Inspect all components for cracks, wear and other visible damage.
Inspect all hose sections (2) thoroughly. Look for cracks, squashed sections, broken fittings, missing
or damaged gaskets, missing hose clamps, hose damage near fitting, etc. Make sure no gravel or
debris are inside hose sections.
Inspect check valve (11) to make sure it is oriented correctly with the bolt in the vertical position.
Also insure that the wings of the valve move freely and that the rubber sealing portions are not
damaged.
Inspect the guard (2 1). If damaged, replace.
Inspect the screen (22) for imbedded sand particles. Use a wire brush to remove any sand.
Inspect the wellpoint tip (24) to make sure the rubber coated ball is in place. Make sure that the ball
can seat freely and no debris is present. Make sure that the rubber coating on the ball is not damaged.
If ball is damaged, replace wellpoint tip (24).
Inspect the gate valve (4) to make sure it turns freely from the fully open position to the closed
position. Make sure the packing nut is tight.
NOTE
If hose is damaged within four foot of the end, the hose should be shortened, instead of
repaired with a coupling.
If repairing the end of a hose, remove the hose clamps (26) from the end being repaired. Remove the
fitting (27) from the hose (28) end (it may be necessary to slit the hose with a knife or hacksaw to
remove the fitting).
For all damaged hose, cut the damaged hose area off squarely. If making a repair other than at the end
(a splice) cut enough hose away to ensure all damaged areas are removed.
Slide hose clamps up onto the hose near the repair.
Lubricate the outside of the coupling or end fitting (whichever is applicable) with silicone adhesive.
Push coupling (29)or end fitting (27) into the hose (28). Two people might be necessary.
Tighten hose clamps (26).
