Buying Guide: Key Purchase Considerations And Comparisons
- Connection type and size: Most residential units use 3/8″ compression or 3/4″ fittings. Match the arrestor to your dishwasher supply line or appliance inlet to minimize compatibility issues.
- Material and durability: Stainless steel bodies and brass components offer corrosion resistance and longer life in moist environments. For higher-stress installations (e.g., washing machines), prioritize sturdy construction.
- Pressure and temperature ratings: Choose models rated up to at least 250 PSI and 180°F to handle common household water conditions and hot water supply scenarios.
- Install orientation: Some arrestors are rated for vertical or horizontal installation. Verify your plumbing layout and select a model with flexible mounting options if space is constrained.
- Certifications and safety: Look for UPC, NSF, or cUPC certifications and lead-free materials to ensure compliance with drinking water standards.
- Noise reduction performance: The primary purpose is dampening water hammer. Consider models with proven noise reduction and a design that minimizes pipe movement near sensitive fixtures like dishwashers and toilets.
- Number of units: For laundry or multi-fixture setups, packs (e.g., 2-pack) can provide easier distribution and maintenance across multiple connections.
- Ease of installation: Devices that require minimal disassembly and straightforward compression fittings save time and reduce the chance of leaks during setup.
- Warranty and support: Favor brands that offer warranties or clear support channels in case of installation questions or part replacements.
