    Hi all

    I have just purchased a new filter, Eheim 2073, however to my surprise it comes with 16/22 pipe work. All my fittings, in line heater etc are made to work on 12/16. Will it be OK to use a reducer to bring the pipe down to 12/16? I hope to run the majority of the lengths in 16/22 then swop to 12/16 on the last bit just before the glass crook and outlet. I kind of want to know if this will be OK and not ruin the flow or do damage.

    Cheers

    Hi coral.

    Welcome to UKAPS :thumbup: .
    It's very unlikely you will cause any 'damage', however, your flow will be restricted by the smallest bore.
    All you can do, at this stage, is give it a go.
    Hopefully you might get away without having to upgrade everything :D .

    You don't even need to do this. Just use a section of 12/16mm pipe over the end of your fitting and then your 16/22mm pipe will fit over that snuggly to give a waterproof seal.

    Thanks for the advice guys.

    I have decided to get a Ex700 for my existing glass and have ordered a 17mm set from ebay/ HK for the Eheim.

    So I will run 2 canisters, so the flow should be better if nothing else!

    Cheers
    :)
