1) this video depicts drainage system for the city of Regina. Other municipalities may not be constructed in the same manner. Consult with local experts.

2) Backflow valves only protect your home during backflow events.

3) (not included in this video) even during backflow events, it is possible for backflow valves to fail to function properly.
