    So just thought that i will share this DIY fix here hopefully somebody can benefit by this.
    after searching all over for a replacement impeller shaft which turned out fruitless i decided to come up with this fix. 1. good old fashioned welding rod.
    2. remove all the flux and sandpaper nice and smooth with water sandpaper fine one.
    3. cut to the correct size insert and reassemble and bobs your uncle works like a bomb.
    cheers Paul.

    If the rod gets warm you should find a different fix as it can mess with the magnetic fields, reduce the efficiency. That is one reason some sort of ceramic shaft is used and ceramic is also quit hard.

    Try pet masters or phone daro directly and ask for a retailer who has stock.

    Thanks for pointing this thread out, I did follow the instructions below and it worked, I also managed to get a different impeller head on there that fits, should be fine till the actual proper parts arrive.

    Earlier years yes, but these days most come with ceramic shafts as ceramic is the better option were longevity of impeller assembly is concerned. Something to do with tensile elasticity if I recall correctly. Only con is that ceramic shafts do need to be handled with case during filter maintenance.

    Stupid question. If a ceramic shaft is broken in 2, will it not be easier to fix with epoxy?

    Thanks you are a life saver. I bought the filter filled the tank and was ready to cycle when I noticed the damage.

    Technically stainless steel has a better tensile strength than ceramic. Only reason I can think of why ceramics are being used is because it handles friction better and absorbes heat and releases it much faster.

    Tried the surface between the two pieces is so small and any of the glue that manages to seep out creates imperfections on the shaft.

    My 2213 shaft broke three or four years back, Ebh at Sams DIY'ed a metal one in a few ticks and the filter performance has been 100s since then and I don't have to stress each time I pull it out or clean it as I did with the brittle ceramic one ....

    Conclusion, there are advantages for both fabrics..

    Agreed, cannot understand why they would use something so fragile for something that is so critical to the operation of the filter.

    Business opportunity then to make and sell stainless rods as replacements

    As mentioned, the move to ceramic seems to be motivated by overall longevity of pump as well as noise reduction.

    I'm sure the research and testing has proved ceramic shafts have advantages that's a given. All I'm suggesting is that in my case a s's steel shaft has proved over several years that it's a pretty good easy to obtain alternative and I have peace of mind it won't break over a week end when I next service my canister. I have one s's shaft and at least ten ceramic...
