help protect your basement

A sump pump helps reduce the risk of basement flooding by moving water away from your home before it can build up and cause damage. Heavy rainfall and unpredictable weather can put basements at risk, which is why many homes benefit from having a sump pump system in place.

  • Helps reduce basement water buildup
  • Supports flood prevention during heavy rain
  • Helps protect your home from water damage

  • Foundation Maintenance
    Repair cracks in the foundation where water may enter.

     

  • Roof Leak Repairs

How Sump Pump Installation Works

Our plumbing team walks you through the sump pump installation process before work begins, so you understand what is involved and what to expect.

Pit Preparation

If there is no existing sump pump, a sump pit may need to be created in the basement floor to hold the basin and collect groundwater.

Drainage
Setup

Drainage around the foundation helps direct collected water toward the sump basin.

Pump Installation

The sump pump is installed into the basin and connected to the discharge line.

Discharge Routing

A discharge pipe is installed to move water safely away from the home.

Testing

The system is tested to help ensure it activates and drains properly.

Transparent pricing and clear communication are key factors when choosing a plumber in Ontario.

What Makes Up a Sump Pump System?

Understanding the basic parts of a sump pump system can help homeowners better understand how the system works and why each part matters.

  • Basement Wall
    Supports the basement structure around the sump system.
  • Access Cover
    Covers the sump opening and helps keep debris out.
  • Check Valve
    Stops discharged water from flowing back into the pit.
  • Sump Pump
    Pumps collected water out of the sump tank.
  • Exterior Discharge Pipe
    Carries water away from the home outside.
  • Foundation Drain
    Directs groundwater toward the sump system.
  • Float Switch
    Turns the pump on when water rises.
  • Sump Pump Tank
    Collects water before it is pumped out.

Transparent pricing and clear communication are key factors when choosing a plumber in Ontario.

choosing the right sump pump

Submersible Pumps

Submersible pumps sit inside the basin and combine the motor and pump into one unit. They are often quieter, save space, and are commonly chosen for homes with stronger flooding concerns.

Pedestal Pumps

Pedestal pumps keep the motor above the basin and use a separate pump below. They are often easier to access for maintenance, but they take up more space and can be louder.

backup protection option

Battery Backup

A battery backup sump pump can continue working during a power outage, which can be especially important during storms.

Water-Powered Backup

A water-powered backup uses water pressure to help clear the basin, but this option may increase water usage and may not be allowed in every city.

Transparent pricing and clear communication are key factors when choosing a plumber in Ontario.
