    In tank Resin Filter

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Does anyone know where I might obtain some information about this filter? I have PM'ed Bombora over a week ago but no response.

    Bombora Coffee & Water Supplies :: WATER FILTRATION :: COFFEE & ICE FILTERS :: Coffee Machine Replacement Water Filter, In-Tank, Resin

    Basically, I am in a soft water area (doesn't even measure on a water hardness strip). This filter seems like it would be just what I need.

    What information are you looking for? It's a filter commonly found attached to the intake hoses in the water reservoir of E61 tanks (my Diadema Perfetta included).

    What information are you after?
    They are a fairly common item used by a lot of tank fed machines.
    Bombora have a retail site called Fridge Filters that I have ordered off before:
    Fridge Filters Australia :: WATER FILTRATION :: COFFEE & ICE FILTERS :: In-tank Resin Water Filter
    There is also a contact number on the top right of that page you could use to talk to them.

    I bought this once for the duetto but removed it because the pump made a strange noise at the start of each pull. Its probably more suited for a vibe pump rather than a rotary one.

    I just want to know what exactly it filters? A data sheet? What it is suitable for? If it suits my purposes?

    Do you use any other water softening or filtering in addition to this?

    The in-tank resin filter can only do so much. It is certainly not a compete softening or filtering solution.
    I personally use the Brita C150 system and refill the tank using only water that has been through it, but Bombora are the best to speak to about your specific situation.
    Either e-mail or phone is your best bet as PM's will only be seen when the sponsor is online here.

    Im using a bench filter from a local water shop. I think it's called a royal doulton with an ultracarb filter, and I replace the cartridge each year.

    I use a bench top filter and a Brita Maxtra jug as well as the in tank filters that came with my Breville DB. Bombora handle Brita filters.

    Bombora and other sponsors will set you up to successfully minimise scale in your machine.

    I check the positive effectiveness of my treatment with a carbonate hardness test kit I bought for $14 from a fish tank shop.

    To check for water filter scams look for H2O dot scam.

    I understand that ion exchange resin water softening filters can be recharge by soaking them in brine (salty water} for a few hours, then in fresh water to remove excess salt. Some whole of house ion exchange water softeners have an automatic salt flushing system.

    While the latest replacement Breville filters are said to be carbon filters, I believe they contain both activated carbon and ion exchange resin.

    Thanks Barry. The Minore's manual says to siphon a saline solution through the filter (removed from the tank, of course!), repeating the process with fresh water. I have no idea how salting the filter, then rinsing out the salt with fresh water actually recharges the resin beads. It seems like a recipe for accelerating corrosion.

    Hey Bern as far as I know i dont have a small in-tank resin filter unless it came with the machine and was installed at factory

    I only use that filter for my Giotto and have been since day 1

    Contrary to popular believe not all areas in perth has hard water. if you live in the bush or central regions then more than likely yes

    However, the metro areas are all fed treated water and some areas use dam water as apposed to ground water
    Thankfully, my area falls within the area that gets its supply direct from a dam/water catchment as I have been told

    You can also acquire water test results from your local water authority that is usually on the respective websites
    A google search for something like "2012 Water Quality Report Sydney" would turn something up

    The filter I use does have a in built water softener as well anyway

    I hope it is not too technical. Here is the basic chemistry of how ion exchange water softening treatment works. I found this somewhere on the net.

    Ion exchange involves removing the hardness ions calcium and magnesium and replacing them with non-hardness ions, typically sodium supplied by dissolved sodium chloride salt, or brine. The softener contains a microporous exchange resin, usually sulfonated polystyrene beads that are supersaturated with sodium to cover the bead surfaces. As water passes through this resin bed, calcium and magnesium ions attach to the resin beads and the loosely held sodium is released from the resin into the water.

    Just on the offchance anyone is interested, I took Bernard a sample of my tap water today - it was around 120ppm on the TDS meter and total hardness was 44. Bernard said that most commercial installations aim for hardness of about 40 so I was almost there. He said that I should just use the in tank resin filter and to change that filter every 6 months.
