Identify the Fault
Check covers, seals, tees, filters and pumps. Symptoms alone do not show which part failed.
Check Water Entry
Compare tank levels with rainfall and household use. Groundwater entering the tank can add unwanted flow.
Repair or Replace
Small component faults may be repairable. A damaged shell or unsafe cover needs a different scope.
Get the Right Approval
Use the Coastal Health District repair/addition application and confirm county requirements before excavation.
