Frequently asked questions
What is a backwater valve?
A backwater valve is a check-valve style device that allows flow out of the home under normal conditions and helps prevent sewage or stormwater from flowing back into the home during surcharge or backup conditions.
Should the valve be indoor or outdoor?
It depends on pipe layout, access, municipality, lateral type, property condition, and rebate or permit requirements.
Do you install on sanitary and storm laterals?
The site is built around both sanitary and storm lateral backwater valve pathways where appropriate.
Do you guarantee rebates?
No. We support private work and documentation. Toronto or Markham determines approval and payment.
Can you help with insurance documents?
Yes. We can help organize project records, invoice details, photos, and installation information for homeowner insurance conversations.
