For optimum system performance, we recommend our specially blended septic tank formula that’s designed to improve and maintain septic tank and cesspool performance.

One kit contains a year's supply of treatment.

What size tank do you have?

Most residential septic tanks are approximately 1,000 gallons. Tanks are known to be as small as 500 gallons or as large as 1,500 gallons. We service any size tank no matter how big or how small.


Tanks need to be well maintained to operate at their best. They require inspection every 1-3 years, depending on which region you’re in.

Typically, we recommend servicing tanks every 3-5 years. They will need to be serviced more frequently for certain types of soaps (liquid soaps are harder on septic systems than powder). Also, any medical conditions and the types of paper products discharged through your system will impact the frequency of service.

Also, if your home remains vacant for more than six months, septic problems can arise and an inspection is recommended.
