Region of Peel — Sanitary Backwater Valve Rebate

Peel pays 60% of your backwater valve — up to $1,500

A backwater valve is the one device that stops sewage from backing up into your basement during a storm — and the Region of Peel covers 60% of the invoice, tax included. Add the City's $1,500 storm-valve rebate and both pipes are protected for a fraction of the sticker price. Permit, inspection and paperwork: handled.

What this program does

The flood a sump pump can't stop

Sewer backup isn't rainwater — it's sewage, rising through your floor drain, basement toilet and laundry standpipe when the municipal sewer overloads. A backwater valve is the purpose-built fix.

How the install works:

1
Locate and camera-inspect the lateral
We confirm exactly where your sanitary line exits the house and that it’s a candidate for a valve.
2
Permit issued before any work
The Region requires the building permit up front — we apply, and work starts only once it’s granted.
3
Valve cut into the line
A small section of basement floor is opened near the foundation wall, the one-way valve is installed in the sanitary lateral, and the concrete is restored.
4
Municipal inspection passes
The inspector verifies the installation — required for the rebate, and your proof the job was done to code.
5
Peel reimburses 60%, up to $1,500
We file the rebate application with your paid invoice and permit records. The cheque comes directly to you.

Eligibility

The Region of Peel's rules, in plain English

✓Residential single, semi-detached or townhome in Mississauga, Brampton or Caledon.
✓Multi-unit dwellings or basement apartments sharing a sewer lateral are excluded.
✓Building permit issued before installation, with a passed inspection after.
✓No sanitary backwater valve rebate on the residence in the last 10 years.

The storm-side valve follows the City of Mississauga's Basement Flooding Prevention rules instead — including mandatory pre-approval before installation. When we bundle both valves, we sequence both sets of paperwork correctly from day one.

Terms & fine print

The rules that decide whether you get paid

Permit before install

The permit must be issued before the valve goes in. Install first and the rebate is gone — and the unpermitted work can resurface at sale time.

60% of the tax-in invoice

The rebate is calculated on your real invoice including HST, capped at $1,500. Labour, materials and restoration all count.

Once per 10 years

One rebate per residence per decade — the clock stays with the property, not the owner.

Sanitary vs. storm: two programs

Peel pays for the sanitary valve; the City of Mississauga pays up to $1,500 for the storm valve under its own program with its own pre-approval rules. Different pipes, different cheques — both claimable.

Reimbursement, not discount

You pay the invoice, then the Region pays you back. Your estimate shows gross price, rebate and net cost before you commit.

Region decides, not us

Approval belongs to the Region of Peel. We file applications that meet the published rules — paperwork done right is the whole service.

Why Proper Plumbing GTA

Permits, inspections and rebate filings — done for you

A backwater valve rebate lives or dies on sequence: permit first, inspection passed, paperwork matching the invoice. We run that sequence every week — it's the core of our business, not a favour we do on the side.

Rebate paperwork is our core service

The itemized quote, the contractor diagram, the permits, the pre-approval application, the final submission — prepared by the same team, every time. You sign online; we file everything.

Installed to the program spec

Every install is performed by a licensed master plumber, under municipal permits, exactly as the rebate programs require — because a rejected inspection is a rejected rebate.

Standardized, published pricing

Same price for the same work on every home. Your online estimate is the real number — itemized against each rebate so you see your net cost before anyone visits.

No approval, no install

Approval belongs to the City and Region — anyone who guarantees it is lying. If your pre-approval is declined, you don't proceed and you don't pay for installation.

The bigger opportunity

No sump pump yet? The City pays up to $7,500 — and the floor's already open

The expensive part of a valve install is opening the basement floor. A sump pump install opens it anyway — so doing both in one project shares that cost, needs one set of paperwork, and adds the City of Mississauga's flagship $7,500 Basement Flooding Prevention rebate on top of Peel's $1,500. It's our most common project for a reason.

FAQ

Backwater valve questions, answered straight

What does a backwater valve actually do?+

It’s a one-way gate installed in the sewer pipe where it leaves your home. Water flowing out pushes it open; sewage trying to flow back in — which happens when the municipal sewer overloads in a storm — pushes it shut. No electricity, nothing to operate. It just sits in the line and blocks the nastiest kind of basement flood.

Why are there two valves and two rebates?+

Most Mississauga homes have two separate sewer pipes: a sanitary lateral (sewage) and a storm lateral (rain/groundwater). Each can back up, each can get its own valve, and each valve has its own rebate from a different government — the Region of Peel pays 60% up to $1,500 on the sanitary valve, and the City of Mississauga pays up to $1,500 for the storm valve under its Basement Flooding Prevention program. Both can be claimed on the same home.

Do I need a permit?+

Yes — and it must be issued BEFORE installation, with a municipal inspection after. The Peel rebate requires it, and an unpermitted sewer alteration can also complicate a future home sale. We pull the permit as part of every valve job.

How fast does Peel pay?+

Peel is the fastest payer of the three programs: applications are typically processed in about 5 business days, and the cheque arrives in 4–6 weeks. Like the City's program, it's a reimbursement — you pay the invoice, then the Region pays you back 60% up to $1,500, tax included.

Can I claim it again if I move or upgrade?+

The rebate is one per residence every 10 years, so the valve should be installed correctly, to spec, the first time. If you buy a home whose previous owner claimed it recently, the clock came with the house.

Should I do this with or without a sump pump?+

If your home has no sump pump, do them together — the expensive part of a valve install is opening the basement floor, which a sump pump install already requires. One project shares that cost, needs one set of paperwork, and unlocks the City's $7,500 program alongside Peel's $1,500. If you already have a sump pump, the valve stands perfectly well on its own.
