Sioux Chief 656-E Hydra-Rester Water Hammer Arrester, 1", ASSE 1010

The Sioux Chief 656-E Hydra-Rester is a 1" water hammer arrester engineered to absorb the pressure shock that occurs when fast-acting valves and appliances slam shut on a supply line. Certified by ASSE to the ANSI/ASSE 1010 standard, this arrester is available in either a 1" MIP threaded connection or a 1" MSWT sweat connection, letting plumbers choose the connection style that matches the rough-in method used on the job — threaded iron pipe or copper solder joints. Across both connection options, the shared 1" trade size, ASSE 1010 certification, and 10,000-cycle rating stay constant, so the only variable is how the arrester attaches to the supply line. Regardless of which connection option is selected, the 656-E is built for rough-in installation behind the wall ahead of washing machines, dishwashers, and other quick-closing valve fixtures. Lifetime cycle tested to withstand 10,000 shock cycles, the 656-E can be installed at any angle and does not require an access panel, giving plumbers flexibility when routing supply lines in tight framing cavities. Because the 656-E is offered across both MIP and MSWT connection styles, it standardizes water hammer protection regardless of whether a job calls for threaded or sweat rough-in piping, letting a contractor stock one certified platform for the entire crew.

Key Features

  • Trade Size: 1" connection sized for direct attachment to supply piping ahead of the protected fixture.
  • Connection Options: Available with a 1" MIP threaded connection or a 1" MSWT sweat connection, covering both threaded and soldered rough-in methods.
  • Any-Angle Installation: Can be mounted in any orientation without the need for an access panel, simplifying rough-in layout.
  • Lifetime Cycle Tested: Rated to withstand 10,000 shock cycles, providing long-term protection against water hammer.
  • ASSE 1010 Certification: Certified by ASSE to the ANSI/ASSE 1010 standard for water hammer arresters, confirming performance against this recognized industry benchmark.
  • Compact Rough-In Design: Designed to be concealed behind the wall near the fixture or appliance it protects, reducing noise and strain on supply piping.

Sioux Chief 656-E – Frequently Asked Questions

1) What connection types does the Sioux Chief 656 Hydra-Rester come in?
Two connection styles. The 656-E has a 1 inch MIP (male iron pipe) thread for screwing straight into a threaded tee or female fitting on an iron pipe supply line. The 656-ES is the male sweat version, for soldering into copper. Both are 1 inch trade size, so pick based on whether the branch you are teeing off is threaded or copper.
2) Can a water hammer arrester be installed horizontally or upside down, or does it have to be vertical?
The 656 Hydra-Rester can be mounted at any angle. Orientation does not affect how it works, which is what makes it practical in a stud bay where the supply branch runs horizontally or where there is no room above the fitting to stand it up.
3) Does this water hammer arrester need an access panel behind the wall?
No. The 656 Hydra-Rester is built for concealed rough-in and does not require an access panel, so it can be buried in the wall cavity near the fixture it protects. That matters on multi-family and commercial jobs where cutting access doors into finished walls is not an option.
4) Will a Sioux Chief 656 arrester meet a spec calling for ASSE 1010?
Yes. The 656 Hydra-Rester is certified by ASSE to the ANSI/ASSE 1010 standard for water hammer arresters, which is the listing most plumbing specs and local codes reference for this device.
5) Where should the arrester be installed relative to the washing machine or dishwasher?
Mount it on the supply branch behind the wall, as close as practical to the quick-closing valve it is protecting: washer boxes, dishwasher rough-ins, and solenoid valve installations are the typical spots. The shock wave is generated at the valve, so the closer the arrester sits to it the less banging and pipe movement you get upstream.
6) How long will a water hammer arrester like this last before it needs replacing?
The 656 Hydra-Rester is lifetime cycle tested to 10,000 shock cycles. That is the basis for installing it concealed with no access panel, since it is not treated as a serviceable item in the wall.
7) How is the Sioux Chief 656 packaged, and where is it made?
It ships 4 each per case, which suits stocking a rough-in truck or standardizing on one arrester across a building's washer and dishwasher connections. Country of origin is Canada.
