know when to
pump your tank
Routine maintenance recommended
Time for a pumping
Septic systems are extremely effective in breaking down waste but eventually sludge and scum begin to accumulate. If sludge builds to the height of the outlet baffle it could flow into the second chamber and disperse to the drain line, clogging the system. Therefore, when sludge and scum equal 35 percent of the tank volume, it’s time for a pumping.
Pumping is necessary, regardless of percentage of sludge/scum, when evaluating an existing system. A complete system evaluation requires inspecting baffles for damage and/or wear and tear. Also, pumping allows the inspector to check inside the tank to check walls for cracks or damage.
