I have purchased an older home about a year ago. I have had a little septic water seepage near the tank (no slime, just smell and wet ground). When digging up the drain line near the tank to install cleanouts for the drain field lines, I discovered the gravel bed was fine and basically pretty dry. The pipes however are filled with goo plugging the holes in the pipe preventing the water from exiting the pipe. The simple answer for cleaning the lines is a jet wash, but that costs money. Is there a more cost effective solution? I used Roebic K57 down the toilet about a month ago without much improvement. I am planning on having my tank pumped, but want to see if there is anything I should try with the field before pumping since pumping will not solve any problem with the field, but I don't want to pump again in case I have to do something with the field. Is there anything I can pour directly into the drainfield (now I have added cleanouts) to help or could I run a throw-away garden hose with a sprayer down the line? Any suggestions?
