Loose hose. One of the common causes is not having the hose installed properly. Remove the hose from the tank. Most sprayers have a hose barb (2 plastic, white tabs) located at the end of the hose under the hose nut. Reinsert the dip tube into the tank making sure to align the hose barb with the cut outs (see picture below). Push the tabs down into the notches until they cannot go any further. Then hand tighten the hose nut onto the tank – being careful not to cross thread or overtighten. If your sprayer does not have a hose barb, you can just reinsert the dip tube into the tank and hand tighten the hose nut as described previously.
Cracked, swollen or faulty hose. If the hose becomes cracked or swollen, it will need to be replaced by ordering a shut-off assembly.* Note: The hose cannot be removed from the shut-off.
