A property management company called ASAP Drain Guys & Plumbing because their mainline was backed up and water was coming out of the clean out caps.
ASAP located a clean out in the front yard of one of the units. The tech removed the clean out plug and noticed sitting waste. He then ran the mainline cable through as far as 150 feet several times to clear out the obstruction clogging the drain system. The cable was worked back and forth until the clog was loosened and the standing water level dropped. The cause of the blockage was unknown.
ASAP then ran the hose into the clean out for about 15 minutes about noticed no clogs or other issues. Lastly ASAP cleaned the work area.
