Septic Tank Maintenance Advice and Best Practices
Routine septic tank maintenance is the key to keeping your system in good working order. For most homes, we recommend a full pump-out and clean every four years. However, larger households or high-use systems may need more frequent servicing.
If you notice strong odours coming from the tank area or slow drainage from your sinks, showers or toilets, it could be a sign that your tank is full. Getting your tank cleaned promptly helps prevent overflow, backups and damage to your soakage trenches. Regular maintenance also extends the life of your septic system, saving you money in the long run.

Signs Your Septic Tank Needs Cleaning
Keep an eye out for common warning signs such as unpleasant smells, gurgling sounds in pipes, wet patches in your yard, or slow-draining fixtures. These are clear indicators your septic tank may need professional attention.

Septic Tank Cleaning FAQs
How often should I have my septic tank cleaned?
Most households should schedule a full septic clean every three to four years. However, if your household is larger, or if your system is used heavily, you may need more frequent pump-outs to prevent build-up and overflow.
What happens if I don’t clean my septic tank regularly?
Without regular cleaning, solid waste can accumulate and clog your system, leading to unpleasant smells, backups and potential damage to your soakage area. Regular maintenance helps prevent these costly problems.
