Maximum Working Pressure
EPS Pipe is manufactured to AS/NZS 2492 and designed to a maximum working pressure of 1600 kPa @20°C

Exposure to heat
Exposure to excessive heat can damage the integrity of the pipe and joint and will significantly reduce the service life of the EPS plumbing system. Be mindful of exposure to radiant heat sources i.e. high wattage lighting and other radiant heat sources. While welding or soldering during construction and maintenance in close proximity to the EPS Plumbing system. EPS Plumbing system exposed to heat emissions must be permanently protected. Never expose EPS plumbing system to a naked flame. Replace all pipe and fittings that have been compromised due to direct or radiant heat. Always follow required installation procedure as per AS/NZS 3500.

INSTALLATION REQUIREMENT

CARE & HANDLING
EPS LEAD FREE* CRIMP Pipe & fittings. Must be protected from damage through all stages of the process from transport to storage and installation in accordance with AS/ NZS3500. Provision for pipe and fittings protection includes but is not limited to the following:

Important!

• Pipe expansion and contraction needs to be accommodated during installation to allow for movement due to thermal Linear Expansion. Failure to do so may exceed the torsional pull-out allowances on fittings resulting in leakage. Refer to the Pipe Specification Chart for the Thermal Expansion Co-efficient
• EPS pipe is flexible but requires care when bending to avoid kinks or other permanent deformation that may restrict flow or put undue pressure on joints. If the pipe is kinked or damaged in any way it must be cut-out and replaced.
• Elson EPS Crimp profile pipe bends are available when required. Refer to the Pipe Specification Chart for minimum bending radius.
• Connecting Barb soldered connection require special attention. Solder the brass connection barb first then allow to cool before jointing.
• In accordance with AS/NZS 3500, regions with extreme hot or cold temperatures, require appropriate insulation for protection and compliance. Consideration should also be given to insulating the pipe for energy efficiency as well as the prevention of condensation which can occur in hot and cold lines.

Pipe support and clipping
Pipe support and clipping, both vertically and horizontally is required to ensure conformance for vibration, excessive tension, torsion or compressive stresses on fittings and pipe. Refer to Pipe Specification Chart for spacing

• Pipe penetrations through timber and steel frames and concrete sections must conform and may require protection using grommets, fire collars, sleeving or wrapping. Holes, notches and cut-outs must be accurately drilled “in-line” to allow movement for expansion and contraction of the pipe and fittings so joints are not exposed to excessive stress. Refer to Pipe Specification Chart for timber frame cut-out limitations.
• Pipe expansion and contraction needs to be accommodated during installation to allow for movement due to thermal Linear Expansion. Failure to do so may exceed the torsional pull-out allowances on fittings resulting in leakage. Refer to the Pipe Specification Chart for the Thermal Expansion Co-efficient.
• EPS pipe is flexible but requires care when bending to avoid kinks or other permanent deformation that may restrict flow or put undue pressure on joints. If the pipe is kinked or damaged in any way it must be cut-out and replaced. EPS Push-Fit elbows are recommended for tight bends.
• In accordance with AS/NZS3500 regions with extreme hot or cold temperatures require appropriate product selection and/or insulation for protection and compliance. Consideration should also be given to insulating the pipe for energy efficiency as well as the prevention of condensation which can occur in hot and cold lines. Hot water lines require insulation / lagging – Refer to AS/ NZS3500.

Clipping Distance
Pipe support and clipping, both vertically and horizontally is required to ensure conformance for vibration, excessive tension, torsion or compressive stresses on fittings and pipe. Refer to Pipe Specification Chart for spacing.

Underground Installation/Concrete slabs

NOTE: It is a requirement to pressure test the pipe and fittings in accordance with AS/NZS 3500 prior to burying or concealing the EPS Plumbing System. Underground installation of EPS pipe and fittings must be in accordance with AS/NZ3500 including but not limited to the following:

• Minimum buried depth required by standards.
• Minimum pipe separation distance.
• Wrapping and protection.
• Conduit sleeving through slab penetration.
• Underground Piping installation recommended with no joints.
• Concrete slab piping must be continuous with no Joints.

Exposure to UV Rays.
Pipe must be protected from long term or permanent U.V. exposure, by way of lagging, or encasing in a conduit. AS/ NZ 3500 outlines installation practices and considerations the installer must abide by.

EPS PEX pipe is specifically designed for the EPS CRIMP plumbing system in conformance with AS/ NZS2492 with watermark certificate WMKA21274. EPS PEX pipe is compatible with all two EPS jointing systems for water including:

• EPS LF Crimp
• EPS LF Push-Fit

System Testing
Pipe and joint system testing must be carried out in accordance with AS/NZS3500 and any other applicable local authority requirements prior to burying or concealing the EPS Pex Plumbing System. It is the responsibility of the Licensed Installer to ensure that all joints and fittings are inspected, tested and checked for leaks to ensure safety and compliance. It is recommended to incorporate a checking procedure to ensure that each joint has been correctly and completely jointed.

ELECTROCUTION WARNING!
The potential threat of electrocution and death must be recognised if an earth line is disconnected by cutting metal pipes. ALWAYS check with a licenced electrician prior to proceeding.

Ring Mains/Recirculating Hot Water Systems
If not configured correctly, the entire plumbing system may have a dramatically reduced service life.

Recirculating Hot Water Systems or Ring Mains minimise the time it takes to get hot water to reach an appliance or outlet. It is also known that the continuous flow of water with exposure to high temperatures and high velocity makes this a very extreme and demanding application, whether using copper, Pex, or other piping materials.

To ensure system service life is maximised and to cater for the performance tolerances of heat sources, the following installation and water quality guidelines must be followed on any circulating hot water systems using EPS plumbing system in order to maintain the product warranty.

Maximum pressure within the ring mains / recirculating hot water systems must be limited 500kPa (as per AS/NZ 3500). Maximum water temperature must not exceed 60°C.

The pipe work design and recirculating pumps must be sized to limit the water velocity to the requirement of AS/ NZS 3500 for non-metallic piping. Where copper pipe is part of the installation, the velocity restrictions for this material is extremely critical and must not be exceeded.

A timer controlled recirculation pump must be used with a maximum circulation time of 12 hours per 24-hour period. All pipe work should be insulated and the recirculating pump must be thermostatically controlled, to further reduce stress on the system and minimise energy consumption.

The system layout of pipework and fittings should be designed with long wide sweeping pipe bends with limited use of fittings. Water quality – Australian city potable water reticulation systems as defined in the Australian Drinking Water Guidelines.

Pressure Loss
Pressure loss calculations using the Hazen-Williams equation. The pressure loss was calculated for both the internal mean inside diameter of SDR 9 of AS/NZS 2492:2007. To generate the theoretical calculations, the following assumptions were applied:

• Friction coefficient of plastic pipe at 15.5°C was taken as 140.
• The internal diameter used for calculation was taken at the theoretical mean diameter as per the manufacturing tolerances featured in Table 3.1 of AS/NZS 2492:2007 for SDR 9.

The following is a list of limitations of the Hazen-Williams equations but not limited to:

• Published literature suggests that the Hazen-Williams equation is reliable for water at 15.5°C with velocity flow less than 10 feet/s or 3.048 m/s.
• Changes in water temperature, density and media will alter the pressure loss.
• Installation where pipework which is curved or bent could alter the internal diameter
• Installation of fitting and valves within pipeline network.
• Variations in manufacturing tolerances of wall thickness and internal diameter of the PEX pipe in each SDR class.
• Variations in the actual internal surface friction coefficient.

When used to calculate the head loss with the International System of Units, the equation becomes:

Where:
• S = Hydraulic slope
• hf = head loss in meters (water) over the length of pipe
• L = length of pipe in meters
• Q = volumetric flow rate, m3/s (cubic meters per second)
• C = pipe roughness coefficient
• d = inside pipe diameter, m (meters)
Note: pressure drop can be computed from head loss as hf × the unit weight of water
(e.g., 9810 N/m3 at 4 deg C)
