Water Filter Systems Perth

• Whole House Systems: 2–4 hours depending on complexity. A standard install (within two metres of the mains water pipe) typically takes 2 hours.
• Undersink RS2000 System: Approximately 1 hour.
• Undersink Reverse Osmosis System: Approximately 1.5 hours.

Start with consideration of your budget and go from there.

Installing an under sink or countertop system is better than no home water filtration system at all. Installing a whole house system will provide you with a much broader benefit, including health of the home appliances as well as family health.

One of the biggest factors is the location of your home. Over the years we have gained first-hand knowledge about the quality of water from each different suburb and can advise on the best water filter system that will efficiently filter your mains supply. Water quality is also determined by the age of the house and local construction works in progress.

The second factor that you should be considering when choosing a water filter system is the number of people in your home. Our 3 stage system at WestOz will serve up to nine (9) people without losing pressure, no matter how large your house is.

The third factor is the type of water you are filtering, other than scheme. If you are filtering rain, dam, or bore water, this may require an assessment to facilitate the correct system advice. We can refer you to a Perth water testing laboratory to have a professional assessment made.

Absolutely! By switching to a filtered water system at home, you will end up saving greatly long-term. Areas you will save may include:

• Fresh, clean water you can drink straight from the tap that costs less than 5cents/litre! You’ll no longer need to buy bottled water (which also helps our environment by reducing plastic wastage).
• With whole house filtration, white goods will endure by up to 50% longer without harsh chemicals being used in your washing machine, dishwasher, coffee machine etc.
• Clothing/linen will last longer, free from harsh unwanted chemicals in your water such as chlorine. Save on no longer purchasing fabric softener (whole house system).
• Time saved when cleaning areas such as the shower – No more calcium stains!

Cartridge replacement costs vary depending on system type, water usage and water quality:

• Whole House 3‑Stage 10″ System (Scheme Water): Approx. $390 per year
• Whole House 3‑Stage 20″ System: Approx. $714 every 18 months, or $476/year
• Undersink RS2000 Twin Filter: Approx. $110 per year
• Reverse Osmosis 7‑Stage System: Approx. $299 per year
• Benchtop Single Filter: Approx. $40–160 per year (varies based on cartridge type and usage)

Filter replacement schedules vary by system type:

• Whole House 3‑Stage 10″:
  • Sediment filter: every 3–4 months
  • Resin & Heavy Metal filters: annually
• Whole House 3‑Stage 20″:
  • Sediment filter: every 6 months
  • Resin & Heavy Metal filters: every 18 months
• Undersink RS2000 Twin Filter: Annually
• Reverse Osmosis 7‑Stage: Annually (includes all cartridges)
• Benchtop Single Filter: Every 6 months

Depending on which filtration system you select and how many filters are in the system, will affect which chemicals are filtered out of your tap water. For example, a Reverse Osmosis System has four-six filters versus a one or two stage system which has just one or two filters. Chemicals which may be removed when filtering water include:

• Phosphorus
• Magnesium
• Potassium
• Ammonia
• Sulphate
• Fluoride
• Chlorine
• Chloride
• Calcium
• Nitrate
• Sodium
• Barium
• Copper
• Floride
• Lead

Yes, all systems come with a 12-month warranty covering manufacturing faults. This includes defects in materials or workmanship but excludes misuse, incorrect installation or normal wear and tear.

Some people do like to re-mineralise their water if they have a 4 stage reverse osmosis system installed. These filters remove all chemicals, including some that are good for the body. Adding just a few pinches of Himalayan rock salt into your drinking/cooking water is a way to help add rich minerals back into your water.

Whole House Systems:

• If your existing pressure is already low, the system won’t help.
• For incoming pressure between 2.5–5 psi, no noticeable impact.
• If your pressure exceeds 5 psi, a pressure-reducing valve will be required.

Undersink Twin & Benchtop Filters:

• No change to pressure under normal operation. A reduced flow rate usually indicates blocked cartridges.

Reverse Osmosis Systems:

• These operate at a lower flow rate than mains pressure. If the storage tank empties, it may take up to 4 hours to refill completely.

Common causes include:

• Clogged sediment filter – Replace the cartridge
• Overdue cartridge replacement – Check when each stage was last changed
• Leaks – Inspect system; contact your supplier or a plumber if needed
• Blocked flow restrictor (undersink systems) – Replace the component
• Whole House System: Ensure all relevant taps are turned on
• Benchtop Filter: Replace the cartridge if flow has slowed
