UV System Maintenence Notes:

Ultraviolet systems are rated based on a dosage level of UV-C radiation into the water (mJ/cm²), with 30mJ/cm² being the standard level of disinfection and a minimum dose of 40mJ/cm² required to comply with Australian Drinking Water Guidelines. Our lamps are rated with a 9000 hour (1 year) lifespan, after which point the lamp will naturally degrade and the level of radiation produced by the lamp cannot be guaranteed.

The UV lamp sits inside a quartz thimble, which protects the electrical components of the lamp from making contact with the water. We specifically use quartz (fused silica) for this application because it is strong, exhibits thermal resistance, and has excellent UV transmission properties.

However, over time, metal ions fused within the silica structure of the quartz thimble interfere with the UV-C radiation produced by the lamp, which reduces the UV transparency of the glass and causes it to become fragile. This process is called solarization.

Tannin, bio-film, algae, and scale can also build up on the outside of the glass thimble, further preventing ultraviolet light produced by the lamp from penetrating through the thimble, and impairing the system's ability to sanitise the water passing through.

Thus, we recommend replacing the lamp every 12 months, and the thimble every 1-2 years.

Return Policy

Due to the nature of the products we sell, a strict return policy is in place. We work with food-grade certified materials that must be un-opened and un-used, so as to be able to be re-sold. This policy falls in line with the Australian Consumer Law, which is designed to protect BOTH BUYERS AND SELLERS. 

You may receive a refund or credit of equal amount, less the Restocking/Out-of-Pocket Shipping Expense Fee, if applicable, and any other deductions that are relevant. 

• 30-Day Returns Policy: Returns will not be accepted without prior approval or after 30 days of the invoice date.
  
  
• Wrongly Purchased Items/Changes of Mind Policy: Wrongly Purchased Items, or Change of Mind Purchases may be returned for a merchandise credit. This applies to, but is not limited to purchases of products that are:
  • The Wrong Size;
  • The Wrong System;
  • The Wrong Replacement Pack;
  • Due to a Change of Mind;
  • Due to Buyer Error, whereby the buyer has failed to conduct proper due diligence (including contacting FSA prior to purchase in order to clarify the relevant technical specifications, compatibility, requirements etc.) to ensure the product purchased from us is the correct product for their requirements.

• Restocking/Out-of-Pocket Shipping Expense Fees Policy: All returns will incur a 17.5% restocking fee OR an out-of-pocket shipping expense fee, whichever is greater. 
  • This fee is in place to cover the administrative expense incurred in processing the return and/or the out-of-pocket expenses incurred by us in shipping the item to you. FSA may use its discretion to determine the restocking fee. Please note this policy falls in line with the ACL, and is designed to protect us as the seller from losses incurred due to buyer error. This means that you will NOT receive a full refund of the original purchase price - you will bear the cost of shipping the product back to us, and then you will receive a credit equal to the purchase price of the product LESS the Restocking/Out-of-Pocket Shipping Expense Fee. Please refer to our Shipping Policies (below) for further clarification.
  • Low-Value Returns: Please note that with low-value items, sometimes the cost of sending the item back to us may be more expensive to you, than simply keeping the item. For example, let's say you have ordered 3x meters of the wrong-sized tubing for your needs and paid $12.00. If, for example, it cost us $7.69 to send the item to you, and it would cost you $7.69 to send the item back to us, overall you would be $3.38 worse off (due to incurring $7.69 to send the item back to us, and having $7.69 taken out of the credit) than if you had kept the item and re-ordered the correct product for your needs. 
    
    
• Shipping Policies: 
  • Free Shipping Offer: As part of our offer of Free shipping Australia-Wide, FSA reserves the right to select the most cost-effective courier to effect delivery of the product to you. We make no guarantee as to how long an item will take to arrive due to unforeseen circumstances outside of ours/the couriers' control, including but not limited to: Staff Shortages, Supply Chain Demand, Extreme Weather Events etc.
  • Express Shipping Policy: If you require an item on an urgent or Express basis, it is your (the buyer's) responsibility to contact us directly by telephone on [phone removed by eBay] prior to purchase, in order that we may quote you the options available for Express Delivery to your nominated address, and to organise additional payment for this Express Service. Express Shipping is not included in our offer of free shipping - this service will come at an additional cost payable by the buyer. 
  • Late Shipping Policy: Given that we offer the option for customers to organise Express Shipping with us prior to purchase, cancellations or refunds will NOT be issued on the basis of late or delayed shipping where the customer has opted for our Free Shipping offer. If the item (sent via Free Shipping), arrives late and the buyer wishes to return the item on this basis, the buyer will be liable for the cost of returning the product to us and a Restocking/Out-of-Pocket Shipping Expense Fee will be applicable to the return, as per the listed returns policy line items above. The customer will be issued a merchandise credit.
  • Our offer of Free Shipping does not apply to Returns: Whilst we offer Free Shipping, this does not mean that there is no cost to ship the product - obviously, a shipping expense is incurred, and as with all e-commerce operators that offer Free Shipping, the cost of shipping the product from our warehouse to your nominated shipping address is built into the price of the product. The offer of Free Shipping therefore only applies to the act of FSA supplying the product to you, and does not cover the cost of returning the product from the customer to FSA.
  • Returned to Sender Items: In the case of the buyer being unavailable to sign, refusing delivery, or the item being sent back to us for whatever reason, FSA may, at its discretion, pass the cost of the product being Returned to Sender (i.e. being returned back to us), back onto the buyer. Refer to Restocking/Out-of-Pocket Shipping Expense Fees (above).
  • Lost Parcels: If an item is deemed to be LOST IN TRANSIT by the courier, the customer is entitled to a replacement product or refund in line with the ACL. In the case of a replacement product, FSA reserves the right to send the replacement product in line with its Free Shipping offer. If you do require the replacement item urgently, please get in touch with our customer service team directly to organise Express Shipping. 
    
    
• Product Damage & Product Faults: Any damage to products that are not reported to FSA within 48 business hours of receipted delivery is not covered under our transit warranty. Return shipping is to be paid by the buyer to the address provided by FSA. It is recommended that the customer applies a transit warranty to the return freight item/s, in case of damage.
  • Faults: Should the item appear faulty or doesn’t work as described, you must supply written/photographic/video evidence of the fault to us, so that we may assess whether the unit/item must be returned for testing (if requested). If testing is requested, return postage is to be paid by the buyer. 
    • If the unit/item is deemed to be faulty, compensation will be provided for the postage cost (proof of cost required). 
    • If the unit/item is deemed to be in working order and as described, the buyer will be responsible for the cost of return postage of the product from FSA's premises, back to the buyer. 
  • Minor Damage: Any damages (minor, that can be repaired) will incur a fee, that will be deducted from the total refund which will be equal to the cost of the replacement parts (List Price) and labour charges (if applicable) to repair the system(s). This will be separate from the Restocking/Out-of-Pocket Shipping Expense Fees.
  • Major Damage: Any damage considered to be major and not feasible for repair may be refused and the return request will be void. The customer will be responsible for the return freight or disposal of the damaged unit.

Returns are not accepted on special order items unless the manufacturer allows it. Applicable fees will apply.

If you have any questions about our return policy, please contact us before purchasing. This will also help to ensure you purchase the correct product that suits your requirements.

Can I install my Water Filter on my own or do I need a Plumber?
For quality assurance and Insurance reasons, we always recommend using a licenced plumber who is familiar with water filtration. This ensures that the installation runs smoothly and is professional. If you fancy yourself reasonable at DIY type projects, we provide you with all the necessary components and instructions you need to conduct the installation yourself. Our technical support team are contactable during business hours on 1300 888 008 should you have any queries about installation.

Will Undersink Water Filters Remove Fluoride?
Standard Undersink filters will not remove fluoride from the water, we recommend using reverse osmosis as it is the safest, and most effective way of removing Fluoride from the water. There are proclaimed Fluoride Removal Cartridges on the market however they use a material called Activated Alumina which will remove Fluoride up to approx. 80% while the filter is new, but will then rapidly depreciate to the point where it is no longer effective. The other down side to the Activated Alumina cartridges is, they have a tendency to leach heavy metals into the water when the filter ages. If you do not keep a strict routine for filter replacement, it may be introducing dangerous heavy metals into your drinking water.

What are Undersink filters for?
There are a few different models of Undersink filter that each have their own specific purpose. The most common model of Undersink filter you will come across is a Sediment + Coconut Carbon configuration. As the name suggests, they have a dual action, the first filter will remove dirt/particles and sediment, while the Coconut Carbon filter absorbs chemicals from the water such as Chlorine.
Some systems elect to use a Dual Coconut Carbon Set up to double the contact time with the water. As we know that carbon efficiency is majorly to do with Contact Time adding more carbon to a system can greatly increase its ability to remove hazardous chemicals, Tannins, Tastes and odours.

Can an Undersink Water Filter remove Chloramine?
Chloramine Injection has recently been introduced into many council regions over Australia, including on the Gold Coast where FSA is based. Chloramine presents a number of issues in regards to drinking water including but not limited to; dissolving of heavy metals such as lead into the water, release of ammonia gas and adverse skin reactions. As previously mentioned, the more carbon the better. Chloramine is very hard to remove by normal means and it is removed in 2 staged. The first carbon filter acts to break open the Chloramine which in turn, releases the other various residual gasses into the water, the second carbon can then easily extract and absorb all remaining residuals, effectively removing the dangerous Chloramine from your drinking water.

How often should I change the filter cartridges?
Undersink Water Filter Cartridges should be changed anywhere between 6-12 months. You will usually notice a distinct change in taste of the water if you have the filters in too long. This signifies that the Coconut Carbon Cartridge is no longer working to its full capacity and is beginning to allow residual amounts of chemicals through into your drinking water. As a rule, you should not leave your filters in for longer than 12 months regardless if you are on town OR rain water.

What is filter protection equipment, and do I need to use it?
 Filter Protection Equipment is an important part of water filtration. Our products are sourced from experienced and reliable manufacturers and also carry the highest level of certification in the water filtration industry. Regardless of Brand, Make, Model or Country of manufacture, water filtration will ALWAYS be the weakest point in your plumbing. The three main causes of water filtration failure are; Overnight pressure surges, Intense Water Hammer Pressure Impacts, and thermal expansion. All of which can be addressed and prevented with a few simple pieces of equipment. A Pressure Limiting Valve is used to buffer the incoming pressure to the Australian Regulation Pressure of 500kPA. This is the minimum requirement for most insurance and warranty validation and is essential when used on Town mains / municipal water. A Water Hammer Arrestor is a copper tube looking device which is commonly found in the laundry (If you have one). It acts to absorb and dissipate pressure spikes in your water lines. Pressure spikes occur from appliances such as the washing machine or dishwasher and can magnify the water pressure tenfold which can cause serious damage to water filtration components. Water hammer gets the name by the distinct sound you hear when the shockwaves rattle loose copper pipes or worn out valves. This is something that is essential to be addressed immediately before installing water filtration. A Pressure Relief Valve is as it sounds. It is pre-set to open once the pressure reaches 110PSI, shooting that pressure/water down the drain line and easing the pressure in your water filter. This is a requirement if you intend to hook up your water filter to a fridge, chiller or ice maker. They are also a good idea to help relieve residual pressure from pressure surges (even if you have a PLV + water hammer arrestor).
