Fix Your Own Septic System Cheap

septic system clogged and overflowing

This is what the inside of my septic tank access hatches looked like when failure became apparent. Eight years later, my system is still working perfectly without professional help

Once upon a time, my 20+ year old septic system failed. The date was June 17, 2011. Sewage was sitting about a foot over the top of the tank. Sometimes it even ran out over the ground. As bad as it was, I wasn’t ready to throw in the towel and have my system rebuilt – too expensive and too disruptive. After multiple unsuccessful attempts to use various products to fix my septic system, I decided to go back to first principles. Bacterial additives weren’t working, and aeration wasn’t working fast enough. I’d tried everything obvious, but didn’t want to give in yet and have my system rebuilt.

After unsuccessfully trying various additives and methods without success, a question occurred to me. “Is there something out there that could deliver the power of a pressure washer to the inside of leaching pipes?” I didn’t know of anything at the time, but I looked anyway. Seek and ye shall find, right?

This is the Clog Hog attachment that goes on the end of a pressure washer wand. This tool is key to successful DIY revival of a failed septic system

The first thing I did was figure out how to physically de-gunk the insides of the leaching pipes in my septic system. As it turns out, this makes all the difference for septic system revival and maintenance. It’s at the heart of the DIY septic system techniques I found worked perfectly for me. The crazy thing is, this kind of cleaning hardly ever happens. The tool that makes it all possible is a long, fairly stiff hose attachment called a Clog Hog. It  clips onto the wand of a pressure washer and delivers blasts of water to the inside walls of pipes as long as 100 feet. The end of the device has four water jets. One points forward to blast out anything blocking the pipe, while the other three point backwards at an angle. These backwards-facing jets propel the hose into the pipe, sort of like little jet engines. In the case of leaching pipes, these side jets also deliver valuable cleaning action along the side of the pipes and through the holes in the leaching pipes.  I’m sure the sideways blasting action  that comes through the holes does a lot to open up the soil and allow more sewage percolation later on.

To work properly for septic system revival, I discovered that the hose attachment needs to be connected to a gas-powered pressure washer that delivers at least 3000 psi of pressure and 3 or 4 gallons per minute of water. Don’t bother with an electric pressure washer or a tiny gas model for jetting out your septic lines. In my experience you need lots of power to do the job.

So how do you get into your leaching pipes to clean them? First, you need to find the ends of each pipe, so I started thinking like a detective with a shovel. A typical household septic system might have four to six leaching pipes extending 40, 50 or 60 feet out from the tank and manifold. If you’re lucky enough to be able to see extra growth of grass along the length of one or more leaching pipes, that makes your detective work easier. Even in my failed system, there were faint traces of extra grass growth along one pipe. I dug down near what I thought was the end of a leaching pipe and crossed my fingers. You’ll probably have to make several attempts before you find any part of your leaching pipes, but don’t give up. Once you’ve discovered the end of one pipe it’ll be easier to find the others. The goal is to remove enough soil to create an open space around the ends of the pipes, extending far enough back that you can cut off the capped end of the pipe. I used a reciprocating saw to cut the plastic pipe end caps off.

I don’t know if jetting alone would have done the trick for reviving my septic system, but I wanted to make sure I did all I could. That’s why I also focussed on improving the percolation rates of soil around leaching pipes. As it turns out, biomat slime on the inside of the pipe and covering the leaching holes is not always the only problem with failed septic systems. Sometimes chemical reactions can occur in the soil over time that prevents full leaching action around the pipes. This is why a few products are made to dissolve impervious layers of soil right around leaching pipes.


After a lot of research, I bought a product called AfterShock. It’s specifically made to improve the percolation rate of soil around leaching pipes and it uses a combination of chemical and microbial treatments to get the job done. Unlike other products that get added to the tank, AfterShock goes only into the leaching pipes themselves, and only after cleaning them out. It comes as a powder that you mix with water then pour into the leaching pipes after you’ve made them squeaky-clean with the pressure washer. You don’t want the AfterShock to have to battle with biomat and slime on the inside of the pipes. It has to get in contact with the impervious layers of soil around the holes in the leaching pipes. That’s its job.

You want to give as much time as possible for AfterShock to work, so you need to have your septic tank pumped out immediately before the treatment. Depending on how much household water you use, this will buy you at least a couple of days of working time without sewage flow – more if you’re frugal. In my case, since there was no distribution box in my system, I put a flexible piece of 1” polyethylene pipe into the outlet of the tank, put a funnel on the end of the pipe, then poured the liquid into the leaching pipes this way. Do this work after you’ve jetted the leaching pipes and after you’ve installed some removable cleanout ports on the ends of the pipes. You don’t want that precious AfterShock liquid to run out of the leaching pipes right away. The longer it stays in contact with the soil around the pipes the better.
