Three Way Angle Stops
Designed to allow the shutoff of multiple fixtures, three way valves are commonly used in the residential kitchen to allow isolation of a faucet and a dishwasher or a faucet and a filter, in the case of repair or replacement. Three way valves with one handle turn off the water at the point of entry, helping to prevent water damage.

Frequently Asked Questions
Q. "What does compression style and 1/4 turn style (angle stop or straight stop) mean?"
A. The compression style in this case is referring to the way the water is shut off when the valve is closed. Please do not confuse this with the inlet or outlet size which can also be referred to as "compression". The handle is attached to a stem with a rubber washer on the other end. As the handle is turned to close the valve (clockwise), the rubber washer is forced (compressed) against the "seat" which is the metal opening of the waterway. 1/4 turn style valves have inside the stem a port that when the handle is turned one quarter of a turn counterclockwise, the valve is open fully and the same quarter turn in the opposite direction closes the valve completely.
Q. "How do I know if I need 1/2" Fip inlet or 5/8" o.d. inlet angle stops?"
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.
Q. "What is the difference between 'nominal' dimensions and 'outside diameter (OD)' dimensions?"
A. Nominal is the term used to describe most pipe and fitting measurements in the plumbing industry. Nominal refers to the inside diameter measurement of the pipe. The actual inside pipe measurements will vary slightly due to the wall thickness of the pipe, so it is referred to as "nominal" meaning a small variance of size. The outside diameter (OD) dimensions refer to the actual outside diameter of the pipe. The outside diameter dimensions of pipe are a constant size which allow pipe fittings to be used with the same type of piping with multiple grades of wall thickness.
Q. "Some of the outlet sizes are shown as 3/8" OD or 5/8" OD compression nut w/sleeve. Is this measurement referring to the outside diameter of the compression nut?"
A. No, it is not. Copper compression fitting sizes are measured and sized according to the outside diameter (OD) of the copper tubing or copper pipe for which they will be used.
Q. "How are lead levels in drinking water currently regulated?"
A. The United States Environmental Protection Agency (EPA) regulates the amount of lead and other contaminants in drinking water under guidelines established in the 2014 Federal Safe Drinking Water Act.
Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be "essentially lead free" (less than 0.25% weighted average). For further information about how the law determines what is "lead free", rules regarding which plumbing products must be "lead free", and who these laws will affect, please view our page.
