Water Flow Test Report

A home inspector will sometimes run the water flow test while performing the home inspection.

Water flow test report. You will receive a report that includes the static and residual pressure of the main and the flow rate at each hydrant. The shutoff flow will always be 0 gpm. In order to use the flow test results in a water model you must create a 3 point pump curve. During the course of the test the water flow should be monitored and re measured every 15 minutes to make sure that a constant flow rate is maintained.

An alternative approach is to ask your county health department. One way to understand your results is to ask the lab that did the testing. 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 design flow is the total flow from the test and the design head is equal to the residual pressure at hydrant 1.

The report will be emailed or faxed to the attention of the person on the request letter. 4 1 the flow test procedure is carried out by measuring the flow of water available from the distribution system at the rating pressure. 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. Interpret your water test results many well owners need help understanding water test results.

The shutoff head is equal to the static pressure head at hydrant 1. When the results are collected carefully formulas can be applied to figure the varying pressure that will be available when different amounts of w.
