Buying Guide: Key Purchase Considerations
Selecting the right commercial water hammer arrestor involves evaluating system needs, installation constraints, and maintenance expectations. Consider the following factors:
- Connection type and size: Match MIP, FIP, or push-to-connect options to your piping. Note thread sizes (1/2″, 3/4″, etc.) and whether sweat, press, or crimp fittings are supported.
- Material construction: Copper, stainless steel, and brass options offer different corrosion resistance and durability. Stainless steel is often preferred in wet or harsh environments, while copper works well in standard domestic/commercial lines.
- Orientation and mounting: Some units are designed for horizontal or vertical installation; others fit within tight wall cavities. Ensure compatibility with your space constraints.
- Pressure and temperature ratings: Verify working pressure (PSI) and temperature range align with your system’s operating conditions and the water supply characteristics.
- Shock and cycle expectations: High-cycle units can handle repeated starts and stops without performance loss, which is critical in commercial applications with frequent usage.
- Maintenance and accessibility: Some models are certified to require minimal maintenance, while others may necessitate periodic checks or panel access.
- Cost of installation and retrofit: Consider labor time, ease of retrofitting into existing lines, and compatibility with common fitting systems (Viega, push-fit, etc.).
- Warranty and testing: Look for products with laboratory testing, extended lifecycles, and recognized certifications to ensure reliability over time.
