Abstract
A handheld fluid sprayer is configured to draw spray fluid from a reservoir mounted on the fluid sprayer and eject the spray fluid through a nozzle. The reservoir is removably mounted to the fluid sprayer. A filling apparatus can connect to the reservoir at the same interfaced that the reservoir connects to the fluid sprayer. The filling apparatus can be used to refill the reservoir. A priming pathway extends through the fluid sprayer and routes air out of the reservoir to prime the pump. The priming pathway extends from the reservoir and to a side of the pump opposite the reservoir. The nozzle includes a spray tip having a tip piece seated within a pre-orifice piece.
