Filter life varies according to water quality, water quantity, and frequency / standard of your filter cleaning regime. A filter maintenance guide is contained in the manual, but budget on 2-3 sets of filters per annum. Usually the first indication that filters need replacing is a noticable drop in water pressure in your house.
The UV globe typically has a life of 12-18 months but should be replaced annually. The ballast on your system has a count down timer from either 550 or 365 days depending on the system. Once the days run out, the ballast alarm will sound to indicate the globe is no longer working at optimum levels and needs to be replaced. The alarm can be silenced until you install a new globe by following the instructions on the ballast itself.
Tip: Carry a spare "first filter", (the 5 micron Pleated Pre Filter), and swap this at each cleaning inspection. See maintenance guides for further information.
Have a look at the Models page - the domestic water filters come in three types:
Citimate: A low priced option without UV ONLY for town water supply users who wish to remove chemicals such as chlorine from their whole house water supply
Ranchmate & Farmmate: Two residential models with UV for untreated water such as tank, bore, lake or river water
Ranchmate PLUS: This model has two optional addons - lamp failure solenoid and/or Aquatrip leak detection
The difference between the UV models in the Residential range is simply the flow rate supported and the ability to add optional items. To ascertain the correct flow rate, the easist way is to check the flow rate of your pump.
If you wish to purchase more than one item, you can add items to your shopping basket and once you are done identifying all the items you need, you can view the items in your shopping basket and proceed towards checkout and payment.
Granular carbon filters are made up of coarser particles, and some actually allow water to set up a passage of least resistance through them (a water track), such that the granular carbon is less able to do its normal efficient job of absorption of water contaminants
We recommend using a licensed plumber who can supply the hose connectors / additional piping to suit your own water line, which may be typically 1", 1 1/4", or 3/4".
However, if you are on town water you could maximise the removal of fluoride by using two activated carbon filters in your system, substituting your Pleated Pre-Filter with a second activated carbon block filter
