Who type of crimping Jaws are suitable for G-Pex piping system?
Please make sure to use U profile of jaws.
What is Pex-AL-Pex?
Pex-Al-Pex: G-Pex aluminum plastic composite pipe Medium layer of aluminum plastic composite pipe is welded aluminum band, and inner and external layers are all made of polyethylene.
Special-purpose hot melting adhesive is used, and extrusion molding method is adopted for composite of pipe. Pressure resistance of metal pipe and corrosion resistance of plastic pipe are combined together on the pipe.
Why choose G-Pex piping system?
G-Pex Piping system is more cost effective in terms of material, labor, time and installation.
No welding, brazing or soldering required. No expensive oxy acetylene equipment.
Eliminate water hammer.
Low startup cost for the tools.
Color coded pipe for quick identification – blue pipe for cold water, red pipe for hot water, yellow pipe for gas, green pipe for rain water and lilac pipe for recycled water..
Pex won’t corrode. If you live in an area with acidic water, Pex is unaffected by acidic water and is therefore a better choice.
Why some people choose Pex Only pipes (no metal layer)? How many types are Pex Only pipes? What are the differences?
Pex Only pipes are lower cost general purpose piping system for water only. It is generally divided into 3 main types: A, B and C. It is a misconception to think that one type is better than the other simply because it’s an A, B, or C type. These letters are used to identify the manufacturing process and have nothing to do with quality of performance ratings.
In fact, some may find it surprising that:
1. PEX-B, for example, can withhold higher pressure than PEX-A.
2. PEX-B, on the average, performs 30-40% better in chlorine testing than PEX-A and PEX-C.
How many joining methods for Pex Tubing? Which system is the most cost effective and easy to use?
There are three types of joining methods: 1. crimp on 2. pull on 3. push on methods.
1. Crimp on System: This is the most used joining methods for pex system and most recommended method by plumbers. It is the easiest method- just insert the pipe to the fitting and crimp. Then It's done. Besides, the cost of the fittings are much cheaper than other systems. (see here)
2. Pull on system: It is more expensive than crimp on system. Joints are made by expanding the end of tubing and inserting a barbed fittings, then a metal sleeve is pulled down over the tubing using a tool to create a tight seal. (see here)
3. Push on system: As this system is over priced and leave room for errors, push on system is seldom used for buildings.
What tools are required when installing the G-Pex piping System?
The G-Pex piping system can use both hand or battery operated crimping tool with U profile of jaws which is available in 16mm, 20mm, 25mm, 32mm.
A hand reamer l is available and must be used afte cutting the pipe.
What is the warranty offered by G-Pex?
There is a 25 year warranty offered by G-Pex when installed by a licensed plumber following the AS 3500 of the National Plumbing code parts 1, 4, 5 and established installation practices.
Can the G-Pex piping System be used for the carriage of hot & cold potable water?
Yes, G-Pex piping System complies with AS 4176:2010. G-Pex piping System solves many problems associated with metal and other types of plastic pipes.
It will not scale. erode, corrode, or contaminate water.
Are G-Pex fittings interchangeable with gas & water installations?
Yes, all G-Pex fittings are the same for hot & cold water, natural gas, LPG and compressed air applications. Just one type of DR brass crimp on fittings work for all applications.
Is the G-Pex piping System compatible with other similar systems?
No. Under no circumstance can G-Pex Pipe or fittings be crimped to other similar systems. If you decide to use a particular composite system for water installations you are strongly encouraged to provide a BSP threaded fitting, in an accessible location to allow for any future extensions by another plumber. In this way you provide a safe means whereby an extension to the water supply, using an alternative composite system, steel or copper can be done. Remember it may be you looking for this fitting.
What is the minimum distance between pipe fixings?
16mm pipe size-fixings to be 1.0 metre apart.
20mm pipe size-fixings to be 1.2 metre apart.
25mm pipe size-fixings to be 1.5 metre apart.
32mm pipe size-fixings to be 2.0 metres apart.
Can I bend G-Pex pipe manually without the aid of a pipe-bender?
Yes, G-Pex Pipe is extremely flexible particularly when bending a smaller diameter pipe by hand.
How long has the G-Pex piping System been in use?
The G-Pex system has been used extensively in Europe and Asia for years.
Can I fit G-Pex piping System to an existing copper installation?
Yes, G-Pex offers pex to copper adaptors ( both side can be crimped). Sizes are ranging from 16mm, 20mm, 25mm and 32mm. Please see (www.copperpress.com.au)
Is it necessary to use the reamer every time after cutting G-Pex Pipe?
Yes, it is necessary to remove the burred edge after the cutting of the pipe. This will assist in the assembly of the joint and avoid potential damage or dislodgement of the O-rings.
The use of the reamer will comply with the warranty requirements.
Are all the threads on the G-Pex fittings different to other systems?
All threads on G-Pex fittings are either male or female are BSP threads which is a universal thread.
In what length is G-Pex piping system available?
16mm, 20mm, 25mm and 32mm are available in 50 meters coils, 32mm is available in 25 meters coils.
Can G-Pex piping system be chased in masonry floors or walls?
Yes, G-Pex piping system can be chased in masonry floors, walls without further protection of the pipe necessary.
Can I bury G-Pex piipe and fittings in the ground?
Yes, G-Pex fittings are made of DR (dezincification resistant) brass. There is no need to wrap fittings with an approved material when direct burying in the ground.
Can G-Pex Pipe be buried in concrete?
Yes, without joints, the pipe is to be placed between the top and bottom layers of reinforcement.
Can G-Pex Pipe be used above ground and exposed to sunlight?
Yes, providing the pipe is sleeved with a UV resistant product.
Can G-Pex Pipe be installed beneath a building in the ground for water installation?
Yes it can, as long as there are no joints.
Can G-Pex Pipe be installed in concealed locations such as duct voids etc?
Yes it can, with joints kept to a minimum. Our crimped DR brass joints are classed as permanent joints.
Do I need to use grommets when running Ginde Pex Pipe through metal studded walls?
The use of grommets is not required as the outer layer of G- Pex Pipe acts as an insulator in itself.
There are saddling clips available that sit in the hole of the metal frame which allows the pipe to pass through them.
Do I need a licensed plumber install Ginde Pex Pipe?
Yes, installation of water plumbing can only be carried out by a licensed plumber.
Can I braze adaptors after the Ginde Pex Pipe has been fitted?
No, all brazing or soldering must be performed on the fittings prior to the G-Pex Pipe being connected.
Sufficient time should be allowed for the fitting to cool prior to attaching G-Pex Pipe.
Is there a need to support a bend in the G-Pex Pipe?
No, once the bend has been made, it will stay in place unsupported.
Can G-Pex Pipe eliminate water hammer?
Yes, using pex pipe will eliminate water hammer as the pipe moves and absorbs the shock of sudden shut off commonly associated with copper pipe installations.
