Frequently Asked Questions

Do all septic tanks need to be pumped out?

Yes. Every septic tank will eventually fill with solids and require pumping. Even if water appears to drain well, sludge builds up in the base over time and reduces the system’s capacity.

If not removed, this leads to blockages, backups and potential system failure. Regular cleaning ensures the tank continues to function efficiently and avoids costly repairs.
How do I know if my septic tank is full?

Some tell-tale signs include slow-draining sinks, unpleasant smells and water pooling around the septic area. Gurgling drains or backed-up toilets are also common indicators.

If you’ve gone more than 3–5 years without a cleanout, it’s smart to book an inspection—even if things seem fine on the surface.
How long does a septic tank clean take?

Most septic tank cleanouts take between 30 minutes and an hour. Larger tanks or systems that haven’t been cleaned in years may take longer due to increased sludge or challenging access.

The process involves locating the tank, removing the waste, checking for blockages, and safely securing the system before departure.
Can heavy rain affect septic cleaning?

Yes. Heavy rainfall can saturate the soil around your septic system, making it harder to access or pump. Waterlogged ground can cause lids to shift, tanks to flood and drainage to slow.

It’s best to wait for drier conditions unless you're dealing with an emergency. Always let your provider know if conditions have changed before your booking.
