The sod layer below the entire mounded area must be turned over.Just break up the sod and be <br /> sure not to over work. <br /> Not6in�other than grav water (laundrv showers etc.) Human water and toilet tissue should be <br /> disposed of into the septic tanks Garbage disposals are not recommended. Additives must not be <br /> used•they mav cause harmful damaee to vour septic svstem.
