What’s the difference between a simplex and duplex sump pump panel?

A simplex panel runs a single pump. A duplex panel controls two pumps, alternating which one leads on each cycle and automatically bringing in the second pump if the water level keeps rising, so one pump failure doesn’t mean a flooded sump.

Can the alarm be connected to a building monitoring system?

Yes, we can wire the high-water and pump-overload alarm outputs to a building management system, a monitored alarm panel, or a standalone audible/visual alarm, depending on what your property already has in place.

Do you install sump pump panels in parking garages and elevator pits?

Yes, duplex sump pump control panels are common in elevator pits, underground parking garages, and mechanical rooms, and we size and wire the panel to the specific pumps and pit conditions in each location.

Can you replace an existing single-pump setup with a duplex panel?

Yes, we regularly upgrade properties from a single float-switch pump to a proper duplex panel with alternation, alarms, and Hand-Off-Auto control, without needing to replace the pit itself in most cases.

Is a permit required for sump pump panel installation?

In most cases yes, particularly for panels tied to a dedicated circuit or building alarm system. We handle the ESA permit and inspection as part of the installation where one is required.

How much does a duplex sump pump panel cost?

Cost depends on the pumps’ horsepower and voltage, whether it’s simplex or duplex, and whether the alarm needs to integrate with a monitoring system. We provide a clear quote after reviewing your pit and pump specifications.

Sump Pump Panel Installation

Duplex sump pump control panel installation and wiring for industrial, commercial and multi-residential properties, with alarms and redundant pump control.

Overview

A single float switch isn’t enough protection for a mechanical room, parking garage, or elevator pit where a flooded sump means real property damage and downtime. We install and wire duplex sump pump control panels: two pumps alternating lead and lag duty, Hand-Off-Auto selector switches for manual override, high-water alarm and pump-overload indicator lights, and a lockable main disconnect, all wired and tested under load before we leave. Electrovoltage installs sump pump control panels for industrial facilities, commercial buildings, and multi-residential properties across Toronto and the GTA, whether you’re replacing a failed single-pump setup or wiring a newly installed duplex system.

Why It Matters

A basic float switch turns one pump on and off; it doesn’t tell you when a pump has failed, doesn’t alternate between two pumps to even out wear, and gives no warning before water actually reaches a critical level. A proper duplex control panel changes that: it alternates lead/lag duty between two pumps so neither carries the full load alone, trips a visible (and where wired, remote) alarm if the water level climbs past where it should, and flags an individual pump overload before it becomes a full failure. That distinction matters most in the buildings where a flooded sump is genuinely expensive: elevator pits, underground parking garages, mechanical rooms near switchgear or standby generators, and multi-residential buildings where a backed-up sump means an overnight emergency call instead of a caught alarm during business hours. Hand-Off-Auto switches at the panel also let facilities staff manually run or isolate a pump for testing or maintenance without touching the wiring.

How Sump Pump Panel Installation Works

1
Site & pump assessment
We review your existing sump setup, or new pump specifications, pit depth, and alarm requirements to confirm the right panel sizing.
2
Panel selection & circuit planning
We size the duplex control panel, breakers, and dedicated circuit to your pumps’ horsepower and voltage, and plan alarm wiring to a monitored point if required.
3
Installation & wiring
We mount the panel and wire the pumps, float switches, alarm, and main disconnect, then configure lead/lag alternation and every Hand-Off-Auto setting.
4
Load testing & documentation
We test both pumps under load, confirm alternation and alarm function, and provide ESA inspection documentation where the installation requires a permit.

What Affects the Cost

Cost depends on the panel’s pump horsepower and voltage rating, whether it’s a simplex or duplex (two-pump) configuration, how far the panel is from the pumps and your existing electrical service, and whether the alarm output needs to tie into a building monitoring or BMS system.
