ABSTRACT:
A waterline injection nozzle for introducing water treatment chemicals within a high pressure waterline. The apparatus has a quick disconnect fitting attached to a non-corrosive stainless nozzle assembly. Within the nozzle assembly is an integral ball valve. The apparatus can be disconnected from the waterline with both the flow of chemical solution and the water from the waterline prevented from spraying or leaking. The integral ball valve in the nozzle assembly serves to depressurize the quick release fitting, so that it can be easily and quickly reconnected. A one-way flapper valve that prevents water flowing from the waterline to the chemical reservoir is also provided.
