Sioux Chief HYDRA-RESTER ASSE 1010 MIP Water Hammer Arrester

Sioux Chief HYDRA-RESTER ASSE 1010 MIP Water Hammer Arrester

The Sioux Chief HYDRA-RESTER is a MIP water hammer arrester built for rough-in supply lines behind the wall or under the fixture, available in 1/2" and 1" male iron pipe connections sized to ASSE 1010 fixture-unit demand across a branch line. It is engineered to absorb the shock wave created when fast-closing valves, solenoid-operated appliances, and single-lever faucets stop water flow abruptly, which is the mechanical cause of the banging and knocking commonly called water hammer. Each size threads directly onto a male iron pipe connection so a plumber can tie it into a threaded branch line during rough-in without reworking the rest of the supply run, and the line is ASSE 1010 rated so the correct size can be matched to the fixture units present on the branch.

Key Features

• Trade Size Range: Available in 1/2" and 1" MIP connections sized for standard branch supply lines feeding fixtures and appliances.
• MIP Connection: Male iron pipe threads allow the arrester to install directly into a threaded rough-in tee, stop, or riser without adapters.
• ASSE 1010 Rated: Sized to ASSE 1010 fixture-unit categories, the sizing method plumbers use to match an arrester to the number of fixture units on a branch line.
• HYDRA-RESTER Design: Sealed, air-chambered arrester body that cushions the pressure surge generated when a valve or solenoid closes quickly, rather than relying on an open air gap that can waterlog over time.
• Behind-the-Wall Installation: Installs on the supply line ahead of the fixture stop or appliance connection so the shock is absorbed close to its source, before it travels further through the branch piping.
• Compact Footprint: The MIP body fits inside standard wall and cabinet cavities alongside washing machine boxes, ice-maker outlets, and other rough-in supply fittings.

Why Sioux Chief?

Sioux Chief builds the HYDRA-RESTER line to the ASSE 1010 standard so plumbers and contractors can select the correct arrester size for the fixture units present on a given branch line, rather than guessing at capacity. Offering both 1/2" and 1" MIP connections makes the line a straightforward add to a threaded rough-in supply line during new construction or a remodel, and its sealed air-chamber design is intended to keep absorbing shock over repeated valve cycles instead of relying on an air gap that can fail. Sioux Chief manufactures the HYDRA-RESTER line in Canada, supporting consistent distributor stock for plumbing professionals sourcing rough-in supplies at volume.
