Submersible Well Pumps in Orillia & North Bay — Installed Right, Sized Right, Built to Last

If your well pump fails, everything stops — no showers, no laundry, no drinking water.

At Poly-B Plumbing, we install and replace submersible well pumps for homes, cottages, and rural properties across Ontario. With 40+ years of experience in well systems, we don’t guess. We size, install, and test every pump to match your well depth, draw rate, and pressure needs — all done to code, with proper protection.

What Is a Submersible Well Pump?

A submersible pump sits inside your well, pushing water up to your pressure tank. It’s fully sealed and wired — and it needs to be sized correctly based on:

Well depth

Static water level

Household demand

Distance to tank

Pressure tank specs

GPM and Regeneration of well

If your pump is too small, it won’t meet demand. If it’s too big, you’ll cycle the tank too often — shortening its life.

We handle both new installs and replacements, and we’ll walk you through the options.

Our Pump Replacement Process

Step 1

Diagnose the Issue

We check wiring, switches, pump control boxes, and draw levels before removing anything.
Step 2

Pull the Old Pump

We extract the existing pump, inspect the well casing, and check static water level.
Step 3

Select & Size New Pump

We calculate GPM, depth, pressure needs, and tank specs. Then we recommend the correct horsepower and model.
Step 4

Install with Proper Electrical & Plumbing

New pump, electrical connection, check valve, torque arrestor, and secure plumbing — all sealed and tested to code.
Step 5

Test Flow, Pressure, and Recovery

We test everything before we leave — from pump response to pressure switch function to flow at your furthest tap.

When to Replace Your Well Pump

Intermittent or no water pressure

Air sputtering from taps

Breaker tripping when pump starts

Rapid on/off cycling

System more than 10–15 years old

Visible corrosion or frayed wiring

Low flow at fixtures despite working tank

We'll confirm if it's the pump, the pressure tank, or another part of the system before quoting any replacement.

Frequently Asked Questions

How long should a well pump last?
