(Pack of 2) EFIELD S-241 Water Hammer Arrestors
EFIELD’s S-241 model provides two stainless steel arrestors designed for washing machine supply lines. The units feature a 3/4 inch female swivel hose thread (FHT) to 3/4 inch male hose thread (MHT), enabling flexible routing. With a maximum working pressure of 250 PSI, these arrestors are suitable for typical residential water systems. They can be installed horizontally or vertically, offering installation versatility in tight laundry spaces or utility rooms. The stainless steel construction emphasizes durability and long service life in damp environments.
Sioux Chief 660-HB Water Hammer Hose Arrestor
Sioux Chief’s 660-HB is a straight compressor-style arrestor designed for easy retrofits on 3/4 inch lines. It supports straight 1/2 inch copper legs and is compatible with various fittings, including press-fitting systems and push-fit configurations. This model is favored for renovations where space allows a longer, linear path for the arrestor to absorb shock. It’s built to resist corrosion and delivers reliable protection against water hammer in standard home plumbing runs.
(Pack of 2) EFIELD MH-S-241 Angle Stainless Steel Arrestors
These angle-configured arrestors from EFIELD extend the S-241 design into tight spaces, offering two stainless steel units with 3/4 inch FHT x 3/4 inch MHT connections. The 250 PSI maximum working pressure aligns with standard household systems, and installation can be horizontal or vertical. The angled form helps route lines around appliances or ventilation to minimize water hammer near compact laundry setups or under sinks, while stainless steel ensures robust corrosion resistance over time.
Sioux Chief 653-B Hydra Ester Water Hammer Arrester
The Hydra Ester line from Sioux Chief is designed for higher resilience in piping systems. Factory and laboratory testing support extensive shock cycles, with compatibility for both sweat fittings and press-fitting systems. This model is well-suited for installations within standard wall cavities, such as behind clothes washers or in utility rooms. It is specifically engineered to handle long-term cycling without failure, offering durable support in homes with frequent valve shutoffs.
SECKWHALE Stainless Steel Water Hammer Arrestor for Washing Machine
SECKWHALE offers a straight water hammer arrestor designed for 3/4″ GHT connections, with a maximum operating range up to 250 PSI and 180°F. The units are brass-bodied, providing corrosion resistance and durability for residential environments. Noise reduction is a key feature, helping to dampen pipe banging when washing machines and other appliances shut off. The 2-pack configuration supports multiple connections along a cold or hot water line, improving overall system quietness and stability.
Orianse 2 Pack Washing Machine Water Hammer Arrestor
The Orianse 2-pack provides 3/4 inch MHT to 3/4 inch swivel hose FHT connections in a stainless steel straight format. Lead-free brass construction delivers corrosion resistance, and the arrestors are ASSE1010, NSF/ANSI 61, and cUPC certified, ensuring compliance with common plumbing standards. The units are designed to absorb kinetic energy from valve closures, with installation recommended on both hot and cold washer inlets for maximum effectiveness. A robust choice for durable, long-term service in busy laundry areas.
Buying Guide: Key Purchase Considerations
- Connection type: Ensure the arrestor’s thread sizes match your supply lines (for example, 3/4″ FHT/MHT or 3/8″ compression), so installation is straightforward without adapters.
- Material and durability: Stainless steel and brass bodies excel in corrosion resistance and longevity, especially in damp laundry rooms or basements.
- Pressure and temperature ratings: Look for models rated up to at least 250 PSI and 180°F to handle typical home cold/hot water lines and occasional high-temp usage.
- Configuration: Straight versus angle designs offer installation flexibility in tight spaces or behind appliances. Consider whether you need two units or a single inline device.
- Certification and testing: Models labeled with ASSE/ANSI certifications or extensive cycle testing indicate adherence to industry standards and reliability over time.
- Installation location: Place arrestors on hot and cold lines near washing machines or dishwashers to dissipate closing energy where it is generated.
- Maintenance and life cycle: Some units are designed for high-cycle testing (e.g., hundreds of thousands of cycles). This matters in households with frequent valve usage or older plumbing.
- Warranty and brand support: Reputable brands with clear warranty terms help with future service needs and replacements.
In selecting the best water hammer arrestor for a home system, weigh space constraints, preferred installation orientation, and whether you want a single unit or a two-pack to cover multiple lines. Stainless steel and brass models typically offer superior durability, while compression and sweat-fit options provide compatibility with popular plumbing methods.
