Water Filters are becoming a must have appliance. Individuals are becoming less confidence of Water Authorities to monitor water quality, plus the environment impact of plastic containers is fuelling the acceptance of Reverse Osmosis Systems throughout Australia.

This explosion also brings by using a sellers who may have very little familiarity with the industry who are there to market you whatever they have.

The following is provided to assist you knowing the priorities of water filtration and the questions you should ask to ensure you get the system that suits you. The more you know and request, hopefully the less chance you may be taken good thing about.

There are actually 3 main aspects of water purification – Housings – Installation Fittings – Cartridges.

These are the plastic casings that enclose the cartridges. On undersink models where they are subject to mains pressure, they need to meet Australian Standards AS3947 which requires a burst pressure of 35000 kpa or 550 psi. With more and more Asian product coming to the market it is strongly recommended to only purchase USA manufactured housings to make sure no burst housings or flooded kitchens.

All Purestream housings are created by QMP reputable US manufacture adhere to Australian Standards AS3947 and carry the manufactured in USA stamp.

These parts needs to be brass or chrome and normally incorporate an inline compression tee connections, flexible hose and dishwasher connection for simple installation.

Many consumers is probably not aware of what the plumber uses to set up their system, however it is suggested to be informed, because most will use plastic stop valves, Saddle Valves, which simply cut from the copper pipe and therefore are illegal with this country.

A stop valve to cut water off for maintenance and also a Pressure Limiting Valve to limit any spikes or hammers from the pipes is mandatory.

Some companies get the Pressure Limiting Valve for an option claiming their housings are Australian Standards approved and do not require one. Usually do not install under sink water filter without a Pressure Limiting Valve. Some inline plastic Apex valves are fine.

Most units will contain fittings to connect tubing to housings. We recommend the John Guest push fitting since it is fast and reliable. Also your faucet is essential and where possible a Ceramic Disk, which gives you ¼ to full turn is the perfect option. These must be provided in the package rather than an upgrade.

This is why consumers must be aware. Repeat business with replacement cartridges is big business and several manufacturers look for have non-standard cartridges to keep up their data base and charge want they desire. Some of the non-standard models are Raindance, Aquaspace, Pureatap, Everpure.

Standard cartridges are 25 cms Or known as 9 ¾” or 10”.They are often canister style or carbon with mesh, usually having a hole down the centre. As long as they have flat ends, without extensions and correct length. It can be recommend when considering any purchase, you enquire about the size and measurements of your cartridge.

Non-standard cartridges can be hard to access if your supplier is no longer available. Also they are often expensive as you may simply do not have a alternative. Everyday we replace customers housings as it is less than accessing the ‘non’standard’ cartridges.

Twist-off or bayonet style cartridges have grown to be popular for their ease of replacement, compact design and hygiene. This requires the replacing of the medium and casing. If choosing this style, ensure the unit incorporates a standard style cartridge which can be sourced from various outlets. The most famous of they are the Omnipure Q and E Series which can easily be bought. Purestream, underneath the brand name Ezi-Change, has both countertop and tap water filter incorporating this technology.
