One component failed
A pump, float, baffle, lid, effluent filter, or section of line can be repaired or replaced on its own once it is confirmed as the cause.

Your options
Repair the part or replace the system?
A backup or alarm does not automatically mean a new system. What failed decides the scope of the repair.
The tank or the drain field failed
Replacing either one is an alteration in Maricopa County, so the repair is planned around the county permit and its inspection.
Both have failed
When the tank and the disposal field have both failed, the county requires a new onsite system. That becomes an installation project with its own design and permit.

Repairs that need a county permit
Maricopa County Environmental Services requires an Alteration permit to replace a failed septic tank or a failed disposal field, and a new system when both have failed. The county issues a Construction Authorization before the work and approves it with a Discharge Authorization or a white tag authorizing backfill. For property in Pinal or Yavapai County, check that county's process.
Planning the work
What affects the price
- Which component failed and how deep it is buried
- Whether the tank has to be pumped before the repair can start
- Replacement parts such as pumps, floats, and controls
- Whether a county permit and inspection apply
- Equipment access to the tank or field
Pump, float, and alarm problems
Some systems move effluent with a pump. Maricopa County describes alternative systems that use pumps or gravity to pass tank effluent through sand, peat, or other media, and the EPA recommends that systems with electrical float switches, pumps, or mechanical parts be inspected more often, generally once a year.
When a pump or high-water alarm sounds, cut water use to the minimum and request service, and leave the control panel and wiring alone. On the visit we work through the likely causes in order:
- Power to the pump and the control panel
- Float position and whether the float switch responds
- Whether the pump runs and moves effluent
- The liquid level in the tank or pump chamber
- The effluent filter and the line leaving the pump

Common questions
Before you schedule
Does every septic problem require replacement?
No. Clogs, broken components, controls, pumps, filters, lids, and piping can be repaired on their own. In Maricopa County, replacing a failed tank or a failed disposal field takes an Alteration permit; when both have failed, the county requires a new system.
Will pumping fix a failing system?
Pumping can provide temporary relief and is part of maintenance, but it does not repair a failed pump, damaged pipe, saturated field, or structural problem.
How soon can you look at a septic problem?
Same-day service is often available for septic repairs, depending on the job. A backup, overflow, or alarm that is happening now is an emergency, and emergency septic service is available 24/7.
What does a septic alarm mean?
An alarm on a septic control panel signals that the liquid level is higher than it should be or that a pump is not running as expected. It does not say which part failed, so the pump, float, controls, and power all need checking before the level rises further.
How do you tell a septic problem from a plumbing problem?
We separate the two before recommending a repair. A clog in the building drain between the house and the tank is a plumbing repair; a failed baffle, pump, or drain field is a septic repair. If the cause is the building drain or a city sewer connection, One Call Plumbing handles that work.
