N O T E
Use only water to pressure test hose assembly
Inspect hose assembly covers (1) for cuts, abrasion, burns, rodent damage and mildew or chemical
Inspect couplings for corrosion, damage or frozen swivels, overall condition of metal and condition of
Damaged hose must be removed from test area and, repaired before being pressure tested.
Select a test area that will allow connection of hydrostatic test equipment to an adequate water source.
Surface of test area should be level, smooth and free of any materials that can damage hose by cutting
C A U T I ON
At no time shall the total layout exceed 500 feet (150 m).
Hose must be tested one length at a time.
Make sure hoselines are layed out straight and without kinks or twists.
Connect one end of hoseline (1) to discharge valve (2) on pump (3). (Reference 2-7b)
C A U T I ON
A hose test valve should be used to prevent an excessive pressure surge to the
equipment should a hose burst during test.
Connect hoseline (1) at hose test valve at approximately 10 inches (154.0 mm) to 15 inches (381.0 mm)
