Is your sprinkler system capable of protecting your building? We hydraulically calculate your sprinkler system and provide an engineer's signed report. You can send it to the fire department and your insurance company to show that your building is fully compliant with current requirements. If upgrades are needed - we will tell you what has to be done to minimize expenses.

The sign of fire sprinkler systems is usually done using the Hazen Williams formula. Most piping systems in fire protection systems can be classified into three types.


1) TREE

This structure uses a main pipe that branches to progressively smaller pipes. A tree trunk from which branches come out is similar to this layout.

2) LOOP

There is a main pipe from which other pipes branch out but the main pipe returns to its starting point creating a loop.

3) GRID

There are two main pipes running parallel to each other. Piping runs are connected to both main pipes. There is more than one way for water to each a given point in the system, so fiction is reduced.
