Sump Pumps & Backwater Valves
A working sump pump and backwater valve are the difference between a dry basement and a flooded one. We install, test, and maintain both.
Does This Sound Familiar?
- Your basement has flooded or feels damp
- The sump pump runs constantly or not at all
- Strange noises from the pump pit
- You don't have a backwater valve and the street has flooded before
- The pump is over 7–10 years old
- Water is backing up toward your floor drain during storms

What's included
- 1
Inspect the pit and pump
We check the pump, float, check valve, discharge line, and pit condition — and test it under load.
- 2
Assess backwater protection
We look at whether a backwater valve is present and functional to stop sewer backup during storms.
- 3
Install or upgrade
We size the right pump, install a battery backup if you want one, and fit or service the backwater valve.
- 4
Test and maintain
We test the full system, show you how to check it yourself, and set you up on a service schedule if you want.
Upfront, Flat-Rate, No Surprises
Flat-rate installation — pump, labour, and materials in one number.
Battery backup and high-end pumps are quoted as clear options, not surprises.
Backwater valve installation is a separate transparent quote.
Repair vs. Replace
The factors that push a job one way or the other — straight, no pressure.
- A failed switch or float on a newer pump is a repair.
- A pump over 7–10 years, or repeatedly failing, is a replacement.
- No pump at all in a wet basement is an install — don't wait for the flood.
Why Choose Dea Mechanical for Sump Pumps & Backwater Valves
We size the pump to your pit and water volume, not a one-size guess.
Battery backup options so your pump works when the power doesn't.
We test under load — a pump that runs isn't always one that pumps.
