SharkBite 3/4 Inch Crimp Ball Valve with Mounting Tabs and Drain
Best for mid-sized PEX runs where a mounting tab helps secure the valve to a surface. This lead-free DZR brass valve provides a drain or vent to remove water when servicing, and is compatible with PEX and PE-RT systems using copper crimps or stainless clamps. It’s selected for installers needing a sturdy, corrosion-resistant valve with a convenient drain feature.
- Drain/vent supports maintenance without fully disassembling lines
- Brass construction offers durability and long-term reliability
- Mounting tab aids stability during installation
Best for: Homeowners or pros wiring a compact branch with a drain-capable shutoff. Caution: Ensure proper crimp tool and ring compatibility for PEX connections.
SharkBite 3/4 Inch Crimp Ball Valve with Drain
Better for larger residential projects where a 3/4″ line needs a controlled shutoff and drainage. Features a drain/vent and compatibility with PEX and PE-RT through copper crimps or stainless clamps. The valve is built from lead-free brass for corrosion resistance and predictable operation over time.
- Drain/vent for line servicing
- Lead-free brass construction
- Good for 3/4″ feed lines
Best for: Situations requiring a robust 3/4″ valve in a residential loop. Limitation: Crimp tooling and fittings must match your PEX system type.
SharkBite 1/2 Inch Crimp Ball Valve with Mounting Tabs and Drain
Best for small-diameter lines where precise shutoff and drainage are needed. The 1/2″ size matches many branch lines in plumbing projects. Made from lead-free DZR brass, it resists corrosion and scale buildup. Mounting tab provides extra security when attaching to walls or cabinets.
- Drain/vent aids servicing without full line drain
- Sturdy mounting tab
- Corrosion-resistant brass
Best for: Tight spaces or feeds from a main line to fixtures. Caution: Verify the crimp or clamp method your system uses before purchasing.
SharkBite 1/2 Inch Crimp Ball Valve with Drain
Chosen for small PEX networks where a straightforward shutoff plus drainage is advantageous. This valve uses a 1/2″ size with crimp connections, suitable for connecting to PEX and PE-RT lines. The drain feature supports quick release of water from the line during servicing.
- Drain/vent ensures easy maintenance
- Lead-free brass construction
- Compatibile with standard PEX crimp rings
Best for: Serviceable lines in compact installations. Limitation: Data notes emphasize crimp rings or clamps; confirm tool compatibility before install.
1 Piece XFITTING 1/2″ Push Fit Ball Valve with Drain
Best for quick-fit installations where push-to-connect connections are preferred. The push-fit design supports copper, CPVC, or PEX piping with a single-step process. It includes a drain and is NSF/ANSI 61 certified, suitable for potable water systems. Note that it uses a different connection method than crimp or clamp systems.
- Push-fit connection for fast installs
- Drain feature for maintenance
- NSF/ANSI 61 certified

The valve is designed to work with crimp or clamp systems, depending on the installation. It’s designed for ANSI/NSF standards and general potable water use in many residential settings.
- Full-port design supports high flow
- Drain feature simplifies line servicing
- Broad PEX compatibility
Best for: Homes needing a robust 3/4″ valve with drain across longer runs. Limitation: Verify if your PEX system uses crimps or clamps to ensure you have the correct fittings.
Buying Guide: PEX Ball Valves With Drain
What should you consider when choosing a PEX ball valve with a drain?
- Size and flow: Match valve size to your pipe diameter (1/2″ vs 3/4″). Larger runs need bigger valves to avoid pressure drop.
- Connection method: Crimp, clamp, or push-fit connections affect tool requirements and reliability. Choose the method you already use in your system.
- Material quality: Lead-free brass (DZR) resists corrosion and scale, improving longevity in potable water applications.
- Drain feature: A built-in drain simplifies maintenance, especially for seasonal lines or zones that require occasional purging.
- Mounting options: Valves with mounting tabs offer added stability in tight spaces and along walls or cabinets.
- Certifications: Look for NSF/ANSI 61 or equivalent certifications for safe drinking water compatibility.
- Maintenance and replacement: Consider availability of spare parts (crimp rings, clamps) for the chosen system.
What makes a drain-capable valve preferable?
- Facilitates routine draining without fully disassembling the line.
- Helps relieve pressure during service and reduces risk of air lock.
How to install safely?
- Turn off the water supply and drain the system before installation.
- Use the appropriate tool for your connection method (crimp, clamp, or push-fit).
- Follow manufacturer guidance for securing mounting tabs and ensuring leak-free joints.
FAQ
- What is a PEX ball valve with drain used for?
It allows isolation of a water line and draining of water when servicing or replacing sections of PEX piping. - Are these valves compatible with all PEX brands?
Most are designed to work with common PEX/PE-RT systems, but compatibility depends on the connection method (crimp, clamp, push-fit). - Is lead-free brass important for plumbing valves?
Yes. Lead-free brass (DZR) reduces lead exposure and improves durability in potable water systems. - Does a mounting tab improve valve installation?
Yes. A mounting tab helps stabilize the valve on walls or cabinets, reducing movement after installation. - Which size should I choose?
Pick 1/2″ for smaller lines and 3/4″ for medium to larger branches. Match to your pipe diameter for best flow and leak-free connections. - Do I need additional parts?
Depending on the system, you may need copper crimps, stainless clamps, or PEX adaptors that fit your pipe and valve.
