How to Choose the Right Size Brass Stop Valve for Your Plumbing
2025-12-23
Choosing the correct Brass Stop Valve is crucial for a leak-free, efficient, and long-lasting plumbing system. An ill-fitting valve can lead to pressure drops, leaks, and costly repairs. As a trusted manufacturer with decades of expertise, Hongxiang understands that the right size is the foundation of reliable performance. This guide will help you navigate the key considerations to select the perfect valve for your project.
The selection process hinges on two primary dimensions: pipe size and valve connection type.
1. Identify Your Pipe Size (The Most Critical Step)
The valve size must match the outer diameter (OD) of your pipe. Common residential sizes include:
-
1/2" (15mm): Standard for most sink and toilet supply lines.
-
3/4" (20mm): Frequently used for main water lines and larger appliances.
-
1" (25mm): Common for main supply branches.
Pro Tip: Measure your pipe’s diameter with a caliper or wrap a string around it, measure the string length, and divide by π (3.14) to find the diameter.
2. Understand Connection Types
This defines how the valve connects to your piping.
| Connection Type | Description | Best For |
|---|---|---|
| Compression | Uses a ferrule and nut to create a seal. | DIY projects; no soldering needed. |
| Threaded (FIPT/MIPT) | Screws onto threaded pipe. | Easy installation and removal. |
| Soldered (Sweat) | Joined using a torch and solder. | Permanent, professional-grade connections. |
Brass Stop Valve FAQ
Q: Can I use a brass stop valve for both hot and cold water?
A: Absolutely. One of the key advantages of Hongxiang Brass Stop Valves is their excellent corrosion resistance and durability across a wide temperature range. They are perfectly suited for both hot and cold domestic water lines.
Q: How do I know if I need an angle valve or a straight valve?
A: This depends on your pipe layout. An angle valve (outlet is 90° to the inlet) is ideal for water lines coming out of a wall to connect to a fixture like a toilet or sink. A straight valve is used when the inlet and outlet are in-line, typically for straight pipe runs.
Q: What makes Hongxiang valves more reliable?
A: Hongxiang employs high-grade, lead-free brass alloys and precision CNC machining to ensure consistent wall thickness, smooth water flow, and superior sealing. Every valve undergoes rigorous pressure testing, guaranteeing it exceeds industry standards for durability and leak prevention.
Selecting the right Brass Stop Valve is an investment in your plumbing system's future.
