6 Years Since Emptying – Tanker Driver Very Impressed

I just had my 3000 litre plastic septic tank emptied after 6 years. I have been using Muck Munchers XL since the tank was installed, some 16 years ago, and this is the second time it has been emptied. On both occasions, there was so little sludge in the tank it could have gone another 6 years. Even the tanker driver, commented that people who use your products have negligible problems and long intervals between pumping out.
