Frequently Asked Questions

Why do drainfields fail?

Most drain field failures occur when septic tanks are not maintained properly or have lost their baffles due to H2S gas corrosion. The end result of this scenario is that scum, sludge or even suspended bio-solids find their way into your drain field and form a layer called "biomat" in the soil that is located on the perimeter of your drain field.


​This biomat layer seals the soil and prevents the water (referred to as effluent) exiting your tank, from percolating into the soil. When the effluent can’t percolate into the soil, hydraulic pressure develops and the effluent is forced upward where it shows up on the ground and will puddle, pool, or sometimes just show up as very green well fed vegetation. Eventually, this condition can manifest itself as a “plugged drain/sewer” and you won’t be able to use your toilets. Sewage may even back up into the house through standpipes or leaking through wax rings or toilet flanges.

What are the signs of a failing drain field?

Slow moving drain and/or gurgling sounds coming from your drains

Sewage smell coming from septic tank/drain field area or inside drains

Water backing up into toilets, drains, dish or clothes washers, etc.

Water near or around septic tank

Standing water on top of drain field

Water coming back into your septic tank after being pumped

When your septic tank is "riding under pressure". Which means there is water above the operating level indicating that your tank is under pressure because your drain field is not dispersing the effluent as it should.

Why can a drain field not be restored year round?

  • A drain field restoration can only take place when the ground is not frozen and the air temperature is above 32 degrees.  There are three main reasons for this:

  • When using compressed air it will freeze if the temperature drops below freezing.  

  • If the ground is frozen the probes are not able to fully penetrate the soil in order to create the fissures.

  • When there is snow on the ground, it is difficult to see the holes that were created by the probe and therefore we are not able to apply the necessary biology to complete the process. 


Does the restoration process work on every system?

Not always. Though the process will work on approximately 90-95% of failed or failing systems; there are other reasons not related to biomat that can cause systems to fail. Increased hydraulic loading (excess water being put into your drain field), addition of water softeners or over loading the system with additional fixtures, improper initial installation, under sizing, surface compaction (driving vehicles or equipment over the field), etc. This is why we offer our Good Money Guarantee so that you never waste money if the restoration does not work on your system.
