Overflow and Flood Protection for Break Tanks in Commercial Buildings

Oct 25, 2018 10:06:00 AM / by Tim Zacharias posted in Level, Flood Protection

Many commercial buildings in Houston have large water storage tanks to meet city plumbing code requirements. These break tanks provide water for fire protection pumps and domestic (potable) water pumps to supply the building. A major concern with break tanks in the building is the potential for flooding due to tank overflow. This is especially critical when the tanks are in a basement level.

Why is a Break Tank Required in Houston for Pumping Applications?

The Houston Amendments to the Uniform Plumbing Code states that upstream from a pump system, an atmospheric storage tank with an air gap between the tank and city water supply must be used. This applies any time the city water pressure is insufficient to supply a building for both Domestic (potable) and Fire Water applications and the addition of pumps is required.
