Protect Your Home From Basement Flooding 

Heavy rainfall and melting snow can overwhelm our sewer systems causing flooding in our community. To protect your property from damage, Markham's Private Plumbing Protection Rebate Program can offer you financial support for installing a flood protection device in your home, such as a backwater valve.
