  1. Dive Into Suction Tank Issues and Inspections

    Leave a Comment

    Privately-owned water tanks supplying fire protection systems have a long history. The NFPA published the Standard on Gravity Tanks in 1909. It is one of the oldest NFPA codes, predating even the Life Safety Code’s precursor, the Building Exits Code, first published in 1927. The Standard on Gravity Tanks evolved over the years to become NFPA 22, Standard for Water Tanks for Private Fire Protection. The inspection, testing, and maintenance requirements for all types of private fire water storage tanks are laid out in NFPA 25, Chapter 9 – Water Storage Tanks. While there are about eight different types of fire water tanks, I’d assert that the most common type today is the steel suction tank. (more…)

  2. A Primer On The Elements Of Fire Protection Water Supplies

    Get primed!

    Fire protection water supplies can be made up of one or more common elements, including tanks, pumps, water sources and water systems. Sometimes elements are used together to develop an adequate supply for fire protection.

    An adequate water supply for a fire protection system will meet the needs of the fire protection system (plus safety factor) in three terms: (more…)

  3. Fire Pumps are Cool 😎; Lets Keep Them That Way

    In my last blog, we discussed the small PRVs that go on wet sprinkler systems to limit their pressure below 175 psi. That brought to mind a small PRV in another application that is used to keep something different cool: an electric motor-driven centrifugal fire pump. I can’t talk about electric fire pumps without also talking about diesel fire pumps, so let’s dive in and take a look at both! (more…)

  4. Wet System Pressure Release Valves

    Ah, summertime. Summer’s heat brings some good things: opportunities for outdoor swimming and seasonal produce: blueberries, and peaches, and watermelon…

    Summer’s heat doesn’t bring all good things. It can even trigger issues with fire sprinkler systems. Let’s zoom in on a small component on a wet fire sprinkler system that’s there in part because of summer heating: a pressure relief valve.

    A pressure relief valve (or an auxiliary air reservoir) is required on wet sprinkler systems; one reason is to (more…)
