This product has many features, but keep in mind: Before setting up the valve at the pipeline, open it completely. Inspect inside the body and the threaded components to be dean, and possible contaminants have to be taken out so as to guarantee proper functioning. If compressed air is at your disposal, utilized it for a finer cleaning. Screw the valve at the threaded pipe through an appropriate wrench. To get a correct sealing on threading, it is beneficial to make use of PTFE, hempen tape or other suitable product.
