How do you add pressure to the backpack sprayer?
Most sprayers have the pump on the lid.
Hand held sprayers have the pump on the lid that you hold. If you notice in the picture there is a rod that extends from the bottom of the pack. On backpack sprayers since you where it on your back, the rod extends out from your side and you pump the rod up and down to pressurize the tank.
