The average septic tank should be pumped out every 2-3 years (depending on use and the number of users).
A common argument against this is from homeowners with only 1 or 2 occupants who state that it's barely used and not full at the end of these three years.
While it may not be full, but after a certain amount of time the solids at the bottom, which we pump out, become packed down and can be difficult to vacuum out and cause you to incur additional charges.
We provide septic and holding tank pumping services to clients in the Ottawa area and surrounding regions. If you are unsure we service your area please contact us and we will happily assist you!
