Water Filters have become an absolute must have appliance. Customers are becoming less confidence water Authorities to check water quality, in addition to the environment impact of plastic containers is fuelling the acceptance of Reverse Osmosis Systems throughout Australia.
This explosion also brings having a sellers who have hardly any understanding of the industry that are there to market you anything they have.
The following is provided to assist you to knowing the priorities of water filtration along with the questions you should ask to make sure you have the system that fits your needs. The greater number of you know and inquire, hopefully the less chance you will end up taken good thing about.
There are actually 3 main elements of water filtration – Housings – Installation Fittings – Cartridges.
They 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 demands a burst pressure of 35000 kpa or 550 psi. With more and more Asian product coming on the market it is strongly recommended to simply purchase USA manufactured housings to guarantee no burst housings or flooded kitchens.
All Purestream housings are manufactured by QMP reputable US manufacture abide by Australian Standards AS3947 and carry the produced in USA stamp.
These parts must be brass or chrome and normally incorporate an inline compression tee connections, flexible hose and/or dishwasher connection for easy installation.
Many consumers may not be conscious of precisely what the plumber uses to setup their system, however it is recommended to get informed, because most will use plastic stop valves, Saddle Valves, which simply cut throughout the copper pipe and they are illegal within this country.
A stop valve to reduce water off for maintenance as well as a Pressure Limiting Valve to limit any spikes or hammers from the pipes is required.
Some companies hold the Pressure Limiting Valve for an option claiming their housings are Australian Standards approved and you should not require one. Do not install under counter reverse osmosis system with no 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 since it is quick and reliable. Also your faucet is important and where possible a Ceramic Disk, that gives you ¼ to full turn is the ideal option. These must be provided as part of the package rather than an upgrade.
This is where consumers have to be aware. Repeat business with replacement cartridges is very large business and a few manufacturers turn to have non-standard cartridges to keep their data base and charge want they need. Several of the non-standard models are Raindance, Aquaspace, Pureatap, Everpure.
Standard cartridges are 25 cms Or typically called 9 ¾” or 10”.They are often canister style or carbon with mesh, usually having a hole along the centre. As long as they have flat ends, without having extensions and correct length. It is actually recommend when considering an order, you enquire as to the size and measurements of your cartridge.
Non-standard cartridges can be difficult to gain access to in case your supplier is not really available. Also they can be expensive as you may simply do not possess a alternative. Everyday we replace customers housings since it is cheaper than accessing the ‘non’standard’ cartridges.
Twist-off or bayonet style cartridges are getting to be popular for their simplicity of replacement, compact design and hygiene. This requires the replacing of the medium and casing. If choosing this style, be sure the unit boasts a standard style cartridge that may be sourced from a variety of outlets. The most common of they are the Omnipure Q and E Series which are readily available. Purestream, beneath the manufacturer Ezi-Change, has both countertop and tap water filter incorporating this technology.
