- Pump up to 1000 gallons (additional cost per 100 gallons) - Agitate solids into a liquid sludge scraping the bottom until clean as possible. Upon arrival I spoke with the homeowner and she made me aware that a smell was coming from her drains and previous plumbers told her that it was her septic tank. After locating and diagnosing the issues of the septic tank I noticed it needed to be pumped. I gave her multiple upfront options and she decided upon option 1. After signature approval I began pumping and noticed water coming back from the drain field, so I recommended our sewer specialist come and check it out. I then agitated the septic tank until all solids were turned into a liquid sludge and continued pumping. Upon completion I cleaned up all tools and materials.
