Solve septic system problems

  The #1 cause of septic system failure occurs in the drain field.

Drayner's Septic Seep

We no longer carry Septic Seep. 
SEPTIC SEEP, a calcium polysulfide based product, was invented in 1953 by soil and wastewater experts in the labs of Chevron-ORTHO.

Septic Perc Eco-friendly soil restoration

Septic Perc ® was invented in 2012 by soil and wastewater experts familiar with the production of the former product. Septic Perc has an Eco-friendly formula designed for the 21st century.


In the lab and in the field it has been demonstrated to work as effectively as the old fashioned calcium polysulfide products. It restores drainage to septic system soil - even in clay.

A Most Important Testimonial From a Pro

PSTS used a well-known calcium polysulfide product for over thirty years to treat septic drain field soil that stopped percolating. It didn’t always work, but it usually did saving our customers thousands of dollars by rejuvenating the soil rather than replacing the drain field.


In 2014 we started experimenting with Septic Perc as a possible replacement for the old product. Our technicians preferred the pleasant odor and the idea that this is an eco-friendly product. It also comes with fewer health warnings, so it’s safer for users, our employees.

In 2016, after two years of using both products we decided to switch to the newer product Septic Perc.  It performs at least as well as the old product without the rotten egg smell. The response from our customers has been overwhelmingly positive as they learn about the new eco-friendly product we are using to treat their drain fields.
