WHAT TO EXPECT DURING A
SEPTIC TANK PUMP-OUT | Septic tanks require pump-outs when the solids that accumulate in the tank begin to reach the tank’s storage capacity. The tank should be pumped when total solid accumulation is between 30% and 50% of the total capacity. You are encouraged to observe the pump-out and to use the checklist below to ensure that all steps are completed. WHAT WILL THE PUMPER DO? Before Pumping __ Note the liquid level of the tank in relation to the tank’s outlet pipe. A liquid level below the outlet pipe usually indicates a tank leak. A liquid level above the outlet pipe can indicate a problem with the pipe to the drainfield or the drainfield itself. Pumping __ Pump the tank from the manhole. Pumping from inspection ports may damage tees and baffles. However, if pumping must occur from inspection ports, be sure to pump from both ports in order to pump all areas of the tank. __ Watch for backflow from the tank outlet pipe. Significant backflow indicates a drainfield system backup. A small amount of backflow can indicate a sag in the pipe to the drainfield. __ Pump the tank thoroughly. Use a septage spoon and backflush to loosen the sludge in the corners of the tank. __ Do not “seed” the tank by leaving septage in it. __ Do not scrub or power wash the tank’s walls. After Pumping __ Check the empty tank and note any signs of structural damage such as an open weep hole, leaking midseam, damaged baffles, or cracks. __ File report with the town if required. Check with your local town hall to find out whether you or the pumper need to provide the report of the completed pump-out. |
