Why Is My Mist Sprayer Not Working?
what could be your bottle’s problem-
The nozzle of the bottle could be blocked- If your spray bottle contains oil or anything else that can harden, such as hairspray, you should periodically clear the nozzle. How? Unscrew and remove the cap and hold it under hot, running water or immerse it in vinegar, then use a pin to poke a hole in any blockage in the nozzle itself. If your bottle contains hairspray, soak the nozzle in alcohol. If the blockage is unusual, unscrew the entire sprayer from the bottle and soak it in vinegar.
The spring might be broken- When you pump the piston and it doesn’t retract, the reason might be a broken or missing spring, but sometimes the spring just pops out of position. If you could access the spring, then you can get a replacement in any hardware store. If the spring isn’t accessible or the piston seals fail, you need to replace the sprayer.
Everything seems to be fine but very little liquid is being dispensed- When the seals fail and the trigger works, but the sprayer delivers very little fluid, you may be able to improve the sprayer performance by spraying vegetable oil through it.
Maybe the inner tube isn’t immersed in fluid- The plastic tube connected to the sprayer is designed to reach the bottom of the bottle, but it often curls up, and the end protrudes from the liquid in the bottle when the level is low. You can prevent the curling up of the tube by with a one-foot length of 1/8-inch plastic tubing from a hardware store. Cut the existing tube so that only an inch remains attached to the sprayer, then push the 1/8-inch tubing over it and attach 1/8-inch metal nuts to the other end. The weights keep the tube immersed even when you tip the bottle on its side or turn it over.
But, if it seems impossible to figure out what is wrong with the sprayer, it is best to dispatch the sprayer and all other components and re-fixing all the parts again to make it work.
