The basics

What does a control panel do?

The control panel is the brain of your pump station. It reads the floats, switches the pumps on and off, swaps them over between runs and sets off the alarm if something goes wrong.

Control panel faults often show up as a pump problem, so see pump station repairs, or keep both in good order with regular pump station servicing.

We do this work across Surrey, West Sussex, East Sussex, Kent, Hampshire and London, with tankers and engineers in each area most days.

When a panel fails, a perfectly good pump can sit there doing nothing while the level rises. That’s why the panel is checked on every service, and why a fault needs fixing quickly.

Inside the panel

Getting to know your control panel

Every panel is different, but most twin pump panels have these parts. Hover over or tap the numbers to see what each one does.

  3. 3Run and fault lampsShow which pump is running, and light up if a pump trips or fails.

  5. 5Hours-run metersRecord how long each pump has run. Uneven hours can point to a problem.

  8. 8Cable entriesWhere the pump, float and power cables come in. Water getting in here causes faults.

What we do

Servicing, repairs and new panels

Servicing

Testing lamps, switches, meters, alarms and wiring, and checking for water, heat damage or loose connections.

Fault-finding and repairs

Replacing failed relays, contactors, breakers, boards and float inputs, day or night.

New and replacement panels

Panels to suit your pumps and power supply, installed, commissioned and handed over with documentation.

Alarm and telemetry upgrades

Adding beacons, louder buzzers or remote alerts to an older panel.

Warning signs

What happens when a control panel fails?

A failed panel can stop the pumps starting, stop them switching off, or stop the alarm working, which is the worst of all, because nothing tells you the level is rising.

In a foul pump station, that means waste backing up into the property or garden. In a surface water station, it can mean flooding in heavy rain.

Signs of a panel problem

  • Alarms sounding when they shouldn’t, or not when they should
  • Pumps running constantly, or not at all
  • Fault lamps lit or breakers tripping
  • Unexpected power loss or resets
  • Water, condensation or a burning smell inside

Questions answered

Control panel FAQs

What does ‘hand, off, auto’ mean?

Auto is normal running, where the floats control the pumps. Hand runs a pump manually for testing, and Off stops it. Leave it on Auto unless an engineer tells you otherwise, as running a pump dry in Hand can damage it.

Can I just reset the alarm?

You can mute the buzzer, but the fault that caused the alarm is still there. Call us so we can find out why it went off.

My panel keeps tripping. What causes that?

Often a pump fault, water getting into the panel or a failing component. It needs an engineer to find the cause, as repeatedly resetting it can do more damage.

Can you replace an old panel?

Yes. We supply and install panels to suit your pumps and power supply, and commission them fully.

Can you add remote alerts?

Yes. We can add alarm and telemetry options so you’re told about a problem even when you’re not there.
