Is Your Pump Station Failing? Warning Signs to Watch For

At Paverose Environmental, we provide specialist pump station repairs and maintenance for sewage, surface water, and effluent pumping systems. From a tripped high-level alarm to a complete motor burnout, our engineers have the expertise to restore your system to full operation.

Pump station problems rarely announce themselves conveniently. Often, the first sign is a crisis. But if you know what to look for, you can catch issues before they escalate into emergencies.

Check These Warning Signs

  • High-level alarm or beacon is active — this means the pump isn’t keeping up with the inflow and the wet well is approaching overflow
  • Foul odours or visible effluent around the wet well — indicates the chamber may be overflowing or the system is backing up
  • Unusual noises — grinding, banging, rattling, or constant running suggests mechanical problems, blockages, or bearing failure
  • Slow drainage from connected fixtures — toilets, sinks, and showers draining slowly or gurgling indicate the pump isn’t clearing waste effectively
  • Pump running continuously without emptying — could mean a blocked impeller, failed non-return valve, or undersized pump
  • Pump not starting when levels rise — likely a float switch fault, electrical issue, or motor failure
  • Unexplained increase in electricity bills — a pump working harder than it should due to partial blockages or mechanical wear

The Regulatory Risk

A failed pump station isn’t just an inconvenience—it’s a potential environmental incident. Unauthorised discharges of untreated sewage can result in significant penalties under environmental legislation. If your pump station serves multiple properties or commercial premises, the reputational and financial consequences of a failure can be severe. Don’t wait for an overflow to take action.

Proactive Servicing to Prevent Crisis

Emergency repairs are expensive and disruptive. Planned preventative maintenance (PPM) catches problems before they become failures—and costs a fraction of an emergency call-out.

What's Included in a Pump Station Service

Our routine maintenance visits cover both mechanical and electrical systems:

  • Wet well cleaning — removing accumulated sludge, FOG, and debris that increases pump workload and causes blockages
  • Pump inspection and testing — checking impellers, seals, bearings, and motor windings for wear
  • Float switch and sensor cleaning — removing grease buildup that prevents proper operation
  • Control panel inspection — checking connections, testing relays, and verifying alarm functionality
  • Non-return valve testing — confirming valves seal properly and aren’t allowing backflow
  • Electrical safety checks — testing insulation, earthing, and overall electrical integrity
  • Performance recording — documenting pump run times, cycle frequency, and any developing issues

 

For most domestic and light commercial stations, we recommend servicing every 6-12 months. High-usage systems (multi-occupancy buildings, commercial kitchens, industrial sites) may need quarterly visits.

Mechanical & Electrical Pump Restoration

Unlike general drainage contractors, we handle both the “wet” side and the electrical side of pump station repairs. Our engineers diagnose and fix mechanical faults, electrical failures, and control system problems—giving you a complete repair service from a single provider.

Submersible Pump Repairs

Submersible sewage pumps take a beating. They’re submerged in corrosive wastewater, handling everything from human waste to the things people shouldn’t flush (wet wipes, we’re looking at you). Common repairs include:

  • Clearing blockages — removing rags, wipes, sanitary products, and FOG (fats, oils, grease) that have clogged the impeller or volute
  • Impeller replacement — worn or damaged impellers reduce pumping efficiency and can cause the motor to overwork
  • Seal replacement — failed mechanical seals allow water into the motor housing, leading to bearing failure and burnout

Control Panel & Electrical Fault

The control panel is the brain of your pump station. When it fails, nothing works properly—even if the pumps themselves are fine. We diagnose and repair:

  • Failed capacitors, contactors, and relays — common causes of pumps not starting or running intermittently
  • Wiring faults and loose connections — corrosion and vibration can degrade electrical connections over time
  • Circuit breaker trips and fuse failures — often symptoms of underlying issues like motor overload or short circuits
  • Alarm system faults — ensuring high-level and fault alarms function correctly to warn you before problems escalate
  • Control logic errors — reprogramming duty/standby sequences, adjusting pump cycling, and correcting timing issues

Float Switch & Level Sensor Replacement

Float switches are often the most common failure point in pump stations. They’re constantly submerged in sewage, getting coated in grease and debris that prevents them moving freely. When floats stick or fail, pumps either run continuously (burning out the motor) or don’t run at all (causing overflow).

We replace faulty floats and level sensors, calibrate them correctly for your wet well dimensions, and ensure the high-level alarm triggers at the right point to give you warning before overflow occurs.

Pipework & Valve Repair

It’s not always the pump that’s the problem. Failed pipework and valves can cause symptoms that look like pump failure:

  • Non-return valve (NRV) failure — allows pumped sewage to flow back into the wet well, meaning the pump has to work constantly to re-pump the same liquid
  • Gate valve and isolation valve replacement — essential for maintenance access and emergency shutoff
  • Rising main repairs — leaks, blockages, or damage to the discharge pipework
  • Inlet pipework blockages — sometimes the problem is upstream, not in the pump station itself

FAQ

Frequently Asked Questions

How quickly can you attend a pump station failure?

For emergency call-outs, we aim to have an engineer on site within hours, not days. Response times depend on your location and current workload, but we prioritise pump station failures because of the environmental and operational risks involved. When you call, we’ll give you an honest assessment of when we can reach you.

A high-level alarm means the liquid level in your wet well has risen to a critical point—the pump isn’t keeping up with the inflow. This could be due to a pump failure, blocked impeller, faulty float switch, electrical fault, or a blockage in the rising main. It’s a warning that overflow is imminent if the problem isn’t resolved. Don’t ignore it. Call us immediately so we can diagnose and fix the issue before it becomes an environmental incident.

Yes. We work on all major manufacturers including Grundfos, Xylem/Flygt, Tsurumi, KSB, Jung Pumpen, Lowara, DAB, and many others. If your pump is from a less common manufacturer, let us know when you call and we’ll confirm we can source any required parts.

Absolutely. We often combine pump repairs with wet well cleaning using a vacuum tanker. Removing accumulated sludge, grease, and debris reduces the load on your pumps and helps prevent future blockages. For many repairs, cleaning the wet well first is essential to properly access and inspect the pumps.

For domestic and light commercial stations, annual or six-monthly servicing is typically sufficient. High-usage systems—multi-occupancy buildings, commercial kitchens, industrial sites—should be serviced quarterly or even monthly depending on loading. We’ll assess your system and recommend an appropriate schedule based on its usage and condition.

It depends on the pump’s age, the nature of the fault, and the cost of repair versus replacement. Simple issues like float switches, seals, or cleared blockages are usually worth repairing. If the motor has failed on an older pump, replacement is often more cost-effective. Our engineers will give you an honest assessment and won’t recommend replacement unless it genuinely makes sense.
