Water Flow Test Report

The most common test involves measuring the flow of water flowing out of a municipal fire hydrant while recording how much the water pressure has dropped.

Water flow test report. An alternative approach is to ask your county health department. 4 2 a typical town main can be tested at a single hydrant using a suitable flow and pressure test instrument. The design flow is the total flow from the test and the design head is equal to the residual pressure at hydrant 1. A water flow test also known as a hydrant flow test is a way to measure the water supply available at a building site usually for the purposes of installing a water based fire protection system.

The shutoff head is equal to the static pressure head at hydrant 1. 4 3 larger mains of higher capacity will require the simultaneous testing of several hydrants. You will receive a report that includes the static and residual pressure of the main and the flow rate at each hydrant. Click here for a sample fire hydrant flow test report.

4 1 the flow test procedure is carried out by measuring the flow of water available from the distribution system at the rating pressure. A home inspector will sometimes run the water flow test while performing the home inspection. When the results are collected carefully formulas can be applied to figure the varying pressure that will be available when different amounts of w. In order to use the flow test results in a water model you must create a 3 point pump curve.

The shutoff flow will always be 0 gpm. The report will be emailed or faxed to the attention of the person on the request letter.
