Frequently asked questions
Clear answers before you book
Does a backwater valve stop every kind of basement flooding?
No. It addresses reverse flow through the protected drainage path. Surface water, groundwater, foundation leakage and plumbing failures require separate controls.
Interior or exterior—which is better?
The correct location depends on the building drain, connected fixtures, property conditions, access, municipal requirements and the work needed to maintain the valve.
Does it need maintenance?
Yes. The valve should remain accessible and be inspected and cleaned according to the product instructions and site conditions.
Can Flood Ready help with rebate documents?
Yes. We can organize project records and explain the municipal submission process, but the municipality determines eligibility, approval and payment.
Why install a valve outside?
An exterior location can provide access to the building lateral without opening an interior floor, but suitability is property-specific.
Can two valves be installed?
Some properties have separate storm and sanitary laterals. Any dual-valve recommendation requires inspection and programme review.
Is exterior work eligible in Markham?
Markham currently lists eligible outdoor storm or sanitary backwater valves under its programme, subject to pre-approval and other requirements.
Is exterior work eligible in Halton?
Halton’s current application states that backwater valves must be installed inside the home to qualify for that subsidy.
How large is the opening?
The opening depends on the pipe depth, orientation, existing floor and selected valve. Flood Ready confirms the practical work area after assessment.
Will the floor be restored?
The installation scope should identify concrete restoration and any finished-floor work separately.
Can a valve be installed without a permit?
Permit requirements vary. Flood Ready confirms the applicable municipal path before work.
What should I receive after installation?
Project photos, equipment information, inspection records where applicable, invoice, maintenance guidance and rebate documentation relevant to the scope.
How often should a valve be checked?
Follow the manufacturer instructions and local risk. Annual review and checks after suspected activation are common planning points.
Can homeowners clean it themselves?
Only when they can do so safely and follow the product instructions. Professional help is appropriate when access, contamination or component condition is uncertain.
What if the valve is damaged?
Flood Ready can document the condition and discuss repair or replacement options.
Does maintenance guarantee no backup?
No system can be guaranteed against every event. Maintenance reduces avoidable failure risk within the valve’s intended function.
Do I need a new sump pit?
That depends on the existing foundation drainage, pit condition, pump arrangement and the work required by the local programme.
Where can the pump discharge?
The discharge point must follow municipal requirements and avoid recirculation, freezing, erosion and unsafe conditions.
