Here is what to do:
1) Completely use any chemical that you have mixed in your tank. Do not leave any chemical inside the tank. If you have to, remove the pump and pour the chemical out onto ant mounds, or just pour it next the foundation of your home.
2) Use clean water and rinse the tank a couple of times and pour out the mix next to the foundation of you home.
3) Fill the tank with water, and insert the pump. Then pump it a few times and press the trigger and let water flow through the wand. Then release the pressure off of the tank and store it full of water. This keeps the tank, hoses and seals wet and hydrated.
Also next time you need to use it, it already has water in it, just add chemical.
This will prolong the life of any sprayer for years.
