How does an angle stop water supply valve work?

A. Angle or straight stops have an inlet that is either 1/2″ fip (female iron pipe) or 5/8″ o.d. copper compression. The 1/2″ fip stops are for attaching to threaded pipe nipples. The copper compression fittings are designed to attach to the smooth outside surface of copper pipe. 5/8″ o.d. compression would fit a 1/2″ nominal piece of copper.

How does a compression stop valve work on a copper pipe?

Compression stop valves are most commonly used to install a shutoff valve on a rigid copper pipe. This type of valve has a brass ring, called a ferrule, and a compression nut that squeezes the ferrule into the pipe connection to make a watertight seal. Compression valves are easy to install with just a pair of pliers or wrenches.

Can a sweat valve be removed from a copper pipe?

A copper sweat valve is designed to be sweated, or soldered, to a rigid copper pipe. This requires soldering tools, such as a torch, flux, emery cloth, and solder. Sweat valves are not easily removed once they are installed because they have to be heated to melt the solder so you can pull the valve off of the pipe.

What kind of shutoff valve do I need for a galvanized pipe?

This type of valve is commonly found on galvanized or brass-threaded pipes, but it can be adapted to other types of pipes by using a male iron pipe adapter that connects to the pipe and then screws into the shutoff valve. Iron pipe valves simply screw and unscrew from the end of the pipe.

How do you install a compression valve at Home Depot?
