Water hammer is one of those problems that rarely announces itself during design reviews. On drawings, tall fire risers look orderly and predictable—vertical pipe runs, zone valves at clean intervals, pumps sized with comfortable margins. Everything appears controlled.
Then the system is tested.
Or worse,...
Fire protection piping systems in high-rise buildings are often designed under intense time pressure. Pipe sizes are calculated, valves are specified, layouts are coordinated, and drawings move quickly toward approval. On paper, everything looks controlled. Yet many systems that pass inspection without...
Fire protection piping systems often get treated like background work. Draw the lines, size the pipe, call out the valves, and move on. On a schedule-driven job, that’s a tempting way to think.
But the systems that behave well for twenty years usually weren’t “finished” when the drawings were stamped....
In high-rise fire protection projects located in hot and desert environments, check valve selection rarely feels like a critical decision at first. Valves are sized, pressure ratings are confirmed, and drawings move forward. On paper, most options appear compliant. In reality, check valves in these regions...
