Annual maintenance and warranty

Annual maintenance program for Ecoflo septic system and septic tank

A trusted service for your peace of mind!

Certain local regulations oblige the owner of an advanced secondary treatment system to have a binding contract with the system manufacturer, the manufacturer's representative or a qualified third party in which it is stipulated that minimum annual maintenance will be performed on the system. Please consult your municipality to know the applicable regulations on wastewater treatment systems and/or your obligations in respect to your Ecoflo Biofilter.

Premier Tech Aqua has developed and put in place a unique network of local partners comprised of wastewater treatment professionals. Trained and certified by PTA on a yearly basis, these qualified professionals offer an outstanding preventive service. To date, they carried out more than 360,000 annual inspections and close to 12,000 filtering media replacements. With our network of service partners – now known as WALTER – you benefit from an unparalleled technical support and true peace of mind.

Annual maintenance

Carried out by a WALTER service partner, the annual visit, which may be required as per certain local regulations, consists of a 15-point inspection that notably includes:

  • Inspection of the Ecoflo filtering media and internal components
  • Inspection of the tipping bucket and distribution plates (distribution system)
  • Removal of all particles that could affect proper operation of the Ecoflo
  • Scarification of the filtering media on its whole surface to ensure adequate wastewater infiltration
  • Photos (filtering media and discharge area)
  • Verification that the treated water is properly discharged (Ecoflo with bottom)
  • Entry of information in the database

A proof of maintenance is left on the door handle after each annual visit. We recommend you to keep it with your Ecoflo owner’s manual.


The Ecoflo Biofilter is sold with a 10-year warranty forthe shell, an 8 or 10-year warranty (depending on the installation year and model and if the septic tank is equipped with an effluent filter) for the filtering media and a 2-year parts and 1 years labor warranty for the pump, floats and alarm box if the system is equipped with a pumping station.

Once the filtering media has been replaced by a qualified service partner, the Ecoflo Biofilter will perform as new the warranty protecting the performances of the filtering media is renewed for the initial period of 8 or 10 years (depending on the installation year, the model and if the septic tank is equipped with an effluent filter).
