Reducing pipe size

[coral]

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 .
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 .

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!

That can only be a good thing in a planted tank
