Removing the hose kinks
By Mark van der Feyst
In large-diameter supply hose, we invariably create a few kinks when deploying the line from a hydrant connection to the apparatus intake. This can be caused by too short of a distance from the hydrant to the pump intake, a sharp bend in the hose when coming off the hydrant, or improperly flaking out the hose.
Regardless of the reason, one kink in the hose line will reduce the water supply in both pressure and amount. One way to alleviate kinks, as shown in the photo, is to make a big “O” with the supply line between the hydrant and the pump intake.
When the hydrant is fully opened, the pressure from the hydrant will cause the hose to be pushed out uniformly making a smooth circle with no kinks. This pattern can also reduce the distance the hose has to be flaked out when space is restricted. This can be done easily before the hose is charged and will not delay the securing of the water supply.
