Under Sink RO System – Read Through this Final Article About Under Sink RO Systems.

Water Filters are getting to be a must have appliance. Customers are becoming less confidence of Water Authorities to monitor water quality, in addition to the environment impact of plastic bottles is fuelling the acceptance of countertop ro system throughout Australia.

This explosion also brings having a sellers who have very little expertise in the marketplace who happen to be there to sell you whatever they have.

This is provided to assist you to understanding the priorities of water filtration and also the questions you should ask to make sure you receive the system that suits you. The better you understand and request, hopefully the less chance you will end up taken advantage of.

There are actually 3 main aspects of water filtration - Housings - Installation Fittings - Cartridges.

These are the basic plastic casings that enclose the cartridges. On undersink models where these 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 into the market it is recommended to only 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 manufactured in USA stamp.

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

Many consumers is probably not aware about exactly what the plumber uses to install their system, however it is strongly recommended to be informed, because most will use plastic stop valves, Saddle Valves, which simply cut with the copper pipe and they are illegal in this particular country.

An end valve to slice water off for maintenance and also a Pressure Limiting Valve to limit any spikes or hammers within the pipes is required.

Some companies get the Pressure Limiting Valve as 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 for connecting tubing to housings. We recommend the John Guest push fitting as it is quick and reliable. Also your faucet is very important and where possible a Ceramic Disk, which supplies you ¼ to full turn is the greatest option. These needs to be provided included in the package rather than an upgrade.

This is where consumers need to be aware. Repeat business with replacement cartridges is big business and some manufacturers turn to have non-standard cartridges to maintain their data base and charge want they need. A number 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 can be canister style or carbon with mesh, usually with a hole on the centre. As long as they have flat ends, without having extensions and correct length. It is recommend when it comes to an investment, you enquire as to the size and measurements from the cartridge.

Non-standard cartridges can be hard to gain access to should your supplier is no longer available. Also they could be expensive as you may 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 have grown to be popular for their comfort of replacement, compact design and hygiene. This involves the replacing the medium and casing. If choosing this style, be sure the unit contains a standard style cartridge which can be sourced from a variety of outlets. The most famous of these represent the Omnipure Q and E Series which are readily available. Purestream, beneath the brand name Ezi-Change, has both countertop and water faucet filter incorporating this technology.
