Water Filters are getting to be an absolute must have appliance. People are becoming less confidence water Authorities to keep track of water quality, along with the environment impact of plastic containers is fuelling the acceptance of Reverse Osmosis Systems throughout Australia.
This explosion also brings by using a sellers that have very little familiarity with the marketplace who are there to market you what they have.
The following is provided that will help you knowing the priorities of water filtration and the questions to ask to make sure you have the system that meets your requirements. The greater you already know and ask, hopefully the less chance you will be taken benefit from.
There are 3 main elements of water filtration – Housings – Installation Fittings – Cartridges.
These are the plastic casings that enclose the cartridges. On undersink models where they can be subject to mains pressure, they have to meet Australian Standards AS3947 which demands a burst pressure of 35000 kpa or 550 psi. With a growing number of Asian product coming on the market it is recommended just to purchase USA manufactured housings to make certain no burst housings or flooded kitchens.
All Purestream housings are manufactured by QMP reputable US manufacture comply with Australian Standards AS3947 and carry the created in USA stamp.
These parts should be brass or chrome and normally incorporate an inline compression tee connections, flexible hose or dishwasher connection for quick installation.
Many consumers might not be conscious of just what the plumber uses to put in 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 so are illegal with this country.
An end valve to reduce water off for maintenance as well as a Pressure Limiting Valve to limit any spikes or hammers in the pipes is required.
Some companies have the Pressure Limiting Valve as an option claiming their housings are Australian Standards approved and do not require one. Will not install under sink water filter with out a Pressure Limiting Valve. Some inline plastic Apex valves are fine.
Most units will contain fittings in order to connect tubing to housings. We recommend the John Guest push fitting because it is fast and reliable. Also your faucet is vital and where possible a Ceramic Disk, which gives you ¼ to full turn is the best option. These must be provided in the package and not an upgrade.
This is when consumers have to be aware. Repeat business with replacement cartridges is very large business and several manufacturers look for have non-standard cartridges to maintain their data base and charge want they want. Several of the non-standard models are Raindance, Aquaspace, Pureatap, Everpure.
Standard cartridges are 25 cms Or commonly referred to as 9 ¾” or 10”.They are often canister style or carbon with mesh, usually using a hole across the centre. If they have flat ends, with no extensions and correct length. It can be recommend when thinking about an investment, you enquire as to the size and measurements of your cartridge.
Non-standard cartridges can be difficult gain access to should your supplier is not really available. Also they may be expensive when you simply do not possess a alternative. Everyday we replace customers housings because it is less expensive than accessing the ‘non’standard’ cartridges.
Twist-off or bayonet style cartridges are getting to be popular because of their comfort of replacement, compact design and hygiene. This requires the replacing of the medium and casing. If choosing this style, ensure that the unit boasts a standard style cartridge which can be sourced from many different outlets. The most popular of these are the basic Omnipure Q and E Series which are plentiful. Purestream, within the manufacturer Ezi-Change, has both countertop and water faucet filter incorporating this technology.
