Which Package Is Best Value?

Compared with buying single boxes at $69:

  • 12-month supply: $118 instead of $138 — save $20, plus free shipping.
  • 18-month supply: $147 instead of $207 — save $60, plus free shipping.

Our buying advice: Remember that the first box includes your 3-tablet starting dose. If you plan to use Septifix for at least a year, the 18-month package gives the lowest cost per tablet. If you just want to try it, start with one box and use the 60-day guarantee window to judge it.

Septifix Yearly Cost vs. Pumping

At one tablet a month, a year of Septifix costs about $98 (on the 18-month package) to $138 (buying single boxes). That's on top of — not instead of — regular professional pumping. The EPA recommends inspection at least every three years and pumping as recommended, typically every three to five years. Pumping prices vary by area and tank size. See Septifix vs. septic pumping.
