Frequently Asked Questions About Septic Pumping
FAQs
How often should a septic tank be pumped in Maryland?
Most homes should pump their septic tank every 3 to 5 years, depending on household size and water usage.
What happens if a septic tank is not pumped?
If sludge levels become too high, solids can escape into the drain field and cause system failure or sewage backups.
Can heavy rain affect septic systems?
Yes. Heavy rainfall can saturate the drain field and reduce its ability to absorb wastewater, which increases the risk of backups if the tank is already full.
How do I know when my septic tank was last pumped?
Many homeowners do not know their last pumping date. If you cannot remember the last service visit, it is usually safest to schedule an inspection.

When Should You Schedule Septic Pumping?
If you cannot remember the last time your septic tank was pumped, it may already be overdue.
