If <br /> a "Zabel" PDS-PF-1.5/2.0 Pressure Filter or a "Sim-tech" Pressure Filter <br /> is a better option it may be installed in the supply line in the pump <br /> chamber, and to be easily accessible from the ground surface for <br /> cleaning. (The pump alarm will sound when this filter clogs) <br /> All run-off water is to be diverted away from the tanks and drainfield <br /> areas <br /> Plastic bolt down manhole covers are to be used and left at grade level <br /> for maintenance access. <br /> Blowout valves are to be installed on the end of all pressurized laterals. <br /> These will need to be in a protective housing and accessible from <br /> surface grade. <br /> Pressure rate glue joint fittings must be used. <br /> No Fernco's will be used in pressure lines. <br /> If the septic tanks are less than 3' deep the covers are to be insulated <br /> with 2" high-density foam <br />
