Professionals should refer to the O/M Manual for detailed <br /> checklists for tanks,pumps, alarms and other components. Call 800-322-8642 for more details. <br /> • Written record provided to homeowner after each visit. <br /> Plumbing/Source of Wastewater <br /> • Review the Water Use Appliance Chart on Page 5 with homeowner. Discuss any changes in <br /> water use and the impact those changes may have on the septic system. <br /> • Review water usage rates(if available)with homeowner. <br /> Septic Tank/Pump Tanks <br /> • Manhole lid. A riser is recommended if the lid is not accessible from the ground surface.Insulate <br /> the riser cover for frost protection. <br /> • Liquid level.Check to make sure the tank is not leaking.The liquid level should be Ievel with the <br /> bottom of the outlet pipe.(If the water level is below the bottom of the outlet pipe,the tank may <br /> not be watertight.If the water level is higher than the bottom of the outlet pipe of the tank, the <br /> effluent screen may need cleaning,or there may be ponding in the drainfield.) <br /> • Inspection pipes.Replace damaged caps. <br /> • Baffles.Check to make sure they are in place and attached,and that inlet/outlet baffles are clear <br /> of buildup or obstructions. <br /> • Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation. <br /> Recommend retrofitted installation if one is not present. <br /> • Alarm.Verify that the alarm works. <br /> • Scum and sludge.

Check for surfaced effluent or other signs of problems. <br /> • Gravity trenches and beds. Check the number of gravity trenches with, ponded effluent. Identify <br /> the percentage of the system in use.Determine if action is needed, <br /> • Pressure trenches and beds-Lateral flushing. Check lateral distribution; if cleanouts exist, flush <br /> and clean as needed. <br /> All other components--inspect as listed here: <br /> _q_ <br />
