FAQ

YES – with the following requirements.

• Installation in accordance with AS/NZS3500.
• Installed within elson EPS corrugated sleeve conduit.
• Must be sleeved when penetrating through a slab.
• Installed in a single continuous length without fittings.

YES – when installed in accordance with AS/NZS3500.

NO – Australian Standards do NOT allow PE-X Pipe to be used on the flow and return lines between solar panels and solar storage vessels.

YES – but you MUST follow the Jointing and Installation Procedure Instructions in this Handbook. Attention to detail and strict adherence to these instructions will ensure trouble free installations.

It is absolutely essential and a requirement of the Jointing and Installation Procedure to ensure the pipe jointing section is completely free of scratches, scars, scrapes, indents and any dirt, mud, sand or any other foreign matter.

NO – It is not recommended to use previously installed EPS Push-Fit pex fittings as the integrity of the “O-Ring” seal and grab ring cannot be guaranteed. In the case of a new installation where a fitting has just been installed, you may be able to Re-Use the fitting under the following requirements:

• The fitting must be completely intact including all components.
• The “O-Ring” must have no damage.
• The Grab Ring must have no damage.
• The fitting and all parts must be completely clean and free of any dirt, sand, grit, foreign matter.
• The pipe MUST be Re-Cut above the Grab Ring indentations and at a point where there is no sign of any scratches, scars, scrapes or indents that will align with the depth of the EPS Push-Fit pex fitting.
• ccordance with the instructions in the EPS Push-Fit pex handbook.

NOTE: If you are unsure about any of the above listed points then you must dispose of the fitting in a responsible manner to ensure it is never Re-Used.

Following the jointing procedure in this handbook allows for checks to confirm complete insertion. These include the following key points:

• Cut the pipe at one of the pipe graduation marks and the fitting must then Push-Fit to the next mark.
• The EPS Push-Fit Depth Gauge and Deburring Tool makes a feint mark on the tube as an indicator to where the fitting must be inserted.

NO – NEVER DO THIS! Attempting to pull out the fitting after it has only been partially inserted causes the Grab Ring to “Dig-In” to the pipe leaving a permanent scar which will destroy the integrity of the joint and leak. IF THIS OCCURS you MUST use the Disassembly Tong to release the fitting, then Re-Cut the pipe above the Grab Ring indentations and at a point where there is no sign of any scratches, scars, scrapes or indents that will align with the depth of the EPS Push-Fit pex fitting. Always use the EPS Push-Fit Depth Gauge / Deburring Tool.

With every installation you MUST always inspect the pipe first to ensure it is EPS pipe with Licence number WMKA21274. Other PEX pipe is not manufactured to the same stringent quality controls and fine tolerances as elson EPS pipe, making other brands incompatible with EPS PushFit pex fittings.

YES – failure to use the Depth Gauge / Deburring Tool will void your warranty. Use of this tool is a requirement in accordance with the Installation Instructions and Jointing Procedures. The Depth Gauge / Deburring Tool has two main roles, 1. It marks the pipe with a feint line to confirm a “Safe Bury” insertion depth and 2. It deburs the pipe end to prevent damage to the “O-Ring” allowing easy insertion.

YES – It is recommended to incorporate a check system to confirm that every joint has been pushed in and inserted completely up to the pipe graduation mark and/or the Pipe Depth Gauge / Deburring Tool mark.

YES – follow all of these important steps below:

• Ensure that the tool is compatible with EPS GAS PEX-AL Pipe and EPS Crimp Gas Fittings
• Ensure the tool is in good working order
• Ensure that the jaws align and have no gap when closed
• Ensure that the jaws are clean, free of defects and debris
• Refer to the Jointing Procedure in this manual for correct method

YES – follow all of these important steps below:

• Ensure that the tool and jaws are compatible with EPS GAS PEX-AL Pipe and EPS Crimp Gas Fittings
• Read and recognise the instructions contained in the manual
• Ensure the correct jaws match the tool, the pipe and the fittings
• Inspect the tool to ensure it functions properly
• Inspect the jaws to ensure they’re clean, dry, free of dirt grit and corrosion

YES - you should visually inspect each fitting to ensure it is free of any dirt and grit and all parts are undamaged – clean/ replace/discard as required.

YES, ALWAYS:

• After heating and brazing allow the fitting to cool fully before inserting pipe.

• Must only be installed by a licenced Gas Fitter
• Must be installed in accordance with AS/NZS 5601
• Must be installed using the EPS Crimp Gas PEX-AL Piping system procedures
• Must be installed using EPS Gas PEX-AL pipe, EPS Crimp Gas fittings and tools, licence SMKP 21859

YES, always inspect the pipe and ensure it is cut square, has been “rounded & deburred”, has no rough edges and the internal and external pipe is undamaged prior to crimping.

YES – you should check every crimp joint has been Compressed properly by testing with the crimp gauge.

Inspect the fitting to ensure the pipe is visible through all two witness openings.

YES – with the following requirements.

• Installation in accordance with AS/NZS3500.
• Installed within elson EPS corrugated sleeve conduit.
• Must be sleeved when penetrating through a slab.
• Installed in a single continuous length without fittings.

• Read and recognise the instructions contained in the manual
• Ensure the correct jaws match the tool, the pipe and the fittings
• Inspect the tool to ensure it functions properly
• Inspect the jaws to ensure they’re clean, dry, free of dirt grit and corrosion

• Release the trigger and jaws by actuating the retract slide
• Recharge the battery or replace with charged battery
• Re - Crimp the joint and check with the crimp gauge
• Cut off the pipe and fitting if it fails to crimp properly

YES - this is a requirement for every joint – ensure that the reaming/calibrating tool suits EPS Gas PEX-AL pipe

YES - you should visually inspect each fitting to ensure it is free of any dirt and grit and all parts are undamaged – clean/ replace/discard as required.

YES, always inspect the pipe and ensure it is cut square, has been “rounded & deburred”, has no rough edges and the internal and external pipe is undamaged prior to crimping.

YES – you should check every crimp joint has been Compressed properly by testing with the crimp gauge.

Inspect the fitting to ensure the pipe is visible through all two witness openings.

YES - EPS Crimp Water and Gas Dual fittings are dual approved for water and gas.

Elson will warrant the first joint only when transitioning to EPS Crimp system on connecting to an approved compatible system.

• Release the trigger and jaws by actuating the retract slide.
• Recharge the battery or replace with charged battery.
• Re- Crimp the joint and check with the crimp gauge.
