septic records.
Then the problem.
Before anyone talks about pumping, repair or replacement, locate the available records, map the actual system and define the property decision in front of you.

Look from the surface. Never open or enter a septic tank. Do not excavate or drive over an unknown system area.

Lens 01 / property file
Map the evidence before the equipment.
Gather permits, filings, plans, service history, past assessments, renovation information and known component locations. Record gaps rather than guessing.

A record search may help identify the original system, authorized-person documentation, filing history and locations worth verifying in the field. It can also expose what is not known.

A warning sign
is a question.
Not a verdict.
Slow drainage, unusual sounds, sewage odours, backups, wet or unusually lush areas and surface discharge deserve prompt attention—but they do not establish the cause from a distance.

not the method.
Pumping equipment, excavation, assessment and system design are not interchangeable roles. The right route depends on the actual system, property and project decision.

and edge conditions.
Properties around Chemainus, Crofton, Maple Bay, Cowichan Bay, Duncan and nearby rural areas can differ in jurisdiction, records, terrain, access and system type. Location words are context—not a claim that every property follows the same process or is covered by one provider.

ground opens.
How often should a septic tank be pumped?＋
There is no responsible universal interval for every property. The system type, tank, use, household, operating history and current professional guidance matter. Ask what evidence will inform a property-specific maintenance plan.
Does a slow drain mean the septic system has failed?＋
Not necessarily. Slow drainage is a signal worth documenting, not a remote diagnosis. Location, timing, other fixtures, recent use, weather and visible surface conditions can help frame the appropriate investigation.
Can I open the tank to check it?＋
No. Never open or enter a septic tank yourself. Tanks can present fall, gas, exposure and structural hazards. Keep people away and use an appropriate professional route.
What should a septic inspection for a property sale include?＋
Ask for the exact records reviewed, components accessed, observations made, limitations, photographs or mapping, and the written output. Avoid treating an undefined “pass” as a design or capacity conclusion.
Who plans a repair or replacement system?＋
BC requirements assign specific work to authorized persons and require applicable filings and records. Confirm the current role, authority route and documentation for the property and proposed work.
Can an old system support a renovation or added bedrooms?＋
That cannot be concluded from age, a photo or pumping history alone. Define the proposed change, collect the existing system file and route design, capacity and filing questions appropriately.
