Water Hammer - 1
INTRODUCTION
Ryemetal has for many years been a leading exponent in highlighting the detrimental effects water
hammer generates within domestic and industrial plumbing systems throughout the country. To combat
the consequences of water hammer, Ryemetal is proud to offer the Sioux Chief range of water hammer
arresters.
Water hammer is the term used to define the destructive force produced in a piping system when the
water flow is suddenly stopped by the rapid closure of a valve or device. This rapid closure induces an
intense pressure wave to travel back and forth through the pipe work, resulting in pipe vibration and a
hammering effect. The vibration and hammering can be of such an intensity pipe work may fracture,
resulting in flooding and expensive repairs.
The water hammer arrester works on the principal of compressing air to absorb the induced pressure
wave. The arrester is placed at 90° to the water flow, just upstream from the offending device. When the
device closes the pressure wave begins to move back along the pipe. As it reaches the arrester the force
acts against a piston which in turn pushes against a charge of air, the air is compressed, dissipating the
wave energy and nullifying the hammering effects.
Sioux Chief water hammer arresters undergo stringent factory testing (500,000 cycles of actual hammer
conditions). All Sioux Chief water hammer arresters are manufactured from highest quality type L copper
tube, are cold rolled and spun closed seamless. BSP threaded DR brass fittings are secured by lead free
soldered joints.
WARRANTY
Ryemetal warrants that the products supplied will be free from defects in materials, workmanship and
performance for a period of 5 years from the date of purchase. If within such period any of the products
are proved to Ryemetal’s reasonable satisfaction to be defective, such products shall, at Ryemetal’s
discretion, be replaced. This warranty applies in respect of a defective product only if it was installed
in accordance with supplied instructions and existing plumbing codes, was not subjected to abuse
and was at all times used in a manner consistent with its intended use. This warranty does not apply to
products damaged by abuse, accident, misuse, neglect, alteration, repair, disaster, improper installation
or improper testing

SIZING OF ARRESTERS
Rye-Sioux Chief water hammer arresters are sized in accordance with the capacity of the arrester air
chamber. This capacity determines the suitability of the arrester for any given application and is identified
by the corresponding assigned letters eg. ‘AA’. A fixture unit is a quantity in terms of which the load
producing effects on the plumbing system of different types of fixtures are expressed on an arbitrary scale.
Washing machines and dishwashers are to be treated as remote installations. Rye Australia recommends utilizing
‘AA’ or ‘A’ size arresters at each supply point for these appliances.
Example:
Residence with:
1 x WC (cistern)
3 cold fixture units
0 hot fixture units
1 x bathroom group (no WC)
3 cold fixture units
3 hot fixture units
1 x laundry tub
3 cold fixture units
3 hot fixture units
1 x kitchen (combination)
3 cold fixture units
3 hot fixture units
Total cold fixture units = 12
‘B’ size arrester required on cold supply
Total hot fixture units = 9
‘A’ size arrester required on hot supply
Water Hammer - 3
ARRESTER SIZE CALCULATION
Example:
Length of branch pipe is 15 m (1500 cm)
Change in water velocity is 3 l/s (3 – 0 = 3)
Gauge Pressure, valve open is 420 kPa
Pipe I.D. is 60 mm (6 cm)
Chart Intercept at
1035
=2
420 + 100
From the chart Y = 27
C=
8880 x 1500 x 9
= 237cc
36 x (420 + 100) x 27
From the chart it can be seen that the capacity of 237cc lies between ‘C’ and ‘D’ sizes. The arrester
choice must be larger than the calculated volume so the ‘D’ size is the correct device for this example.

DESCRIPTION
Rye-Sioux Chief Hydra-Rester water hammer arresters are available in all
sizes to ensure the correct capacity may be selected for any application.
The Hydra- Rester is formed from type L copper tube and is cold rolled and
spun closed seamless. The piston carries two EPDM seals and is lubricated
with approved 111 Silicone Compound. System surge pressure can be kept
below 1000 kPa while the arrester can operate at a safe working pressure
to 2300 kPa. The device is easily installed via the versatile BSP male thread
and can be fitted in any position 90° to the pipe work.
FEATURES
• Simple to install
• Maintenance free
• Cost effective
• Seamless shock absorbing
chamber
• Multiple choice of sizes
OPERATION
APPLICATION
Upon an offending fixture closing, the pressure wave begins to move back
along the pipe. As it reaches the arrester the force acts against the arrester
piston, which, in turn, pushes against a charge of air, the air is compressed,
dissipating the wave energy and nullifying the hammering effects.
Hydra-Rester water hammer
arresters are ideal for installation in all domestic, commercial or industrial plumbing
systems.
Rye-Sioux Chief Hydra-Rester water hammer arresters are easily installed at
90° to the pipe work by utilizing the appropriate Rye BSP ‘T’ fitting. Where
there is one known offending fixture the arrester should be located upstream within one metre of this fixture. In a multi fixture branch line up to six
metre the Hydra-Rester should be placed at the end of the branch between
the last two fixtures served.Water hammer arresters do not compensate for
loosely fitted pipe work.
All plumbing systems must be structured in accordance with AS 3500.1 and
utilise the correct clipping and supports.
SPECIFICATION STATEMENT
Water hammer arresters shall be the Hydra-Rester as distributed by Rye Australia and manufactured by Sioux Chief. Arresters shall be of the piston type
with a seamless, type L copper chamber and have a permanent air charge
above a two o-ring piston. Units shall be Watermark approved.
