You may especially want to check the siphon tube inside the tank that is responsible for the uptake of liquid inside the sprayer. You should also check the hose connection, and be sure the nozzle is not screwed in too tightly. When having a sprayer for a long time, you may also see the lining of the cylinder not lubricated enough, so you may want to apply a coat of Vaseline on the inside of the cylinder inside the tank to continue to hold the pressure inside.
