2. Preventing Sewer Flooding In Homes and Businesses
So, what causes the flooding problems?
Solid materials flowing down sewer lines cause blockages – especially when getting stuck in root balls
Hot fats and oils dumped in sewer lines, solidify and combine with other solid materials in the sewer water to form balls and this creates blockages
Damage to downstream pipelines – for instance pipe damaged by construction equipment blocks pipe flow
Debris swept along with storm water causes blockages in storm water pipelines

Residential Example
Obstructions in main sewer line causing sewer water to back up into homes of higher elevation

5. How the Blokker Valve Came To Exist
SecureLeak Inc. developed, designed, patented, certified and manufacture the Alarmed Blokker Backwater Valve on
request of INTAC (previously ING) Insurance Company:
Existing backwater valves were/are not reliable
Leaking under pressure only keeping back solids
Regular Service requirement by Licensed Plumber
No pressure wave protection to prevent valve failure and flooding
Do not comply with Canada Plumbing Codes regarding sewer line venting
Residential sewer flooding causes Billions of Dollars in damage
INTAC required reliable protection and early warning for the home owner
INTAC required a valve with no regular service requirements
INTAC required a product that would minimize their financial liability
Blokker Backwater Valve Information Slide 5

6. How the Blokker Valve Came To Exist
The Blokker Backwater Valve design parameters were as follows:
Venting of downstream pipelines
Providing sewer line venting as per Canada Plumbing Code requirements
Releasing of pressure waves / surges through vent
Easy installation, straight retrofit, inside or outside building
Alarm warning/monitoring with high sewer line water level
Second alarm warning/monitoring when Blokker Valve closes
No regular inspection / service requirements between backups
Special embedded seal to eliminate leaking at all pressures
No obstructions / transitions in flow path through Blokker Valve
Alarm warning for clogged mechanisms after backup situation

7. How the Blokker Valve Came To Exist
The result after many hours of hard work and many Dollars:
The Blokker Back Water Valve!
CSA Certified, Patents Pending Canada & USA
