Yes,
I have to hire the septic plumber to dig up the D Box and install the riser. Then he will blast out the laterals with his high pressure hose and his truck will suck out the water & sludge just like he was draining the septic tank. His high pressure pump is far more powerful than mine. When he is done, I can do it myself with my own pressure pump and my Clog Hog the next time. The plumber will then dump a 50 gallon barrel of hydrogen peroxide into the D-Box.
I am still pouring Lime-Sulfur (septic seep) into the D-Box. This is going very slow, because the field is so clogged up. My fingers are crossed in hopes this works one more time.
