The pump, or what tells it to run?
A pump that will not start may be fine. A float stuck on grease, a tripped overload, a failed relay, or a power problem stops it just as surely, so the controls are tested before a pump is pulled.

Your options
Finding why a lift station failed
A pump replaced for the wrong reason fails again. These questions come first.
What the wet well shows
A grease mat, wipes and rags, or settled grit points to a cleaning and source-control problem. Pumping out and cleaning the well can be part of the repair, not a separate job.
How much the station has to carry
A duplex station where one pump now does all the work has lost its backup. Age, parts availability, alarm history, and what an overflow would cost decide between repairing and replacing a pump.
Around the Valley
Plan for monsoon outages before summer
A lift station without power cannot pump, and summer storms in the Valley can knock power out. Know whether the alarm still works during an outage, who receives it, how much storage the wet well has, and whether the station has a generator connection, before the season starts.
Planning the work
What affects the price
- Pump type, size, and how deep it sits in the wet well
- Whether the wet well has to be pumped down before work
- Float, control, and alarm parts
- Check valve, rail, and discharge piping condition
- Number of stations and the visit frequency in a maintenance plan
When the lift station alarm goes off
A high-level alarm means wastewater is rising in the wet well faster than the pumps remove it, or the pumps have stopped. What happens next depends on how much storage is left, so act right away and call. Emergency service for lift station alarms is available 24/7, including nights, weekends, and holidays.
- Ask everyone the station serves to stop running water: no laundry, dishwashers, or showers.
- Keep people away from the wet well, its hatch, and the control panel. Never enter a wet well.
- Note which lights are on at the panel and whether either pump is running, but do not keep resetting breakers.
- Do not silence the alarm and walk away. Call 480-663-2255 with the station's location and what the panel shows.
What scheduled lift station maintenance covers
A maintenance visit checks every part that can stop the station, and leaves a record the next technician can read.
- Run each pump and confirm the pumps alternate
- Test each float and the high-level alarm
- Look for grease, rags, and grit building up in the wet well and on the floats
- Check that the check valves hold and the discharge does not drain back
- Record run hours or cycle counts where the panel shows them
- Schedule wet-well pump-out and cleaning when buildup calls for it
Wet-well pump-out and cleaning
Grease, wipes, and settled solids in the wet well foul floats and wear out pumps. The One Call team pumps out and cleans wet wells with its septic pump trucks, so the cleaning and the pump and float work can be planned as one visit and one record.
Stations that serve restaurants or heavy-use restrooms may need cleaning more often than ones that serve offices. The interval is set from what each visit finds.

Common questions
Lift station repair and maintenance questions
Do you offer 24/7 lift station emergency service?
Yes. Emergency service for lift station alarms and failed pumps is available 24/7, including nights, weekends, and holidays, and same-day emergency service is available. Call 480-663-2255 with the station's location and what the control panel shows.
What should I do when the alarm sounds?
Reduce wastewater use, keep people away from the wet well and electrical equipment, and call for service. Do not silence an alarm without determining the cause.
How often should a lift station be maintained?
Usage, solids and grease load, redundancy, equipment age, alarm history, and the cost of failure all matter. Critical stations often need a structured monthly or quarterly program.
Can you pump out and clean the wet well?
Yes. The One Call team pumps out and cleans wet wells with its septic pump trucks, and the cleaning can be scheduled together with pump and float maintenance.
Why does my lift station pump keep running?
A float stuck in the on position, a check valve letting water drain back, a worn impeller, a clogged intake, or more inflow than the pump can handle. Each has a different fix, so the cause is found before parts are replaced.
