ABSTRACT:
In installing angle stop valves by a plumbing fixture such as below a sink, in a dwelling, where two capped stub-out pipes extend out from the wall and have respective hot and cold water under pressure, a new angle stop valve of this valve assembly is endwise directed over the sealing cap of the stub-out pipe, and also partially over the stub-out pipe, where it is then secured to the stub-out pipe. During and after this assembly its internal sealing gaskets bear against the stub-out pipe. When water is needed in an installed sink, the handle of this new angle stop valve is rotated causing its self-contained stainless steel pin to pierce the respective sealing end cap to create an orifice. Upon the withdrawal of this stainless steel pin, the water flows from the stub-out through the unsealed end cap, through this valve and on to the sink faucet. At all times during this installation the main water system of the dwelling remains turned on under pressure.
