Before pouring a gallon of chemical-filled Draino down the drain—remember your septic system. You may be fixing the clog, but you could be killing the bacteria needed to keep your system healthy. Luckily, modern technology has invented new and different solutions for those pesky clogged drains. But, is hydro jetting safe for your septic system?

Is Hydro Jetting Safe for Your Septic?What is Hydro Jetting?

No chemicals and no abrasive materials. Just pure water—with a lot of force. Hydro Jetting eliminates clogs by blasting water down a pressurized hose. The water comes out with a force of 3,000-4,500 psi, eliminating the clog apart.

The Pros of Hydro Jetting

Let’s start with the good news.

Less Abrasive to the Inside of Pipes

Compared it its metal counterparts, hydro jetting is less abrasive to the inside of your plumbing. Instead of metal rods and sharp hooks blindly working their way to the clog, you have a soft-sided hose and water.

Gets All of the Clog—Including the Roots

Clogs have roots. Think of all the hair going down your shower drain holding on to the sides of the pipe for all that it has. While snakes and other methods can get the bulk of clogs or blast a large enough hole to allow normal functions, they do not get everything. Hydro jetting does. It even goes above and beyond, blasting bacteria and smells from your pipes.


Hydro Jetting comes in different sized hoses, is soft and pliable, and can reach hard to get to places. This includes clogs in the header line, the line connecting your septic tank to the drainfield.

If regular maintenance and pumping haven’t occurred, sewage can backup up into the header line. Designed to expel treated liquid sewage, the header line cannot handle solids. In the past, this would have been a costly repair which required the deconstruction of the line to clean and possibly replace. Now, hydro jetting can eliminate the clog and eliminate a costly repair.

The Cons of Hydro Jetting

With that force of water, it is no surprise that hydro jetting can also do some damage to your system.

Clay Pipes

While an admittedly older design, if you have clay pipes do not use hydro jetting as clog or blockage solution. The force of the water erodes the soft, clay walls of the pipes.


The delicate drainfield with its perforated pipes is not a place for hydro jetting. The blast of water can force the solid clog through the perforations and into the surrounding gravel or earth. This inhibits the system from properly working.

In addition, a solid waste clog is not treated wastewater. That is now contaminating your yard and eventually the groundwater. The delicate pipes can also be damaged, requiring replacement.

It is Not a Problem Fixer

If you are experiencing clogs, especially clogs in the header line—it is a sign of a more serious, underlying problem. While hydro jetting can completely blast the clog, it does not fix the problem. Depending on the issue, it may be worth it to save the money and fix the problem instead.

Hydro Jetting has some great benefits—and a few significant cons. It all comes down to your pipes and where the clog is. Remember: most clogs and blockages are preventable. Regular proper maintenance and treating your septic system with care are the best ways to rid your systems of clogs.
