Angle Valve FAQ
1. What is the primary advantage of using an angle valve?
Angle valves provide a space-saving solution in plumbing systems by redirecting water flow at a 90-degree angle, making them ideal for tight spaces behind toilets, under sinks, or in cabinet installations. Their compact design allows for easier access in confined areas compared to straight valves while maintaining full water flow capacity.
2. How often should angle valves be replaced?
High-quality angle valves typically last 8-10 years with normal use. However, we recommend inspecting them annually for signs of leakage, corrosion, or difficulty in operation. In areas with hard water, mineral buildup may require more frequent maintenance or earlier replacement. Proactive replacement during major plumbing renovations can prevent future leaks.
3. Can angle valves be used for both hot and cold water?
Yes, most modern angle valves are designed for both hot and cold water applications, with temperature ratings typically up to 120°C. However, verify the manufacturer's specifications as some specialized valves may have different temperature limits. The materials used (brass body, EPDM seals) ensure durability across typical residential and commercial water temperature ranges.
Installation Guidelines
Proper installation ensures optimal performance of angle valves:
- Shut off main water supply before installation
- Clean pipe threads thoroughly
- Apply thread sealant or Teflon tape
- Hand-tighten first, then use wrenches for final tightening
- Avoid overtightening to prevent thread damage
- Test for leaks before finalizing installation
Maintenance Tips
- Exercise valves periodically to prevent seizing
- Check for drips or moisture around valve connections
- Clean mineral deposits from aerators and screens
- Replace washers if weep leaks develop
- Keep valves accessible for emergency shut-off

| Industrial Use | Heavy-Duty Angle Valve | Reinforced construction, high-pressure rating |
Additional Angle Valve FAQ
4. What's the difference between angle valves and straight valves?
Angle valves change the water flow direction by 90 degrees, making them perfect for corner installations, while straight valves maintain water flow in the same orientation. Angle valves typically require less space behind fixtures and allow for easier shut-off access in cramped areas. Straight valves offer slightly better flow characteristics in straight pipe runs.
5. Are all angle valves the same size?
No, angle valves come in various sizes from 1/4" to 2" to accommodate different pipe diameters. The most common residential sizes are 1/2" and 3/8", while commercial applications often use 3/4" valves. Always match the valve size to your existing plumbing and verify thread type (BSP, NPT) for proper compatibility.
6. Can I install an angle valve myself?
While DIY installation is possible for experienced homeowners, we recommend professional installation for best results, especially in locations without easy access to main shut-off valves. Proper installation requires pipe preparation, correct sealing techniques, and leak testing. Improper installation can lead to water damage, so assess your skills carefully before attempting.
