Common questions
Septic Tank Not Draining FAQs
These answers are general guidance. The actual system condition determines the appropriate work.
Should a septic tank ever be empty?
No. An operating tank normally contains liquid. The question is whether flow through the system is normal.
Can a clogged filter cause slow drains?
Yes. An accessible effluent filter is one possible restriction, but other components may also be involved.
Does slow drainage mean the field has failed?
Not automatically. Tank, pipe, filter, pump and loading conditions should be checked before that conclusion.
