Sprinkler Hydraulic Calculations
Hydraulic calculations and water supply analysis for a sprinkler layout, sealed for the permit.
Hydraulic calculations prove that a sprinkler system will deliver the required density over the design area with the water supply available at the site. Plan examiners ask for them with the sprinkler permit and in response to comments. We prepare and seal the calculations from your layout and flow test in five to ten business days.

Frequently asked questions
Can you calculate a contractor's layout?
Yes. We calculate the system as drawn, report whether the water supply is adequate, and recommend changes where it is not.
Do you need a current flow test?
Yes. Most authorities require a flow test less than a year old. We can request one from the water purveyor if you do not have it.
Have a project in design or permitting?
Send us the drawings you have, even if they are early. We reply within one business day with scope, fee and schedule.
