Pump Station Float Switch Faults support is handled around the actual pump station arrangement: chamber type, pumped material, pump duty, controls, alarms, valves, rising main, access, ground conditions and whether the work is repair, servicing, refurbishment, replacement or new installation.
Likely causes
Float switches and level controls are common failure points in sewage pump stations because they work in a harsh environment. The diagnosis should separate pump faults from control faults, chamber faults and discharge pipework problems. A structured check avoids replacing a pump when the real issue is a float, valve, panel or rising main fault.
- tangled or fouled floats
- pumps not starting
- pumps not stopping
- high level alarm float faults
- incorrect float spacing
- replacement level control options
What to do first
Keep clear of chambers, wet electrical equipment and live control panels. Do not enter a confined space. Reduce water use where possible if the chamber level is rising, then send photos of the control panel, chamber, pumps, alarm display and any visible labels. For urgent loss of service, call the pump station engineers directly.
What Alton Pumps can check
Our engineers can review the pumps, float switches, control panel, valves, guide rails, non-return valves, discharge pipework, chamber condition and rising main symptoms before advising on repair, refurbishment or replacement.
